W3020 GSM Multiband RF Transceiver

Description

passed through another external filter to attenuate the

image frequency to an acceptable level. The signal

passes through the RF down-conversion mixer to the

IF frequency. It is then filtered by an external surface

acoustic wave (SAW) filter to bring the in-band

blocking signals to an acceptable level. The signal is

amplified in the IF strip of the receiver. The IF strip

contains digital gain control (DGC) amplifiers at both

the IF and baseband frequencies and precision low-

pass filters. This allows the signal to be amplified

while in-band blocking signals are removed. The

precision I/Q demodulator splits the signal into its in-

phase and quadrature signals. The I/Q signals are low-

pass filtered and further amplified. The I/Q amplifier

contains integrated dc offset calibration circuitry. The

outputs (I/Q) are fed to the ADC for further signal

processing.

The W3020 is a highly integrated GSM transceiver

designed to operate in dual-band handsets or in

single-band handsets operating at 900, 1800, and

1900 MHz frequency bands (1900 MHz performance

is not verified in production). The IC architecture

allows the RF designer to provide solutions for three

different frequency bands with very few PCB changes,

thereby providing faster time to market and reduced

development time.

The W3020 RF transceiver and W3000 PLL have

been designed in conjunction with the SC1 (radio

interface and DSP) to provide a complete GSM

cellular solution. The W3020 interfaces to the W3000

UHF high-performance PLL IC. The W3020, in

combination with the W3000, provides the transmitter,

receiver, and frequency synthesizer. Adding a power

amplifier(s), filters, and VCO modules completes the

radio channel.

The second local oscillator (LO2), comprising a buffer

for the external voltage-controlled oscillator (VCO)

and a phase-locked loop (PLL), feeds the IF portions

of both the modulator and the receiver. An external

reference source, voltage-controlled crystal oscillator

(VCXO), is divided from 13 MHz to 1 MHz through a

counter. The 1 MHz is called the comparison

frequency. The VCO frequency of 540 MHz is also

divided down to 1 MHz. Both signals are fed into a

phase detector, and the resultant error signal is fed

through an external low-pass filter to the control input

of the VCO.

The baseband modulated signal is applied to the I/Q

double-balanced mixer in a differential manner. The

±45° phase-shifted local oscillator requires no trim to

achieve the required modulation spectral mask. Also,

I/Q input signals require no dc offset calibration to

achieve high phase accuracy signal. The IF signal

outputs from the I/Q mixers are summed and brought

out to an external filter that reduces the noise that

could be intermodulated into the receive band. This

signal is then applied to the low noise up-conversion

mixer and brought to the RF output.

The RF receive and transmit mixers are driven by two

band-switchable external VCO modules and buffered

internally on the IC. The VCOs are both controlled by

a single W3000 PLL synthesizer and loop filter. Fast

band-locking is achieved using a proprietary scaling

technique integrated in the W3000 PLL.

The received signal is amplified through the low-noise

amplifier, which, combined with the preceding filter,

dominates the receiver sensitivity. The signal is then

ESD Precautions

Although protection circuitry has been designed into this device, proper precautions should be taken to avoid

exposure to electrostatic discharge (ESD) during handling and mounting. Lucent Technologies Microelectronics

Group employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing

and design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define the

model. No industry-wide standard has been adopted for CDM. However, a standard HBM (resistance = 1500 W,

capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD

threshold presented here was obtained by using these circuit parameters:

LNA

The W3020 contains two on-chip LNAs, one to operate in the GSM900 band and one to operate in the

GSM1800/1900 bands. The GSM900 operation is combined with the GSM1800 band operation in a dual-band

terminal. Only one LNA operates at a time. The two on-chip LNAs with external matching networks are 50 W

single-ended input, single-ended output type. Switching between the LNAs is determined by the band bit B and

the gain control bit G0 in the TR register, as described in the Programming Information section.

RF Mixer

The W3020 contains two mixers: one for GSM900 band operation and one for GSM1800/1900 band operation.

The RF mixers are double-balanced mixers that can be used in various modes of operation. The ac-grounded

input (pin 56) requires grounding at both the RF and the IF frequencies. If grounding is not placed close to the

device, the RF performance will be compromised. At the output, the mixer is connected to a balanced IF SAW

filter.

IF/Baseband Amplifier

gain accuracy is determined after calibration of the

32 dB amplifier.

