Abstract :
A millimeter-wave GaAs HEMT MMIC oscillator at 29 GHz with a new linear and nonlinear HEMT model has been developed which is able to describe the single side source grounded configuration. The resonance frequency and output power has been predicted by the nonlinear simulation. The output power of the oscillator is greater than 6 dBm and with different dielectric resonators (DR´s) the oscillator can lock to resonance frequencies from 26.5 to 29.5 GHz. The active device is a AlGaAs-GaAs HEMT with a gatelength of 0.2 μm and a gatewidth of 2×40 μm
