Abstract
A method of receiving an RF signal is applied to a receiving circuit of a wireless communication system and amplifies the RF signals according to an analog gain. The RF signal includes data signals and interference signals. The method includes steps of: employing a low noise amplifier (LNA) to amplify the RF signal according to a first gain to generate an amplified RF signal, the first gain being associated with a first bias signal; detecting the amplified RF signal in an RF band to generate a control signal corresponding to the power of the amplified RF signal, the control signal being an analog signal; providing the first bias signal to the LNA according to the control signal; down-converting the amplified RF signal to generate an intermediate frequency or baseband signal; and filtering the intermediate frequency or baseband signal to filter out the interference signal and thus obtain the data signal.
