摘要： A high frequency power amplifier is provided that prevents loop oscillation at a low frequency caused by a closed loop formed between combined semiconductor devices. Previously, coupled-line directional couplers or capacitors for low frequency rejection have been used to prevent the closed loop from being formed. Also, a circuit including a resistance component required for attenuating self-oscillation has been provided. Therefore, to prevent both loop oscillation and self oscillation, two circuits have been required. Accordingly, a high frequency power amplifier is provided with a low frequency prevention circuit that attenuates the passing of each frequency of loop oscillation and self oscillation to each signal line divided by a power divider. Thus, the two circuits respectively required for preventing the loop oscillation and self oscillation of a travelling wave combine type amplifier can be formed by one low frequency prevention circuit.

摘要： The envelope tracking power supply includes a plurality of variable voltage supplies. A power supply controller of a power amplifier controls the plurality of variable voltage supplies so as to precisely divide the power supply voltage in a high frequency area, based on the voltage distribution of a received transmitted base band signal, in order to maximize the power added efficiency of the power amplifier. The power supply controller includes a threshold memory including a plurality of first zones, and a frequency memory including a plurality of second zones. The power supply controller changes the threshold held in the first zones so that each second zone approaches the average of the second zones.

Further, in a multistage power amplifier including first and second amplifier circuits each having one or more of bipolar transistors, a bipolar transistor in the first amplifier circuit uses an emitter having a planar shape in a rectangular shape, and a bipolar transistor in the second amplifier circuit uses an emitter having a ring-like shape and a base electrode only on the inner side of the emitter.

摘要： The present invention provides a power amplifier module used in a cellular phone or the like. In the power amplifier module, a bias control circuit converts a bias voltage to a current by MOS transistors, whereby a voltage drop is reduced and the value of the bias voltage is lowered. Bias control signals outputted from the bias control circuit are inputted to a high-frequency amplifying unit through low-pass filters. The low-pass filter comprises an inductance, and a condenser. Each of the condensers attenuates an envelope frequency. Each of the inductances suppresses a change in impedance at a carrier frequency of a modulation signal.

摘要： The present invention provides a radio frequency power amplifier which may not introduce radio frequency loss during switching power amplifier units between high and low output power levels. By connecting a first-stage matching network M12 and first-stage matching network M13 to respective output nodes of a power amplifier unit A11 and power amplifier unit A12 that either one operate by switching, connecting the output nodes of the first-stage matching network M12 and M13 in parallel, connecting a last-stage matching network M11 between the junction of M12 and M13 and the output terminal OUT, the first-stage matching networks M12, M13, and last-stage matching network M11 are formed, for both power amplifier units A11 and A12, so that impedance matching is established between the output terminal OUT and the power amplifier unit in operation when one unit is in operation the other is in stop of operation. The present invention allows switching from one power amplifier unit to the other without the need of a radio frequency switch.
