Abstract
The potential of HEMT oscillators as signal sources for millimeter wave systems was investigated. Free running, varactor tuned and subharmonic injection locked oscillators, based on 0.15 mu m AlGaAs/InGaAs/GaAs HEMTs have been developed at millimeter wave frequencies from 35 to 94 GHz. Integration of these oscillators with amplifiers in a coplanar environment has been demonstrated.
