CHA2091
36-40GHz Low Noise Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2091 is a two-stage wide band
monolithic low noise amplifier.
The circuit is manufactured with a standard
HEMT process : 0.25µm gate length, via
holes through the substrate, air bridges
and electron beam gate lithography.
It is supplied in chip form.
