METHOD AND CONTROL CIRCUIT FOR THE USE OF A POWER AMPLIFIER IN HBT TECHNOLOGY IN A TRANSMITTER IN ZERO INTERMEDIATE FREQUENCY ARCHITECTURE

摘要

The present invention relates to a method for controlling the power emitted by a power amplifier (1) with heterojunction bipolar transistors receiving an input power (Pin) and emitting an amplified output power (Pout) in an architecture. at zero intermediate frequency, comprising a step of detecting the output power (Pout) and adjusting the control voltage (Vc) of the power amplifier (1) by a control loop, characterized in that it provides for a step of adjusting the input power level (Pin) of the power amplifier (1). /P
