摘要：
A SAW stabilized oscillator (10) includes a phase locking circuit (38,16,20,22,36) 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 (14). A mixer (54) is disposed in the phase locking circuitry and is used as a sub-harmonic phase detector by mixing the fundamental (54a) with an odd harmonic (54b) of the reference signal (10a). The mixer output (54c) is filtered (70) and amplified (72,74) before being supplied to the control voltage input terminal (36′) of a voltage controlled variable phase shifter (36) in the SAW oscillator (14) loop (13).
