20-30GHz Low Noise Amplifier

GaAs Monolithic Microwave IC

Description

The CHA2093 is a two-stage wide band

monolithic low noise amplifier.

The circuit is manufactured with a standard

pHEMT process: 0.25µm gate length, via

holes through the substrate, air bridges

and electron beam gate lithography.

It is supplied in chip form.
