This paper is concerned with the design and simulation of fixed frequency microwaveoscillator. Scattering parameters of the active device (MESFET-Afm02n8b) are used todesign and synthesize the oscillator. The computer aided design package (MicrowaveOffice 2000 version 3.22) is employed to optimize oscillator subcircuits performancesuch as resonator, feedback, and output matching network. Two techniques areemployed for the analysis purposes. The first method involves the open-loop gain andphase response versus frequency, the second method considers the oscillator as one-portwith negative resistance. Fixed frequency oscillator at 7GHz is realized and tested.
