CHA5292a
37-40GHz Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA5292a is a high gain four-stage
monolithic medium 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, 0.15µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
