GENERAL DESCRIPTION
The ADL5387 is a broadband quadrature I/Q demodulator that
covers an RF/IF input frequency range from 30 MHz to 2 GHz.
With a NF = 13.2 dB, IP1dB = 12.7 dBm, and IIP3 = 32 dBm @
450 MHz, the ADL5387 demodulator offers outstanding dynamic
range suitable for the demanding infrastructure direct-conversion
requirements. The differential RF/IF inputs provide a well-
behaved broadband input impedance of 50 Ω and are best
driven from a 1:1 balun for optimum performance.
The fully balanced design minimizes effects from second-order
distortion. The leakage from the LO port to the RF port is
<−70 dBc. Differential dc-offsets at the I and Q outputs are
<10 m V. Both of these factors contribute to the excellent IIP2
specifications > 60 dBm.
The ADL5387 operates off a single 4.75 V to 5.25 V supply. The
supply current is adjustable with an external resistor from the
BIAS pin to ground.
Ultrabroadband operation is achieved with a divide-by-2 method
for local oscillator (LO) quadrature generation. Over a wide
range of LO levels, excellent demodulation accuracy is
achieved with amplitude and phase balances ~0.05 dB and
~0.4°, respectively. The demodulated in-phase (I) and
quadrature (Q) differential outputs are fully buffered and
provide a voltage conversion gain of >4 dB. The buffered
baseband outputs are capable of driving a 2 V p-p differential
signal into 200 Ω.
The ADL5387 is fabricated using the Analog Devices, Inc.
advanced silicon-germanium bipolar process and is available in
a 24-lead exposed paddle LFCSP.

ADL5387
Data Sheet
CIRCUIT DESCRIPTION
The ADL5387 can be divided into five sections: the local
oscillator (LO) interface, the RF voltage-to-current (V-to-I)
converter, the mixers, the differential emitter follower outputs,
and the bias circuit. A detailed block diagram of the device is
shown in Figure 45.
V-TO-I CONVERTER
The differential RF input signal is applied to a resistively
degenerated common base stage, which converts the differential
input voltage to output currents. The output currents then
modulate the two half-frequency LO carriers in the mixer stage.
BIAS
MIXERS
The ADL5387 has two double-balanced mixers: one for the
in-phase channel (I channel) and one for the quadrature channel
(Q channel). These mixers are based on the Gilbert cell design
of four cross-connected transistors. The output currents from
the two mixers are summed together in the resistive loads that
then feed into the subsequent emitter follower buffers.

ILO

PHASE SPLITTER
RFIN
The output emitter followers drive the differential I and Q
signals off-chip. The output impedance is set by on-chip 25 Ω
series resistors that yield a 50 Ω differential output impedance
for each baseband port. The fixed output impedance forms a
voltage divider with the load impedance that reduces the effective
gain. For example, a 500 Ω differential load has 1 dB lower
effective gain than a high (10 kΩ) differential load impedance.

QHI
QLO
Figure 45. Block Diagram
BIAS CIRCUIT
The LO interface generates two LO signals at 90° of phase
difference to drive two mixers in quadrature. RF signals are
converted into currents by the V-to-I converters that feed into
the two mixers. The differential I and Q outputs of the mixers
are buffered via emitter followers. Reference currents to each
section are generated by the bias circuit. A detailed description
of each section follows.
A band gap reference circuit generates the proportional-to-
absolute temperature (PTAT) as well as temperature-independent
reference currents used by different sections. The mixer current
can be reduced via an external resistor between the BIAS pin
and ground. When the BIAS pin is open, the mixer runs at
maximum current and hence the greatest dynamic range. The
mixer current can be reduced by placing a resistance to ground;
therefore, reducing overall power consumption, noise figure,
and IIP3. The effect on each of these parameters is shown in
Figure 10, Figure 13, and Figure 14.
LO INTERFACE
The LO interface consists of a buffer amplifier followed by a
frequency divider that generate two carriers at half the input
frequency and in quadrature with each other. Each carrier is
then amplified and amplitude-limited to drive the double-
balanced mixers.

1000pF
POWER SUPPLY
1000pF
The nominal voltage supply for the ADL5387 is 5 V and is
applied to the VPA, VPB, VPL, and VPX pins. Ground should
be connected to the COM, CML, and CMRF pins. Each of
the supply pins should be decoupled using two capacitors;
recommended capacitor values are 100 pF and 0.1 µF.
Figure 46. Single-Ended LO Drive
The recommended LO drive level is between −6 dBm and
+6 dBm. For operation below 50 MHz, a minimum LO drive
level of 0 dBm should be used. The LO frequency at the input to
the device should be twice that of the desired LO frequency at
the mixer core. The applied LO frequency range is between
60 MHz and 4 GHz.
LOCAL OSCILLATOR (LO) INPUT
The LO port is driven in a single-ended manner. The LO signal
must be ac-coupled via a 1000 pF capacitor directly into LOIP,
and LOIN is ac-coupled to ground also using a 1000 pF capacitor.
The LO port is designed for a broadband 50 Ω match and
therefore exhibits excellent return loss from 60 MHz to 4 GHz.
The LO return loss can be seen in Figure 20. Figure 46 shows
the LO input configuration.

