CHA4220-QGG
0.5-20GHz Driver
GaAs Monolithic Microwave IC
Description
The CHA4220-QGG is a distributed Driver
Amplifier that operates between 0.5 and
20GHz.
It is designed for a wide range of
applications, such as electronic warfare, X
and Ku Point to Point Radio, and test
instrumentation.
The circuit is manufactured using a 0.25µm
gate length power pHEMT process, with via
holes through the substrate, air bridges and
optical gate lithography.
The part is supplied as 5x5 QFN package
with input and output RF accesses matched
to 50 ohms.
