摘要： A detector circuit for detecting degradation in the distortion characteristics of a power amplifier based on signals from both ends of a coupled line of a directional coupler. The detector circuit includes a phase shifter/attenuator for phase shifting and attenuating a signal from a coupled terminal of the coupled line, a differential amplifier for outputting difference between an output signal from the phase shifter/attenuator and a signal from the isolated terminal of the coupled line, a wave detector circuit for converting the difference into a DC signal, and a comparing circuit for determining whether the voltage level of the DC signal exceeds a predetermined level. When degradation in the distortion characteristics of the power amplifier arises, the phase shifter/attenuator phase shifts the signal from the coupled terminal and outputs a signal 180° out of phase with the signal from the isolated terminal.

摘要： A power amplifier and bias circuit includes a combination circuit in which a voltage drive bias circuit and a current drive bias circuit are connected in a parallel relationship with each other. The power amplifier bias circuit also includes an idle current control circuit which uses the collector voltage of amplifier transistors. When the collector voltage of the amplifier transistors is lower than the threshold voltage of a first transistor (approximately 1.3 V), the first transistor is turned off. At that time, since the reference voltage (2.4-2.5 V) is higher than the voltage for turning on both a second transistor and a diode (namely, approximately 1.3 V plus 0.7 V), a current flows and the first transistor turns on. As a result, a current is drawn from the bases of the amplifier transistors to GND through two resistances, so that the idle currents of the amplifier transistors decrease.

摘要： An amplifying transistor for amplifying a radio frequency signal between an input terminal and an output terminal. The cathode of a first diode is connected to the input terminal and the anode of a second diode is connected to the output terminal. A matching and attenuating circuit is connected between the anode of the first diode and the cathode of the second diode. A matching and attenuating circuit reduces impedance mismatches on the input terminal side and the output terminal side, and attenuates the radio frequency signal. In an amplification mode, a bias circuit supplies a bias current to an amplifying transistor and a current mirror circuit turns off the first and second diodes. In an attenuation mode, the bias circuit supplies no bias current to the amplifying transistor and the current mirror circuit turns on the first and second diodes.
