Design and simulation of microwave oscillator

Abstract EN

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.
