Abstract

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