Typical Applications
The HMC998APM5E is ideal for:
• Test Instrumentation
• Military & Space
• Fiber optics
General Description
The HMC998APM5E is a GaAs pHEMT MMIC
Distributed Power Amplier which operates from DC
to 22 GHz. The amplier provides +15 dB of gain,
+42 dBm output IP3, and +32 dBm of output power
at 1dB gain compression while requiring only 500mA
from a +15V supply. The HMC998APM5E exhibits a
slightly positive gain slope from 3 to 17 GHz making
it ideal for military and space and test equipment
applications. The HMC998APM5E amplier I/Os
are internally matched to 50 Ohms and is housed in
a RoHS compliant, 5x5 mm leadless QFN surface
mount package.

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 vias should be used to con-
nect the top and bottom ground planes, including
the grounds directly beneath the ground paddle, to
provide for adequate electrical and thermal conduc-
tion. Use of a heatsink on the bottom side of the
PCB is recommended.
