Abstract
A predetermined delay is provided for a microwave input signal by a delay line having a frequency divider circuit including a negative resistance semiconductor device responsive to the microwave input signal and a D.C. bias voltage. The frequency divider circuit converts the input signal at frequency f.sub.1, to a signal at a frequency, f.sub.2, within the operating range of an acoustic delay device coupled to the frequency divider circuit. A frequency multiplier circuit coupled to the acoustic delay device multiplies the frequency, f.sub.2, of the delayed signal from the acoustic device to the frequency, f.sub.1, of the input signal.
