CHA2295
6 - 11GHz Buffer Splitter Amplifier
GaAs Monolithic Microwave IC
Description
OUT 1
The CHA2295 is a broadband buffer splitter
three-stage monolithic 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.

IN
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.
