Claim Text:
1. A method of controlling power dissipation in a receiver signal path of a receiver comprising: a) receiving an input signal by the receiver; b) providing a first signal indicative of the sum of a desired signal and interfering signals in the input signal at a first location in the receiver signal path; c) providing a second signal indicative of the sum of a desired signal and interfering signals at a second location in the receiver signal path, the relative proportions of the desired signal and the interfering signals in the second signal being different from the relative proportions of the desired signal and the interfering signals in the first signal; d) deducing a strength of the desired signal relative to the strength of interferer signals in the input signal from a combination of the desired signal and the interfering signals in the first signal relative to a combination of the desired signal and the interfering signals in the second signal; e) scaling an impedance of at least a component in the receiver signal path responsive to the result obtained in d); wherein the scaling of the impedance of the at least a component in the receiver signal path results in lower power dissipation for higher strengths of the desired signal relative to the respective strength of an interferer signals in the input signal than for lower strengths of the desired signal relative to a strength of the respective interferer signals in the input signal.
