Abstract :
Several planar periodic power combining oscillators containing two to six Gunn diodes operating in the X-band region are discussed. The maximum power combining efficiency, 126.7% was obtained from the three-diode oscillator. The frequency dependence of all the power combiners on the bias voltage variation seemed to be independent of the number of diodes. Injection locking was maintained over a large variation of the bias voltage
