摘要： PROBLEM TO BE SOLVED: To lower a bias voltage for controlling the bias of a power amplifier using HBTs, etc., and improve ACPR. SOLUTION: The power amplifier module 5 usable for portable telephones, etc., has a bias control circuit 7, which converts a bias voltage Vconst into a current through MOS transistors T1, T2, thereby reducing a voltage drop to lower the value of the bias voltage Vconst. A bias control circuit 7 outputs a bias control signal BC to a high-frequency amplifier 6 via low-pass filters 17, 18. The low-pass filters (17, 18) are composed of an inductance (Lp1, Lp2) and a capacitor (Cp1, Cp2). The capacitors Cp1, Cp2 attenuate an envelope frequency and the inductances Lp1, Lp2 check the impedance change at a carrier frequency of a modulated signal. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To avoid increase in power gain due to a self-bias phenomenon that is generated in amplification by using an HBT or the like, and to efficiently carry out high-frequency amplification.
SOLUTION: In a power amplification module using a multifinger transistor, a self-bias suppression circuit BC is provided at the high-frequency power amplifying section. The self-bias suppression circuit BC is composed, by connecting N resistors Rc1 to RcX in parallel and is connected to resistor Rb1 to RbN, that are base resistors in common. In the amplification of a high-frequency signal, the resistors Rc1 to RcX enable the restraint of the self-bias phenomenon, where a base current increases as the power of an output signal RFout increases. As a result, a high-linearity amplifier can be achieved.

摘要： A high frequency power amplifying apparatus is provided with an amplifying section with a plurality of amplifying stages connected in cascade. A power control signal is supplied to the amplifying section through a control terminal so as to control the output of the high frequency power amplifying apparatus. Each of the amplifying stages has a gain smaller than that of a preceding stage. Gain control signals generated from the power control signal are supplied to the respective amplifying stages. Dividing resistors are connected in series with one another between the control terminal and a reference potential so as to divide the voltage of the power control signal to thereby generate a plurality of different gain control signals. Different ones of the gain control signals are supplied to the respective amplifying stages, an absolute value of a voltage of the gain control signal applied to each stage is smaller than that applied to an earlier preceding stage.
