Abstract
A comparison is made in a number of scenarios of a current channel gain setting for a receiver to a threshold. If the current channel gain setting is less than the threshold, then current within at least a portion of the receiver is decreased. In one scenario, the comparison is only made in event that no single tone interferer is detected. In another scenario, the comparison is made to a tolerable single tone blocker threshold, and if greater then current is decreased. In another scenario, the comparison is made to an acceptable intermodulation response rejection threshold, and if greater then current is decreased. In yet another scenario, the comparison is made to an acceptable spurious free dynamic range threshold, and if greater then current is decreased. The portions of the receiver for which current decreases are implemented include a low noise amplifier, mixer, voltage controlled oscillator and variable gain amplifiers.
