VARIABLE GAIN AMPLIFIER
5 - 12 GHz
Functional Diagram
The HMC996LP4E is a GaAs PHEMT MMIC analog
variable gain amplier and / or driver amplier which
operates between 5 and 12 GHz. Ideal for microwave
radio applications, the amplier provides up to 18.5
dB of gain, output P1dB of up to +23 dBm, and up
to +34 dBm of output IP3 at maximum gain, while
requiring only 170 mA from a +5V supply. Gain
control voltage pin (Vctrl) is provided to allow variable
gain control up to 22 dB. Gain atness is excellent
making the HMC996LP4E ideal for EW, ECM and
radar applications. The HMC996LP4E is housed in
a RoHS compliant 4 x 4 mm QFN leadless package
and is compatible with high volume surface mount
manufacturing.

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
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 Hit-
tite upon request.
