Abstract
A microwave oscillator capable of being switched into or out of the oscillating state within a fraction of the period of oscillation. The instant-on microwave oscillator permits both the generation and modulation of a microwave signal by using a single active microwave semiconductor device which is a resonant tunneling diode. The instant-on microwave oscillator circuit includes a conductive transmission line having an impedance Z.sub.O with a corresponding ground plane; and a pair of output terminals connected one on each of the transmission line and the ground plane. An impedance Z.sub.L, having an impedance value which is less than ZO, is positioned across the output terminals. A pair of input terminals is connected at the opposite end of the transmission line, one on each of the transmission line and the ground plane with a resonant tunneling diode connected across the input terminals. An impedance Z is connected to the input terminal on the biased side of the transmission line. Means are provided for applying a square wave shaped switched power supply signal to the resonant tunneling diode through impedance Z. Means are also provided for separating the square wave and oscillati…
