    摘要： In a high frequency power amplifier circuit in which bias voltages are applied to the transistors for amplification by current mirroring, this invention enables preventing waveform distortion near the peak output power level by allowing sufficient idle currents to flow through the transistors for amplification, while enhancing the power efficiency in a low output power region. The power amplifier includes a detection circuit comprising a transistor for detection which receives the AC component of an input signal to the last-stage transistor for amplification at its control terminal, a current mirror circuit which mirrors current flowing through that transistor, and a current-voltage conversion means which converts current flowing in the slave side of the current mirror circuit into a voltage. In the detection circuit, a voltage from a bias circuit for generating the bias voltages for the transistors for amplification is applied to the control terminal of the transistor for detection and output of the detection circuit is applied to the control terminal of the last-stage transistor for amplification.

    摘要： Switching characteristics in an SPDT switch are improved to reduce the rise delay in a low power slot following after a high power slot. Control terminals of an SPDT switch are respectively provided with backflow prevention circuits. The backflow prevention circuit is configured to have two transistors and a diode. In a transmission mode, for example, when a time slot where a high power passes through transistors is followed by a time slot where a low power passes through, the electric charges accumulated in the gates of the transistors are blocked. In the case where the transistors are in the OFF state, the electric charges accumulated in the gates of the transistors are immediately discharged to allow the transistors to be completely turned OFF.
