    摘要： A high-frequency power amplifier comprises a transistor for high-frequency power which operates and whose current-voltage characteristics greatly change when positive voltage is supplied on its input terminal, an input bias circuit, an output bias circuit, an input impedance matching circuit, an output impedance matching circuit, and a positive voltage generation circuit. The positive voltage generation circuit comprises a detection circuit which detects part of the high-frequency power which is entered to or outputted from the transistor for high-frequency power, a rectification circuit which rectifies the part of the high-frequency power outputted from the detection circuit and outputs pulsating positive voltage, and a smoothing circuit which smoothes the pulsating positive voltage outputted from the rectification circuit and outputs positive voltage. The positive voltage generation circuit outputs positive voltage which increases or decreases in accordance with an increase or decrease in the detected part of the high-frequency power to the input terminal of the input bias circuit, without intervention of a direct-current power supply.

    摘要： When a signal of a double frequency is generated from the original signal, conventionally a 90-degree phase-shift circuit is necessary to suppress an output of a DC component and efficiently obtain a double wave. According to the present invention, an equal RF signal is inputted to input terminals and an output is matched with a frequency as high as that of the original frequency in a Gillbert cell double-balanced mixer, so that a doubled output is obtained with no DC offset. According to the circuit configuration of the present invention, it is possible to provide a circuit readily performing integration and to efficiently output only a double frequency merely by inputting a simple differential signal without the need for the original signal which has been phase controlled. Further, a DC short circuit in the resonance circuit makes it possible to eliminate a DC offset voltage in an output.
