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
HEMT process : 0.25m gate length, via
holes through the substrate, air bridges and
electron beam gate lithography.
It is supplied in chip form.
