brief introduction： A phase modulator is a circuit in which the phase of a carrier wave is controlled by a modulated signal. There are two kinds of phase modulation: direct phase modulation and indirect phase modulation. The principle of direct phase modulation is to use the modulated signal to directly change the parameters of the resonant loop, so that the carrier signal will generate phase shift when passing through the resonant loop and form phase modulation wave. The indirect phase modulation method first modu
