Abstract
Mode locked surface acoustic wave oscillators, configured as comb spectrum generators, are stabilized by means of a variable phase in the closed, oscillation loop, the phase being controlled in response to deviations of the low, pulse repetition frequency from a design reference PRF. The variable phase may be provided by a variable phase device inserted in the oscillatory loop, such as varactor-tuned lumped element delay lines or 90.degree. hybrids, or other devices. Or, the variable phase may be provided by a voltage tunable surface acoustic wave device used as the basic oscillator SAW delay line.
