W3030 3 V Dual-Mode IF Cellular Receiver

parallel amplifier/demodulator sections. In the analog

second IF, there is a 40 dB amplifier followed by a

60 dB hard-limiting amplifier and an FM quadrature

detector (noncoherent discriminator). The signal path

between the 40 dB and 60 dB amplifier stages is

brought off-chip for external filtering purposes. In

digital mode, an AGC amplifier provides gain between

10 dB and 80 dB. The digital signal is demodulated in

double-balanced mixers that are fed with an external

local oscillator (LO) signal. The external LO passes

through a divide-by-four counter to provide the final IF

LO frequency. This architecture greatly reduces the

possibility of feedback of the external LO signal to the

IF input, which would cause dc offsets at the I & Q

outputs. This circuit also provides a 90° phase shift of

the LO that is independent of duty cycle. The resulting

I & Q differential pairs can be level-shifted using the

VCM input pin, providing flexibility in interfacing to

digital processing ICs.

Description

The W3030 is a monolithic integrated circuit that

provides most of the receive path functions required

to meet the IS-136 (and IS-54) standard. The W3030

converts FM or digitally modulated IF carriers up to

200 MHz and provides required IF gain and separate

baseband detectors for the two modulation modes.

The W3030 is organized into three subfunctions (see

Figure 2):

1. First IF mixer/amplifier

2. Analog second IF

3. Digital second IF sections

(Note that the electrical specification tables

correspond to each subfunction.)

Each section has a buffered output to allow for

external filtering, which also provides flexibility in

system architecture selection. The first IF mixer

section provides 30 dB of fixed voltage conversion

gain (power gain = 17 dB). The first IF mixer also

performs down-conversion to the 0.2 MHz—2.0 MHz

range, which allows the use of inexpensive ceramic

filters at two points in the signal path. In the second IF

section, the signal path may be split between two

A pair of logic inputs allows the device to be put into a

powerdown mode and one of two partially enabled

modes (analog or digital only), or a fully enabled

mode, allowing the use of analog RSSI while in digital

receive mode.

Handling 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 protection 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:

W3030 3 V Dual-Mode IF Cellular Receiver

Quadrature Detector

RSSI

The RSSI output provides a voltage level that is

proportional to the amount of signal present in the

analog second IF section. This voltage level is

generated internally by summing of the signal current

at different points in the 40 dB and 60 dB IF chains.

The amount of loss between the 40 dB and 60 dB

sections will affect the RSSI linearity. Figure 3

contains two traces of RSSI voltage versus IF input

power. One trace is with only the filter loss between

the 40 dB and 60 dB amplifiers. The second trace is

with a filter and a resistor, to give a total loss of

5.6 dB. The figure indicates a nonlinearity around the

–75 dBm input level. This nonlinearity occurs because

the 60 dB amplifier chain enters compression, causing

less RSSI output. Eventually, as the input signal

increases, the 40 dB amplifier will begin to contribute

to the total RSSI.

Figure 4 is a simplified schematic of the quadrature

detector of the W3030. The quadrature detector circuit

is similar to a mixer; but, instead of mixing two

different frequencies, it multiplies two signals of the

same frequency that are phase-shifted versions of

each other. Multiplying the phase-shifted with the

unshifted signals produces the audio portion of the FM

signal.

CS

IFAOUT

AUDIO

L

CP

R

QUAD

CBYPASS

It was determined that 6 dB of interstage loss

produces the optimal RSSI response. Most ceramic

filters have less than 6 dB insertion loss. Therefore,

some additional loss must be inserted in addition to

the filter. The simplest way is to use a resistor in

series with the filter. This method will cause a

mismatch to the filter and may distort its passband

response. An L or T configuration may be necessary

to provide the required loss without mismatching the

filter.

Figure 4. Quadrature Detector

Before the IF signal is differentially applied to the

multiplier, the signal is passed through a limiter stage

to produce a constant amplitude signal. The same

signal is brought out single-ended to pin 4, IFAOUT.

The signal at IFAOUT is passed through a phase-

shifting network (CS + CP + L + R). The phase-shifted

signal is applied back to the lower portion of the

multiplier at pin 3, QUAD. The parallel L/C resonant

circuit provides frequency selective filtering at the IF

frequency. The L/C tank must be ac-grounded at the

IF frequency through a dc blocking capacitor

(CBYPASS).

Because information in an FM signal is contained in

the deviation from the center frequency, the design of

the resonant bandpass circuit is very important,

particularly the load Q. A higher-loaded Q for a given

deviation will produce a larger output signal than a

lower Q circuit. However, a high Q circuit will permit

only a limited amount of deviation from center

frequency before distortion occurs.

The W3030 evaluation board is designed with a 450 kHz IF frequency, as shown in our example. The Q of the

tank circuit is set to 10 by the external resistor.

Quad Tank S-Curves

One method of determining if the Q of the tank is too large or too small is to produce an S-curve of the quad

tank. An S-curve is a plot of the dc audio output voltage versus IF input frequency. With small deviations from

center frequency, there is a proportional change in the dc audio output voltage. The overall linearity of the curve

is determined by the Q of the tank circuit; therefore, the Q determines how much deviation is allowed before

distortion of the audio signal occurs. The L/C tank circuit has a shunt resistor to set the Q of the tank. The

procedure to produce these plots is as follows:

1. Remove the 450 kHz IF filter and drive the input of the limiting amplifier with a signal generator capable of

FM modulation.

2. Apply FM modulation and adjust the tank capacitor for maximum audio out and minimal distortion.

3. Remove the FM modulation and sweep the IF frequency above and below center frequency while monitoring

the dc voltage at the audio output.

The following S-curves were produced with the value of the quad tank resistor varied from 18 kW, to 30 kW, to

removing the resistor. The resistor value of 33 kW, which corresponds to a Q of 10, was chosen as the optimal

resistor value.
