Abstract
In this paper, the Gain Saturation Approximation method is used for the design of a 4.5 GHz GaAs MESFET Oscillator. This method is based on S-Parameter simulation of the initial oscillator topology including the transistor model. A computer-aided-design was employed for optimizing and simulating the designed circuit to obtain the conditions of oscillation. To verify this work, the optimized circuit is fabricated, by using microstrip technology, and measured. The optimized circuit is also simulated using MDS program. Good agreement between simulation and measurement is obtained.
