FIELD: electricity.
SUBSTANCE: SPS receiver may be operated in one of a set of modes to be connected with various bias current devices for the SPS receiver. One of the modes may be selected by an output power level of a transmitter jointly arranged with the SPS receiver. The bias current of a low-noise amplifier (LNA), a mixer and/or an LO generator in the SPS receiver may be specified by the selected mode. In one structure, the first (e.g., low-power) mode may be selected for the SPS receiver, if the output power level of the transmitter is below a switching point. The second (e.g., high-linearity) mode may be selected, if the output power level of the transmitter is above the switching point. The second mode is connected with greater bias current for the SPS receiver, than the first mode.
EFFECT: improved functional characteristics and low power consumption.
