CHA2190
RoHS COMPLIANT
20-30GHz Low Noise Amplifier
self biased
GaAs Monolithic Microwave IC
Description
The circuit is a two-stages self biased 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.
