Typical Applications
The HMC712ALP3CE is ideal for:
• Point-to-Point Radio
• VSAT Radio
• Test Instrumentation
• Microwave Sensors
• Military, ECM & Radar
The HMC712ALP3CE is an absorptive Voltage Var-
iable Attenuator (VVA) which operates from 5 - 26.5
GHz and is ideal in designs where an analog DC
control signal must be used to control RF signal
levels over a 28 dB amplitude range. It features two
shunt-type attenuators which are controlled by two
analog voltages, Vctrl1 and Vctrl2. Optimum linearity
performance of the attenuator is achieved by rst
varying Vctrl1 of the 1st attenuation stage from -5V
to 0V with Vctrl2 xed at -5V. The control voltage of
the 2nd attenuation stage, Vctrl2, should then be
varied from -5V to 0V, with Vctrl1 xed at 0V. The
HMC712ALP3CE is housed in a RoHS compliant
3x3 mm QFN leadless package
Furthermore, if the Vctrl1 and Vctrl2 pins are
connected together it is possible to achieve the
full analog attenuation range with only a small
degradation in input IP3 performance. Applications
include AGC circuits and temperature compensation
of multiple gain stages in microwave point-to-point and
VSAT radios.

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Analog Devices upon request.
