ABSTRACT:
A SAW stabilized oscillator includes a phase locking circuit which is phase locked to a lower frequency reference signal having an odd order difference with respect to the fundamental frequency of the SAW oscillator. A mixer is disposed in the phase locking circuitry and is used as a sub-harmonic phase detector by mixing the fundamental with an odd harmonic of the reference signal.
