RF-Links High-Power Military-Grade Microwave 80W Amplifier (9.5-11 GHz) - Manual

This ZHM-0911-G80 amplifier is a high power,
X band, Solid State Power that operates from 9.5 to
10.5 GHz. The saturated output power is 80 watts
typical at 25C. Typical small signal gain is 43 dB.
Noise figure is 6.5 dB typical at 25C. Input VSWR is
2.0:1 maximum. Output VSWR is 2.0:1 maximum. This
unit is equipped with DC switching circuitry that enables
and disables the DC-DC circuitry in 1000 nSec maximum.
Standard features include reverse polarity protection, output
short and open circuit protection, an over-temperature
alarm and an integrated DC-DC converter with
over/under voltage protection. This power amplifier
operates from a +28 Vdc power supply with a class
AB bias of typically 15.0 amps. This unit is also offered
as a +12Vdc amplifier in a smaller package. Please
contact the factory. This amplifier operates from -40C to
+65C base plate temperature. Maximum input power
with no damage is +20 dBm.

This amplifier is ideal for X Band Radar and Communication Systems
that require high reliability and high power in a rugged and com-
pact module. Standard housing size is approximately 9.25 X 11.0
X 1.50 inches. This PA needs to be heat sunk properly to keep
the base plate temperature to +65C maximum. TNC female con-
nectors are standard on the RF input and output ports. DC and
command/control signals are accessible via a DC connector. This
amplifier is environmentally sealed for operation in airborne environment.
