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

Chip Biasing options
Internal DC schematic
This chip is self-biased, and flexibility is provided by the access to positive Vg.
The internal DC electrical schematic is given in order to use these pads in a safe way.
Absolute recommandations:
N°1 : Do not exceed Vds = 3.5 Volt ( Vds: internal Drain to Source voltage ).
N°2 : Do not bias in such a way that Vgs* becomes positive. (Vgs :internal Gate to Source voltage )
