CHA6558-99F
RoHS COMPLIANT
28-32GHz HPA 2W
GaAs Monolithic Microwave IC
Description
The CHA6558-99F is a monolithic four
stages GaAs high power amplifier, designed
for Ka-Band applications.
The circuit is dedicated to telecommunication
and VSAT, SATCOM and is also well suited
for a wide range of microwave applications
and systems.
It is developed on a robust 0.15µm gate
length pHEMT process, via holes through the
substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