The IF amplifier is a balanced-input/balanced-output

type and is connected to a balanced SAW filter. It

consists of three gain stages: an IF amplifier and two

sections of baseband amplifiers. The gain can be

changed in steps of 32, 16, 8, and 4 dB. The base-

band also contains a level-shifter stage to drive an

A/D converter directly. The level-shifter stage has 21

dB of gain that can be switched off. The specifications

below are for the two modes of operation.

ACTUAL = REQUESTED

REQUESTED GAIN (dB)

The gain of the IF section is programmed via the

three-wire serial bus.

Note: X , Y = relative gain accuracy.

The IF amplifier contains the 32 dB amplifier stage

and has a gain of either 0 or 32 dB. The IF amplifier is

followed by a quadrature mixer with a fixed gain of

4 dB. The first baseband amplifier (G3, G2, G6) after

the low-pass filter and demodulator has gains

selectable between 0, 4, 8, 12, 16, 20, 24, and 28 dB.

Using the other gain steps, the IF and baseband gain

can be varied by 64 dB in 4 dB steps. The second

baseband amplifier (G5, G1) has gains selectable

between 0, 4, 21, and 25 dB. The 21 dB gain step in

the second baseband amplifier section is not tested

and should therefore not be used. Figure 3 is a

diagram of the gain steps.

Figure 4. Actual Gain vs. Requested Gain

The input impedance of the IF strip will vary slightly

when the 32 dB amplifier is switched between the ON

and OFF states. We recommend that the IF strip be

matched with the 32 dB amplifier in the ON state to

provide the best match to the SAW filter when the

input level is at a minimum. The input matching

network can match the IF input directly to the SAW

filter or to 50 W.

A matching network to 50 W was chosen for the

evaluation board to allow for convenient laboratory

measurements. To keep the input impedance low and

minimize impedance variation between gain settings

of the IF stage, a resistor is shunt-connected between

the input terminals. The input network can then be

matched to the desired input impedance. (The

specified gain includes a resistor value of 500 W.) For

testing purposes, the input has been matched to 50 W,

and the gains of the IF/baseband amplifier are all

referred to a 50 W matched input impedance. The I/Q

outputs are terminated in high-impedance loads. The

gains are voltage gains and include the voltage gain in

the impedance transformation of the input matching

network. The network is illustrated in Figure 5.

To achieve the specified absolute gain accuracy, the

total gain should be calibrated at room temperature.

This would normally be part of the overall phone

calibration. Absolute gain accuracy measures the gain

change over a specified temperature range relative to

the room temperature measurement. In the GSM

system, this specification is dependent on all the RX

functional blocks and not solely on the IF strip. The

relative gain accuracy is a measure of the gain stage

accuracy over a 20 dB range (see Figure 4). Relative

Modulator

The modulator uses an indirect I/Q modulator architecture that is ideal for multiband operation. The IF

modulation improves EVM effects due to improved carrier feedthrough. The series transmit IF filters allow

improved wideband noise, which enables duplexer removal. The I/Q modulator requires no amplitude or phase

calibration to achieve high phase accuracy. The modulator can be altered between GSM900 transmit mode (TX

IF = 270 MHz) and GSM1800/1900 transmit mode (TX IF = 180 MHz) by the band bit setting in the TR register.

W3020 GSM Multiband RF Transceiver

Programming Information (continued)

The Data Word

The W3020 and W3000 chips are addressed through the bit content of the 24-bit serial word. Some words for

time-critical interactions address both W3020 and W3000 at the same time, while some words for initialization

address W3020 and W3000 separately.

The W3020 gets all of its control information via a three-wire serial bus from the baseband IC. Serial data

transfers always consist of 24 bits: 3 bits of address to select one of five control registers, and up to 21 bits of

data. The data is shifted first into a shift register and then parallel-loaded into the proper control register after the

completion of the transfer when the latch enable signal goes high. The last bit is that which immediately precedes

a low-to-high latch input transition occurring while the CLOCK input is low. Bit 24 is loaded first, and bit 1 is

loaded last. The four control registers are defined as follows:

n TR: Transmit/receive register for W3020. Contains bits for setting various transmit and receive modes, setting

receive gain, etc. It is expected that this register would be written several times during a frame.

