Title: Gain control amplifier
Inventor: SHICHIRO ISAMU
IPC: H03G1/00
Filed: 1982-03-09
Abstract: PURPOSE:To decrease distortion due to cross modulation caused by the deterioration of linearity of an intermediate frequency amplifying circuit at the start of gain control, by using plural sets of gain control diodes and connecting one side of each diode via a resistor to another side. CONSTITUTION:When a voltage applied to a gain control voltage impressing terminal 14 is sufficiently low and diodes 9, 10, 21 and 22 are not conducted, an emitter current of a TR1 is shared to resistors 12, 16, 17, and 19, and the gain depends on the resistors. When the impressed voltage at the terminal 14 is increased in this state, the diode 21 is conductive first. When the voltage at the terminal 14 is increased further, the diode 9 starts conducting with a delay by the voltage drop across the resistor 19, and the gain control due to the impedance change in the diode 9 is added. This applies also to a TR2. Thus, at the start of gain control, the deterioration of linearity around the leading of diodes is suppressed by the resistor 19.
