摘要： This invention discloses a power divider, a radio frequency transceiver and a multi-stage power divider, the power divider comprises a variable gain amplifier, a power dividing circuit, a power detection circuit and a comparison circuit. The variable gain amplifier comprises a first input terminal, a control terminal and a first output terminal, the first input terminal is configured to receive a first local oscillation signal, and the first output terminal outputs a variable output signal to the power dividing circuit. The power dividing circuit outputs a second local oscillation signal to a next stage power divider and outputs a third local oscillation signal to an up/down converter. The power detection circuit outputs a detection voltage. The comparison circuit receives a reference voltage and the detection voltage and compares the reference voltage with the detection voltage and outputs a bias voltage to the power terminal based on a comparison result.
