摘要： A phase modulation (PM) noise reducer includes: an amplitude modulation (AM) detector to receive a primary oscillator signal and to produce an AM detector signal, the primary oscillator signal including a first PM noise; and a control circuit to receive the AM detector signal, to produce a control signal, and to communicate the control signal to a phase shifter, wherein the phase shifter receives the primary oscillator signal and control signal, and the oscillator produces a secondary oscillator signal that includes a second PM noise that is less than the first PM noise, and further including; a PM detector and power splitter receives the primary oscillator signal, splits a power of the primary oscillator signal, and communicates the primary oscillator signal to the AM detector and PM detector.
