Abstract :
A technique for the optimal computer-aided design of MMIC oscillators is described. A novel dual-source technique is used in conjunction with computer simulation in order to obtain the terminating impedances required by the FET to ensure the optimal circuit conditions needed to obtain the required frequency and power output from the oscillator. A number of GaAs MESFET MMIC oscillators have been designed and fabricated. Experimental measurement results agree very closely with the predicted data for the complete set of working circuits
