CHA5293a
RoHS COMPLIANT
17-24GHz High Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA5293a is a high gain three-stage
monolithic high power amplifier. It is designed
for a wide range of applications, from military to
commercial
communication
systems. The
backside of the chip is both RF and DC grounds.
This helps simplify the assembly process.
The circuit is manufactured with a PM-HEMT
process, 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
