RF-Links Military-Grade 30W High-Power Amplifier (500 MHz-2.5 GHz) - Manual

ZHM50-250/30
MIL Grade High Power Amplifier
This is a high power, broadband, gallium nitride (GaN) RF amplifier that
operates from 0.5 to 2.5 GHz. 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 has a
typical P1dB of 20 watts at room temperature. Saturated output power
across the band is typically 25 to 30 watts. Noise figure at room
temperature is 7.5 dB typical. This amplifier offers a typical gain of 55 dB
with a typical gain flatness of ± 2.5 dB.