n CONFIG: Contains bits to control various options for dc offset correction, filter-tuning, lock detect, and

overload outputs, etc. It is expected that this register would be written once at initialization and then rarely

updated. Since it is not affected by the power-on reset circuit, a write to this register should be the first

operation performed when accessing the W3020 chip. Also, it is advisable never to update the configuration

register while a critical operation is in progress.

n MAIN: Main counter and prescaler values for W3000 chip. Used to set mode and band bit functions for the

W3020 while programming the W3000.

n REF: Reference counter values for W3000. Not relevant to W3020.

a transmit burst in order to power up and lock the LO1

and LO2 VCO/PLL synthesizers and the respective

RF and IF LO buffers connecting to the modulator

circuit. The LO2 divide-by circuits remain off during

this mode. Similarly, the receive PLL settling mode is

used prior to the receive dc calibration time slot and

subsequent receive burst in order to power up and

lock the LO1 and LO2 VCO/PLL synthesizers and the

respective RF and IF LO buffers connecting to the RF

mixer and IF strip. The RF mixer can be turned on in

this mode by setting the C9 (RF mixer on during

circuits as the transmit PLL settling mode along with

the I/Q modulator and up-conversion mixer.

B: Band Select

When set low, the GSM900 transceiver circuits are

enabled and the GSM1800 transceiver circuits are

disabled. When set high, the GSM1800 transceiver

circuits are enabled and the GSM900 transceiver

circuits are disabled. The transceiver circuits that

change with the setting of the band bit B are the LNA,

the RF mixer, the receive UHF LO1 buffer, the

transmit UHF LO1 buffer, and the LO2 divider for the

modulator IF LO phase shifter circuit. The normal LO2

division factor for GSM900 is divide-by-2; for

GSM1800, the normal LO2 division factor is divide-by-

3. Note that bits T2 and T1 also affect the transmitter

LO2 division factor when set high (see Table 23 and

Table 24).

The receiver ON mode turns on all the same circuits

as the receive PLL settling mode along, with the LNA

(if enabled by the G0 bit—see Table 26), RF mixer,

and IF amplifiers and demodulator. When first going

into receive mode, a baseband LP filter tune is

performed, if requested, by setting the FTR (filter tune

request) bit high in the TR register and the C6 (filter

tune disable) bit low in the CONFIG register (see

Table 20 and Table 35, respectively, and the Low-

Pass Filter Tuning section). Next, a dc offset

calibration cycle is performed if the DS (dc correction

skip) bit is low in the TR register and the C5 (dc

correction disable) bit is low in the CONFIG register

(see Table 22 and Table 36, respectively). The default

condition is that the LNA turns off during the dc

calibration if the C2 (LNA mode during dc calibration)

bit is low in the CONFIG register (see Table 37). The

other default condition is that the RF mixer LO1 buffer

turns off during the dc calibration if the C3 (RX LO1

Table 26. G[0:6]: Digital Gain Control

Digital RX gain control with bits defined as follows:

G0: When high, enables GSM900 or GSM1800/1900 LNA according to which band is selected by band bit B.

(See Table 14.)

G4: IF gain: 0 = 0 dB, 1 = 32 dB.

G1: 0 = add 0 dB to baseband gain, 1 = add 4 dB to baseband gain in second amplifier.

G2: 0 = add 0 dB to baseband gain, 1 = add 8 dB to baseband gain in first amplifier.

G3: 0 = add 0 dB to baseband gain, 1 = add 16 dB to baseband gain in first amplifier.

G5: 0 = add 0 dB to baseband gain, 1 = add 21 dB to baseband gain in second amplifier.

G6: 0 = add 0 dB to baseband gain, 1 = add 4 dB to baseband gain in first amplifier.

The nominal demodulator mixer conversion gain is 4 dB; hence, total gain is always 4 dB higher than the DGC setting.

Voltage gain is differential assuming input matching network to 50 W source impedance. (See Table 6.)

CONFIG Register

The CONFIG register contains bits to control various options for dc offset correction, filter-tuning, lock detect,

and overload outputs, etc. It is expected that this register would be written once at initialization and then rarely

updated. Since it is not affected by the power-on reset circuit, a write to this register should be the first operation

performed when accessing the W3020 chip. Also, it is advisable never to update the configuration register while

a critical operation is in progress.

Programming Information (continued)

Filter Tune and dc Offset Correction Timing

Low-Pass Filter Tuning

The W3020 has an internal calibration to improve the accuracy of the low-pass filter bandwidth. The filter tune

operation should be performed each time supply voltage is applied to the device and after restart.

