SIGNAL GENERATION CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a signal generation circuit that generates a low distortion phase signal and amplitude signal from an input signal.SOLUTION: The signal generation circuit includes a limiter 3 for receiving and saturating to a limit voltage an input signal RFin to generate a phase signal Sp indicating a phase component of the input signal, and a mixer 1 for receiving the input signal RFin and the phase signal Sp to generate an amplitude signal Se indicating an amplitude component of the input signal.
