UMS CHA4092REF

CHA4092
20-30GHz High Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA4092 is a high gain broadband threestage balanced monolithic power amplifier. It is
designed for a wide range of applications, from
military to commercial communication systems.
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.
