Patent ID: 7242915

Claim:
A Radio Frequency unit comprising: transmit circuitry that receives Intermediate Frequency (IF) transmit data from a host device, that converts the IF transmit data to an RF transmit signal and that transmit the RF transmit signal; receive circuitry comprising: a Low Noise Amplifier (LNA) operably coupled to receive an RF receive signal; a mixer coupled to receive an output of the LNA; a Band Pass Filter (BPF) coupled to an output of the mixer; a first received signal strength indicator coupled to the output of the mixer that indicates a wideband received signal strength (RSSI_A); a second received signal strength indicator coupled after the BPF that indicates a narrowband received signal strength (RSSI_B); and a LNA gain adjustment block that operates to: determine a LNA gain setting during a guard period immediately following an intended time slot of a prior data frame; determine a LNA gain setting during a guard period immediately preceding an intended time slot of a current data frame; and set the gain of the LNA for the intended time slot of the current data frame to the lesser of the LNA gain setting determined during the guard period immediately following the intended time slot of the prior data frame and the LNA gain setting determined during the guard period preceding the corresponding time slot of the current data frame.
