Abstract
A radio frequency signal amplification device includes an amplification circuit, an impedance matching circuit, a frequency detection circuit, and a control circuit. The amplification circuit has an input terminal and an output terminal. The amplification circuit amplifies a radio frequency (RF) signal received from the input terminal, and generates an amplified radio frequency signal to the output terminal. The impedance matching circuit is coupled to the input terminal or the output terminal of the amplification circuit. The impedance matching circuit receives the radio frequency signal and provides an impedance matching the radio frequency signal, or receives the amplified radio frequency signal and provides an impedance matching the amplified radio frequency signal. The frequency detection circuit determines a frequency band to which the radio frequency signal belongs. The control circuit adjusts the impedance of the impedance matching circuit according to the frequency band.