Data Sheet
The differential RF port return loss has been characterized as
shown in Figure 49.
RF INPUT
The RF inputs have a differential input impedance of
–10
approximately 50 Ω. For optimum performance, the RF port
should be driven differentially through a balun. The recommended
balun is M/A-COM ETC1-1-13. The RF inputs to the device
should be ac-coupled with 1000 pF capacitors. Ground-referenced
choke inductors must also be connected to RFIP and RFIN
(recommended value = 120 nH, Coilcraft 0402CS-R12XJL) for
appropriate biasing. Several important aspects must be taken
into account when selecting an appropriate choke inductor for
this application. First, the inductor must be able to handle the
approximately 40 mA of standing dc current being delivered
from each of the RF input pins (RFIP, RFIN). (The suggested
0402 inductor has a 50 mA current rating). The purpose of the
choke inductors is to provide a very low resistance dc path to
ground and high ac impedance at the RF frequency so as not to
affect the RF input impedance. A choke inductor that has a self-
resonant frequency greater than the RF input frequency ensures
that the choke is still looking inductive and therefore has a more
predictable ac impedance (jωL) at the RF frequency. Figure 48
shows the RF input configuration.

BASEBAND OUTPUTS
The baseband outputs QHI, QLO, IHI, and ILO are fixed
impedance ports. Each baseband pair has a 50 Ω differential
output impedance. The outputs can be presented with differential
loads as low as 200 Ω (with some degradation in linearity and
gain) or high impedance differential loads (500 Ω or greater
impedance yields the same excellent linearity) that is typical of
an ADC. The TCM9-1 9:1 balun converts the differential IF
output to single-ended. When loaded with 50 Ω, this balun
presents a 450 Ω load to the device. The typical maximum
linear voltage swing for these outputs is 2 V p-p differential.
The bias level on these pins is equal to VPOS − 2.8 V. The
output 3 dB bandwidth is 240 MHz. Figure 50 shows the
baseband output configuration.

EVM is a measure used to quantify the performance of a digital
radio transmitter or receiver. A signal received by a receiver
would have all constellation points at the ideal locations; however,
various imperfections in the implementation (such as carrier
leakage, phase noise, and quadrature error) cause the actual
constellation points to deviate from the ideal locations.

The ADL5387 shows excellent EVM performance for various
modulation schemes. Figure 51 shows typical EVM performance
over input power range for a point-to-point application with
16 QAM modulation schemes and zero-IF baseband. The
differential dc offsets on the ADL5387 are in the order of a
few mV. However, ac coupling the baseband outputs with 10 µF
capacitors helps to eliminate dc offsets and enhances EVM
performance. With a 10 MHz BW signal, 10 µF ac coupling
capacitors with the 500 Ω differential load results in a high-pass
corner frequency of ~64 Hz which absorbs an insignificant
amount of modulated signal energy from the baseband signal.
By using ac coupling capacitors at the baseband outputs, the dc
offset effects, which can limit dynamic range at low input power
levels, can be eliminated.

Figure 54. Illustration of the Image Problem
LOW IF IMAGE REJECTION
EXAMPLE BASEBAND INTERFACE
The image rejection ratio is the ratio of the intermediate
frequency (IF) signal level produced by the desired input
frequency to that produced by the image frequency. The image
rejection ratio is expressed in decibels. Appropriate image
rejection is critical because the image power can be much
higher than that of the desired signal, thereby plaguing the
down conversion process. Figure 54 illustrates the image
problem. If the upper sideband (lower sideband) is the desired
band, a 90° shift to the Q channel (I channel) cancels the image
at the lower sideband (upper sideband).
In most direct conversion receiver designs, it is desirable to
select a wanted carrier within a specified band. The desired
channel can be demodulated by tuning the LO to the appropriate
carrier frequency. If the desired RF band contains multiple
carriers of interest, the adjacent carriers would also be down
converted to a lower IF frequency. These adjacent carriers can
be problematic if they are large relative to the wanted carrier as
they can overdrive the baseband signal detection circuitry. As a
result, it is often necessary to insert a filter to provide sufficient
rejection of the adjacent carriers.
Figure 55 shows the excellent image rejection capabilities of the
ADL5387 for low IF applications, such as CDMA2000. The
ADL5387 exhibits image rejection greater than 45 dB over the
broad frequency range for an IF = 1.23 MHz.

