Self-pulsed high-efficiency avalanche-diode oscillators

Self-pulsed microwave power outputs have been generated from avalanche diodes operating in the anomalous mode. A delay line has been used in achieving self-pulsed oscillation with rectangular pulse shape. L-band power outputs of 12 W peak at 50 percent duty cycle have been obtained, with 22 percent efficiency. CW oscillation has also been obtained from the same diodes.