The low-pass filter tuning operation is controlled by 3 bits in the control logic:

n FTR: filter tune request, in the TR register

n C4: low-pass filter bandwidth, in the CONFIG register

n C6: filter tune disable, in the CONFIG register

If the filter tune disable bit (C6) is programmed high, the filter bandwidth is set to the programmed (nominal)

value (see Table 35), and any request for filter tuning from the FTR bit is ignored.

The accuracy of the filter bandwidth can be improved by performing a filter tune calibration. A filter tune can be

performed by setting the filter tune request (FTR) bit in the TR register high and the filter tune disable bit (C6) in

the CONFIG register low. This enables a 13/4 MHz (3.25 MHz) clock to the filter tuning state machine, which

then runs until the tuning is complete and the new filter tune values are stored. The filter tune operation itself

takes

16.5 cycles of the 3.25 MHz clock, or 5.1 ms.

The filter tune operation should be done in receive mode. The receive mode needs to be held active for at least

20 ms to allow for bias start-up.

The dc offset calibration, if requested, is performed after the filter tune is complete. The filter tune operation adds

5.1 ms to the total calibration time when requested at the same time as a dc offset calibration. If a filter tune is

requested while the MOD bits are not set to 111, only the receive bias circuitry is turned on; the rest of the

receive channel remains powered down.

31

Advance Data Sheet

December 1999

W3020 GSM Multiband RF Transceiver

Programming Information (continued)

Filter Tune and dc Offset Correction Timing (continued)

dc Offset Calibration

The dc offset calibration operation is controlled by several bits in the CONFIG and TR registers:

n DS: dc correction skip, in the TR register

n DP: dc precharge only, in the TR register

n C5: dc correction disable, in the CONFIG register

n C7: dc coarse/fine correction, in the CONFIG register

n DT: dc correction time, in the CONFIG register

When the dc correction disable bit (C5) in the CONFIG register is written high, the dc offset correction circuitry

charges to a default value, corresponding to 0 dc offset, and any request for dc offset calibration is ignored. If dc

correction disable = 0, the dc offset calibration is initiated by writing the MO bits in the TR (or MAIN) register to a

value of 111 while dc correction skip (DS) and dc precharge only (DP) are both low. As in the case of the filter

tune, start of dc offset calibration is held off for about 15 ms while the bias circuits and input clock buffer start-up.

If the FTR bit was also written high coincident with entering RX mode, a filter tune is performed first, after which

dc offset calibration begins automatically.

The dc offset calibration runs for a time determined by the dc offset correction time bits DT[0:2] in the CONFIG

register. There are three of these bits, giving the user a choice of eight different correction times.

Upon completion of the dc offset calibration, the 3.25 MHz baseband clock stops and full receive mode is

entered automatically, with the LO1 buffer and LNA (if G0 = 1) being enabled automatically.

If RX mode is entered with dc precharge only (DP = 1) set high, dc offset circuitry runs through a much shorter

calibration routine, after which normal receive mode is entered automatically. The precharge-only operation

functions much the same as the normal calibration operation in that the LO1 buffer and LNA is disabled until

completion of the precharge operation. The 15 ms bias start-up time is still incurred.

The receive circuitry conditions during dc calibration are also controlled by two other bits in the CONFIG register:

n C2: LNA on during dc calibration, when high

n C3: receive LO1 buffer on during dc, calibration when high

For both the standard dc offset calibration cycle and the dc precharge-only operation, it is possible to perform dc

offset calibration with the LNA and/or LO1 buffer on by setting the C2 and C3 bits in the CONFIG register.

Programming Example

This programming example shows how the W3020 can be programmed after power-on and how it can be

programmed prior to receive and transmit bursts. The reference register for the W3000 is initialized separately

with the reference divider ratio, as described in the W3000 data sheet.

Table 43. Initialize CONFIG Register (Reset W3020)

To reset all registers to their default state and put the device into a low-power sleep mode, one write to the

CONFIG register is necessary. This will also reset W3000 if it is connected on the same three-wire bus.

Normally, the device will be both reset and configured in the same programming as follows:

CONFIG register: reset device, set dc calibration time to max value (486 µs), set phase detector polarity for the

positive slope VCO, use high BW and coarse dc offset tune.
