GENERAL DESCRIPTION
The ADL5382 is a broadband quadrature I-Q demodulator that
covers an RF input frequency range from 700 MHz to 2.7 GHz.
With a NF = 14 dB, IP1dB = 14.7 dBm, and IIP3 = 33.5 dBm at
900 MHz, the ADL5382 demodulator offers outstanding dynamic
range suitable for the demanding infrastructure direct-conversion
requirements. The differential RF 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
<−65 dBc. Differential dc offsets at the I and Q outputs are typically
<10 mV. Both of these factors contribute to the excellent IIP2
specifications which is >60 dBm.
The ADL5382 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.
Excellent demodulation accuracy is achieved with amplitude and
phase balances ~0.05 dB and ~0.2°, 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 ADL5382 is fabricated using the Analog Devices, Inc.,
advanced Silicon-Germanium bipolar process and is available
in a 24-lead exposed paddle LFCSP.

ADL5382
CIRCUIT DESCRIPTION
The ADL5382 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 39.
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 ADL5382 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.

RFIN
The output emitter followers drive the differential I and Q
signals off-chip. The output impedance is set by on-chip 25 ꢀ
series resistors that yield a 50 ꢀ 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 ꢀ differential load has 1 dB lower
effective gain than a high (10 kꢀ) differential load impedance.

Figure 39. 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 therefore 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 polyphase quadrature splitter
followed by a limiting amplifier. The LO input impedance is set
by the polyphase, which splits the LO signal into two differential
signals in quadrature. Each quadrature LO signal then passes
through a limiting amplifier that provides the mixer with a
limited drive signal. For optimal performance, the LO inputs
must be driven differentially.

APPLICATIONS INFORMATION
BASIC CONNECTIONS
LOCAL OSCILLATOR (LO) INPUT
Figure 41 shows the basic connections schematic for the ADL5382.
For optimum performance, the LO port should be driven
differentially through a balun. The recommended balun is
the M/A-COM ETC1-1-13. The LO inputs to the device should
be ac-coupled with 1000 pF capacitors. The LO port is designed
for a broadband 50 ꢀ match from 700 MHz to 2.7 GHz. The
LO return loss can be seen in Figure 20. Figure 40 shows the LO
input configuration.
POWER SUPPLY
The nominal voltage supply for the ADL5382 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. The exposed
paddle on the underside of the package should also be soldered
to a low thermal and electrical impedance ground plane. If the
ground plane spans multiple layers on the circuit board, these
layers should be stitched together with nine vias under the
exposed paddle. The Application Note AN-772 discusses the
thermal and electrical grounding of the LFCSP in detail. Each
of the supply pins should be decoupled using two capacitors;
recommended capacitor values are 100 pF and 0.1 μF.

The differential RF port return loss is characterized as shown in
Figure 43.
RF INPUT
The RF inputs have a differential input impedance of
–10
approximately 50 ꢀ. For optimum performance, the RF port
should be driven differentially through a balun. The recommended
balun is the 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 (the
recommended value is 33 nH, Coilcraft 0603CS-33NX) 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
0603 inductor has a 600 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 42
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 ꢀ differential
output impedance. The outputs can be presented with differential
loads as low as 200 ꢀ (with some degradation in gain) or high
impedance differential loads (500 ꢀ 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 ꢀ, this balun presents a 450 ꢀ
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
370 MHz. Figure 44 shows the baseband output configuration.

ERROR VECTOR MAGNITUDE (EVM) PERFORMANCE
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 magnitude
imbalance, noise floor, and phase imbalance) cause the actual
constellation points to deviate from the ideal locations.

Figure 46 shows the zero-IF EVM performance of a 10 MHz
IEEE 802.16e WiMAX signal through the ADL5382. The
differential dc offsets on the ADL5382 are in the order of a few
millivolts. However, ac coupling the baseband outputs with
10 μF capacitors eliminates dc offsets and enhances EVM
performance. With a 10 MHz BW signal, 10 μF ac coupling
capacitors with the 500 ꢀ 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 48. Illustration of the Image Problem
EXAMPLE BASEBAND INTERFACE
LOW IF IMAGE REJECTION
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.
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 48 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). Phase and gain balance between I and Q channels
are critical for high levels of image rejection.
It is necessary to consider the overall source and load impedance
presented by the ADL5382 and ADC input to design the filter
network. The differential baseband output impedance of the
ADL5382 is 50 ꢀ. The ADL5382 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 ꢀ. The terminating resistor helps to better
define the input impedance at the ADC input at the cost of a
slightly reduced gain (see the Circuit Description section for
details on the emitter-follower output loading effects). 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 ꢀ 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.
Figure 49 shows the excellent image rejection capabilities of
the ADL5382 for low IF applications, such as W-CDMA. The
ADL5382 exhibits image rejection greater than 45 dB over a
broad frequency range.

