RF-Links Military-Grade 120W High-Power Amplifier (20-525 MHz) - Manual

ZHM0.2-525/120
MIL Grade High Power Amplifier
This is a high power, broadband, Gallium Nitride (GaN) RF amplifier that
operates from 20 MHz to 520 MHz.
This PA is ideal for broadband military platforms as well as commercial
applications because it is robust and offers high power over a multi-octave
bandwidth. This amplifier was designed for broad band jamming and
communication systems platforms. This amplifier operates with a base
plate temperature of 85C with no degradation in the MTBF for the GaN
devices inside. It is packaged in a modular housing that is approximately
3.4" (width) by 6.4" (long) by 1.0" (height). This amplifier has a typical
P3dB of 100-125
watts at room temperature. Noise figure at room temperature is 10.0 dB
typical. This amplifier offers a typical gain of 58 dB with a typical gain
flatness of ± 2.0 dB. The power and gain flatness across the band is
extremely flat for the bandwidth. Input VSWR is 2.0:1 maximum. Class AB
quiescent current is ~2.0 amps typical employing a +28 Vdc supply.