It is necessary to consider the overall source and load impedance
presented by the ADL5387 and ADC input to design the filter
network. The differential baseband output impedance of the
ADL5387 is 50 Ω. The ADL5387 is designed to drive a high
impedance ADC input. It may be desirable to terminate the
ADC input down to lower impedance by using a terminating
resistor, such as 500 Ω. The terminating resistor helps to better
define the input impedance at the ADC input. The order and
type of filter network depends on the desired high frequency
rejection required, pass-band ripple, and group delay. Filter
design tables provide outlines for various filter types and orders,
illustrating the normalized inductor and capacitor values for a
1 Hz cutoff frequency and 1 Ω load. After scaling the normalized
prototype element values by the actual desired cut-off frequency
and load impedance, the series reactance elements are halved to
realize the final balanced filter network component values.

As an example, a second-order, Butterworth, low-pass filter
design is shown in Figure 56 where the differential load impedance
is 500 Ω, and the source impedance of the ADL5387 is 50 Ω.
The normalized series inductor value for the 10-to-1, load-to-
source impedance ratio is 0.074 H, and the normalized shunt
capacitor is 14.814 F. For a 10.9 MHz cutoff frequency, the
single-ended equivalent circuit consists of a 0.54 µH series
inductor followed by a 433 pF shunt capacitor.

Figure 56. Second-Order, Butterworth, Low-Pass Filter Design Example
A complete design example is shown in Figure 59. A sixth-order
Butterworth differential filter having a 1.9 MHz corner frequency
interfaces the output of the ADL5387 to that of an ADC input.
The 500 Ω load resistor defines the input impedance of the
ADC. The filter adheres to typical direct conversion WCDMA
applications, where 1.92 MHz away from the carrier IF frequency,
1 dB of rejection is desired and 2.7 MHz away 10 dB of rejection
is desired.

setups used extensively for the ADL5387. The setup shown in
Figure 62 was used to do the bulk of the testing and used sinusoidal
signals on both the LO and RF inputs. An automated Agilent-
VEE program was used to control the equipment over the IEEE
bus. This setup was used to measure gain, IP1dB, IIP2, IIP3, I/Q
gain match, and quadrature error. The ADL5387 characterization
board had a 9-to-1 impedance transformer on each of the
differential baseband ports to do the differential-to-single-
ended conversion.
10 MHz. For the case where a blocker was applied, the output
blocker was at 15 MHz baseband frequency. Note that great care
must be taken when measuring NF in the presence of a blocker.
The RF blocker generator must be filtered to prevent its noise
(which increases with increasing generator output power) from
swamping the noise contribution of the ADL5387. At least
30 dB of attention at the RF and image frequencies is desired.
For example, with a 2xLO of 1848 MHz applied to the ADL5387,
the internal 1xLO is 924 MHz. To obtain a 15 MHz output
blocker signal, the RF blocker generator is set to 939 MHz and
the filters tuned such that there is at least 30 dB of attenuation
from the generator at both the desired RF frequency (934 MHz)
and the image RF frequency (914 MHz). Finally, the blocker
must be removed from the output (by the 10 MHz low-pass
filter) to prevent the blocker from swamping the analyzer.
The two setups shown in Figure 60 and Figure 61 were used
for making NF measurements. Figure 60 shows the setup for
measuring NF with no blocker signal applied while Figure 61
was used to measure NF in the presence of a blocker. For both
setups, the noise was measured at a baseband frequency of

R4, R5,
R9 to R16
Single-Ended Baseband Output Path. This is the default configuration of the evaluation
board. R14 to R16 and R4, R5, and R13 are populated for appropriate balun interface.
R9, R10 and R11, R12 are not populated. Baseband outputs are taken from QHI and IHI.
R4, R5, R13 to R16 = 0 Ω (0402),
R9 to R12 = Open
The user can reconfigure the board to use full differential baseband outputs. R9 to R12
provide a means to bypass the 9:1 TCM9-1 transformer to allow for differential baseband
outputs. Access the differential baseband signals by populating R9 to R12 with 0 Ω and
not populating R4, R5, R13 to R16. This way the transformer does not need to be removed.
The baseband outputs are taken from the SMAs of Q_HI, Q_LO, I_HI, and I_LO.
L1, L2,
R7, R8
Input Biasing. Inductance and resistance sets the input biasing of the common base
input stage. Default value is 120 nH for operation above 50 MHz. For operation down to
30 MHz, L1 and L2 should be changed to 680 nH.
L1, L2 = 120 nH (0402)
R7, R8 = 0 Ω (0402)
T2, T3
IF Output Interface. TCM9-1 converts a differential high impedance IF output to a single- T2, T3 = TCM9-1, 9:1 (Mini-Circuits)
