ABSTRACT:
A surface acoustic wave oscillator comprises a surface acoustic wave delay line and amplifier. The phase difference between signals received from two transducers on the surface acoustic wave delay line is measured by a phase sensitive detector whose output is used to control a phase correction circuit. The oscillator may oscillate at a steady frequency or be frequency modulated.
