Title: High frequency amplifier circuit and receiver
Inventor: TOMIYAMA HITOSHI
IPC: H03G1/00
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To realize a high frequency amplifier circuit having a gain control circuit with less current consumption and low distortion that controls gain without the need for using an attenuation circuit or the like. SOLUTION: An amplifier that amplifies a high frequency signal input consists of an input transistor(TR) 32 and an output TR 33 that are connected in cascade. The amplifier is provided with a bias circuit 40 that detects a DC component Ic of collector currents of the TRs 32, 33 and controls a base current Ib of the input TR so as to make the DC component constant. A shunt TR 70 is connected between a base of the input TR 32 and one line of a power supply. A base current of the input TR 32 flows to a resistor connected between the base and the emitter of the shunt TR. Then collector current Ic of the input TR is decreased by decreasing a base voltage of the output TR 33 in response to a gain control signal to reduce the gain of the amplifier and to operate the shunt TR 70 like a shunt.
