description A high-frequency electric power amplifying device (205A) is provided with a power source device (105A) for a high-frequency electric power amplifying circuit, an RF signal processing circuit (20), and a high-frequency electric power amplifying circuit (100). Bidirectional converters (CONVa-CONVn) capable of charge feeding/regeneration are provided between an input part for an input voltage and an output part for an output voltage. A converter control circuit (9) detects an envelope of an RF input signal, and sets and switches the resonance frequency and amplitude of the bidirectional converters (CONVa-CONVn) so that an output voltage follows a variation in amplitude of an enveloped input signal. A delay time detection circuit (12) ascertains the delay time of the power source device (105A) for the high-frequency electric power amplifying circuit, and performs adjustment through use of a delay adjustment circuit (22).
