摘要： A power amplification apparatus includes, between a first amplification element for amplifying an input signal and a first output terminal, a second amplification element for further amplifying the input signal amplified in the first amplification element to output to the first output terminal, and a first switch element for controlling the second amplification element to be stop condition. Further, between the first amplification element and a second output terminal, a second switch circuit for controlling the supply of an output from the first amplification element to the second output terminal is provided. When outputting a medium power, the operation efficiency of the power amplification apparatus is improved by reducing a power consumption. Thereby, a total operation efficiency of the power amplification apparatus which outputs either the input signal amplified to a large power or the input signal amplified to a medium power by switching is improved.

摘要： A distortion compensating device which can significantly remove residual distortion, in which a value of matching circuit 11 is set up so that the distortion generated at a gain controlling unit 9 offsets the distortion remaining in a power amplifier 12. That is, the value of the matching circuit 11 is set up so that the phase of the residual distortion included in the output of the matching circuit 11 is rendered opposite to the phase of the residual distortion included in the output of the power amplifier 12. Thus, the residual distortion included in the output of the power amplifier 12 is offset by the residual distortion included in the output of the gain controlling unit 9, thereby the residual distortion can be removed.

摘要： A communication apparatus is small in power consumption and suitable for use in a portable radio communication apparatus. The communication apparatus includes a semiconductor power amplifier integrated circuit which uses a GaAs junction type FET having a gate bias terminal to which a gate bias voltage is applied. The integrated circuit decreases its amount of power consumption in a manner that the integrated circuit is operated to perform an amplification operation during a communication operation and not operated when a communication is interrupted or a time slot is not allotted to the communication apparatus itself. A detector detects a portion of a high-frequency signal to the amplifier circuit to provide an input to a gate bias generator which provides an input to an adder circuit, the output of which controls the bias on the power amplifier.
