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.

Claim (Index 5):
A receiving circuit configured to receive a radio frequency (RF) signal including a data signal and an interference signal and amplifying the RF signal according to an analog gain, the receiving circuit comprising:\n a low noise amplifier (LNA) configured to amplify the RF signal using a first gain to generate an amplified RF signal; an RF power detection circuit coupled to an output of the LNA and configured to detect 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; a mixer coupled to the LNA and configured to generate a second gain according to a bias signal, down-convert the amplified RF signal to a down-converted radio frequency (RF) signal according to a reference clock, and amplify the amplified RF signal or the down-converted RF signal using the second gain; a mixer bias circuit coupled to the mixer and the RF power detection circuit and configured to provide the bias signal to the mixer according to the control signal; and a filter circuit coupled to the mixer and configured to filter out the interference signal from the down-converted RF signal and output the data signal; wherein the analog gain is substantially proportional to the product of the first gain and the second gain.
