Abstract
Embodiments of the disclosure relate to reducing power consumption in a remote unit of a wireless distribution system (WDS) for intermodulation product suppression. Intermodulation products generated by a power amplifier circuit can leak from a downlink signal path into an uplink signal path to degrade sensitivity of the uplink signal path in a remote unit. In this regard, the remote unit is configured to measure a power of the leaked intermodulation products and enables a selected number of power amplifiers in the power amplifier circuit for reducing the measured power of the leaked intermodulation products to a predetermined threshold. By enabling only the selected number of power amplifiers based on the measured power of the leaked intermodulation products, it is possible to avoid enabling an excessive number of power amplifiers in the power amplifier circuit, thus helping to reduce power consumption for intermodulation product suppression.