As an example, a second-order Butterworth, low-pass filter
design is shown in Figure 50 where the differential load impedance
is 500 ꢀ and the source impedance of the ADL5382 is 50 ꢀ. 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 51 and Figure 52 show the measured frequency response

A complete design example is shown in Figure 53. A sixth-order
Butterworth differential filter having a 1.9 MHz corner frequency
interfaces the output of the ADL5382 to that of an ADC input.
The 500 ꢀ load resistor defines the input impedance of the
ADC. The filter adheres to typical direct conversion W-CDMA
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.

As the load impedance of the filter increases, the filter design
becomes more challenging in terms of meeting the required
rejection and pass band specifications. In the previous W-
CDMA example, the 500 ꢀ load impedance resulted in the
design of a sixth-order filter that has relatively large inductor
values and small capacitor values. If the load impedance is 200 ꢀ,
the filter design becomes much more manageable. As shown in
Figure 54, the resultant inductor and capacitor values become
much more practical.

CHARACTERIZATION SETUPS
Figure 57 to Figure 59 show the general characterization bench
setups used extensively for the ADL5382. The setup shown in
Figure 59 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 ADL5382 characterization
board had a 9-to-1 impedance transformer on each of the
differential baseband ports to do the differential-to-single-
ended conversion, which presented a 450 ꢀ differential load to
each baseband port, when interfaced with 50 ꢀ test equipment.
For all measurements of the ADL5382, the loss of the RF input
balun (the M/A-COM ETC1-1-13 was used on RF input during
characterization) was de-embedded.
The two setups shown in Figure 57 and Figure 58 were used for
making NF measurements. Figure 57 shows the setup for
measuring NF with no blocker signal applied while Figure 58
was used to measure NF in the presence of a blocker. For both
setups, the noise was measured at a baseband frequency of
10 MHz. For the case where a blocker was applied, the output
blocker was at a 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 ADL5382. At least
30 dB of attention at the RF and image frequencies is desired.
For example, assume a 915 MHz signal applied to the LO inputs of
the ADL5382. To obtain a 15 MHz output blocker signal, the RF
blocker generator is set to 930 MHz and the filters tuned such
that there is at least 30 dB of attenuation from the generator at
both the desired RF frequency (925 MHz) and the image RF
frequency (905 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.

Not applicable
VPOS, GND
R1, R3, R6
Power Supply and Ground Vector Pins.
Power Supply Decoupling. Shorts or power supply decoupling resistors.
These capacitors provide the required decoupling up to 2.7 GHz.
R1, R3, R6 = 0 Ω (0603)
C1, C2, C3,
C4, C8, C9
C2, C4, C8 = 100 pF (0402)
C1, C3, C9 = 0.1 μF (0603)
C6, C7,
C10, C11
AC Coupling Capacitors. These capacitors provide the required ac coupling from
700 MHz to 2.7 GHz.
C6, C10, C11 = 1000 pF (0402)
C7 = open
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. The default value is 33 nH.
L1, L2 = 33 nH (0603CS-33NX,
Coilcraft)
R7, R8 = 0 Ω (0402)
T2, T3
IF Output Interface. TCM9-1 converts a differential high impedance IF output to a single-
ended output. When loaded with 50 Ω, this balun presents a 450 Ω load to the device.
The center tap can be decoupled through a capacitor to ground.
T2, T3 = TCM9-1, 9:1
(Mini-Circuits)
C12, C13
Decoupling Capacitors. C12 and C13 are the decoupling capacitors used to reject noise
on the center tap of the TCM9-1.
C12, C13 = 0.1 μF (0402)
T4 = ETC1-1-13, 1:1 (M/A-COM)
T1 = ETC1-1-13, 1:1 (M/A-COM)
