Patent ID: 7397868

Claim:
A transceiver, comprising: a transceiver port comprising an antenna for receiving and transmitting high data rate communication signals at radio frequency; circuitry for adjusting a local oscillation frequency based upon a frequency of a received radio frequency (RF) signal received through the antenna; down conversion circuitry coupled to receive the adjusted local oscillation frequency from the circuitry for adjusting and further coupled to receive communication signals at radio frequency from the antenna wherein the down conversion circuitry is operable to produce base band frequency communication signals based upon the adjusted local oscillation and the received communication signals at radio frequency; first received signal strength indication circuit for measuring power levels of signal and interference from a node disposed down stream of the down conversion circuitry and up-stream of low pass filtering circuitry; second received signal strength indication circuit for measuring signal power levels from a node disposed down-stream of the low pass filtering circuitry; and a low noise amplifier operably disposed upstream of the first received signal strength indication circuitry and variable gain amplification circuitry operably disposed down-stream of the low pass filtering circuitry, wherein the transceiver reciprocally adjusts the low noise amplifier and the variable gain amplification circuitry amplification levels based upon outputs of the first and second received signal strength indication circuits.
