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.
