Title: Amplitude modulation circuit
Inventor: SHIMADA NORIHITO
IPC: H03C1/38
Filed: 1988-02-12
Abstract: PURPOSE:To reduce the average power consumption by outputting a carrier in response to a modulation signal in the absence of a modulation signal and increasing the power consumption in response to the modulation signal in the presence of the modulation signal. CONSTITUTION:The impedance between the collector and emitter of control transistors (TRs) 11, 12 is increased in the absence of the modulation signal and the collector voltage of a TR 3 to be modulated is lowered, then a high frequency output is decreased. The impedance between the collector and emitter of the control TRs 11, 12 is decreased in response to the impedance between the collector and emitter of the control TRs 11, 12 in response to the modulation signal, resulting in increasing the collector voltage of the TR 3 to be modulated, the high frequency output is increased and the modulation signal is superimposed onto the collector voltage of the TR 3 to be modulated, then the high frequency output is subject to amplitude modulation. Thus, the power consumption is less in the absence of the modulation signal and the power consumption is increased in response to the level of the modulation signal in the presence of the modulation signal. Thus, the power consumption is reduced.
