Abstract: An amplifier circuit is provided for amplifying a radio frequency signal within one frame of a radio frequency signal by using multiple discrete voltages supplied from the tracker circuit. The amplifier circuit includes a power amplifier and an RC series circuit including a resistor and a capacitor that are connected in series between the ground and a voltage supply path between the tracker circuit and the power amplifier.
