Abstract:
A power amplifier circuit includes an amplifier element that amplifies a signal input to a base and outputs an amplified signal from a collector, and a variable capacitor provided between the base and the collector of the amplifier element. A power-supply voltage that varies in accordance with an envelope of amplitude of a radio-frequency signal is applied to the collector of the amplifier element, and capacitance of the variable capacitor decreases in response to an increase in the power-supply voltage input to the collector of the amplifier element

Claim (Index 1):
A power amplifier circuit comprising:\n an amplifier configured to amplify a radio-frequency signal input to a base of the amplifier and to output an amplified radio-frequency signal from a collector of the amplifier; and a variable capacitor connected between the base of the amplifier and the collector of the amplifier, wherein a power-supply voltage that varies in accordance with an envelope of an amplitude of the radio-frequency signal is supplied to the collector of the amplifier, and wherein a capacitance value of the variable capacitor decreases as the power-supply voltage increases.
