ABSTRACT:
A circuit for biasing a gallium arsenide (GaAs) power amplifier includes a reference voltage generator circuit implemented in a gallium arsenide (GaAs) material system, a field effect transistor (FET) bias circuit implemented in the gallium arsenide material system and adapted to receive an output of the reference voltage generator circuit and adapted to provide an output to a radio frequency (RF) amplifier stage.
