Abstract :
A CPW 2 GHz 3-port MESFET oscillator was designed with an electro-optic modulator application in mind. The oscillator has a self-biased gate. The source or drain ports can be used for external injection-locking. The frequency of oscillation, as well as the output power at the fundamental and first two harmonics were analyzed using a nonlinear device model and a harmonic balance technique. Comparison with measured results on a hybrid CPW oscillator fabricated on a Duroid substrate are presented.
