ABSTRACT:
An microwave analog frequency divider capable of ten percent bandwidth at 10 GHz has push-push amplifiers forming an injection locked oscillator. The input frequency f.sub.i is injected at the amplifier reference terminals. The amplifier control terminals are coupled by L's and the reference terminals are coupled by C's and the reference and control terminals form with the L's and C's a resonant circuit tuned approximately to the output frequency f.sub.o =f.sub.i /N, where N is the divisor. Parallel resonant circuits in the f.sub.i injection path have high impedance at f.sub.o to prevent loading of the oscillator. A control device in the f.sub.i injection path turns the oscillator on when f.sub.i is present and off when f.sub.i is absent. Matching networks are included at input, output and between the control device and the oscillator to obtain efficient operation.
