Abstract:
1. A method for processing a radio frequency (RF) signal in a RF receiver, the method comprising: receiving the RF signal at the RF receiver; amplifying the RF signal on a main path in a component with an adjustable level of amplification; measuring at a first power detector a first power value of the RF signal after amplification by the component; detecting that the first power value of the RF signal is larger than a first threshold; conveying the RF signal to a bypass path that produces less amplification than the main path in response to detecting that the first power value of the RF signal is larger than the first threshold; measuring at a second power detector a second power value of the RF signal after amplification by the bypass path; detecting that the second power value of the RF signal is smaller than a second threshold; conveying the RF signal to the main path in response to detecting that the second power value is smaller than the second threshold; measuring at a third power detector a third power value of the RF signal after amplification by the main path or the bypass path; detecting whether the third power value is larger or smaller than a preferred power value for the main path or the bypass path; and decreasing or increasing the amount of amplification on the main path or bypass path in response to detecting that the third power value is larger or smaller than the preferred power value.
