In a case where two constant envelope signals corresponding to an input signal are generated through analog signal processing, variation in detection sensitivities of amplitudes of those signals is suppressed. At least one of a mixer (24) for detecting an amplitude of a first intermediate signal S1 and a mixer (26) for detecting an amplitude of a second intermediate signal S2 detects an amplitude of a given reference signal, and sampling hold circuits (36, 38) hold a voltage related to those amplitudes. Then, detection sensitivities of the mixer (24, 26) are corrected based on the held voltage. |
