摘要:
A receiver front end includes a plurality of in-phase and quadrature phase receive processing blocks operable at first and second frequency bands and further includes a plurality of filtering and amplification blocks disposed within a corresponding ingoing signal path, a plurality of received signal strength indicator (RSSI) blocks coupled to receive an ingoing analog signal from a corresponding plurality of nodes disposed throughout the ingoing signal path, each of the plurality of RSSI blocks producing a signal strength indication, and wherein a baseband processor is operable to receive a selected signal strength indication and to produce at least one gain setting to at least one amplification block within the in-phase or quadrature phase receive processing blocks. In operation, the baseband processor receives a signal strength indication from each RSSI block to determine a total amount of gain and appropriate gain distribution within the receive signal path.
