Functional Diagram
General Description
The HMC712LP3CE 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 first
varying Vctrl1 of the 1st attenuation stage from -3V
to 0V with Vctrl2 fixed at -3V. The control voltage of
the 2nd attenuation stage, Vctrl2, should then be
varied from -3V to 0V, with Vctrl1 fixed at 0V. The
HMC712LP3CE is housed in a RoHS compliant
3x3 mm QFN leadless package
However, 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.
