Patent ID: 7796714

Claim:
A receiver for use in a software defined radio (SDR) multichannel receiver configured to receive signals from multiple transmitters, the receiver comprising: a first channel circuit of N channel circuits, comprising: a band pass (BP) filter that isolates a first frequency bandwidth carrying a signal originating from a first transmitter; and a gain control (GC) feedback circuit configured to adjust a signal provided by the BP filter with respect to a reference voltage; and a second channel circuit of the N channel circuits comprising a second GC feedback circuit configured to adjust a signal provided by a second BP filter with respect to the reference voltage, wherein the second BP filter isolates a second frequency bandwidth different from the first frequency bandwidth carrying a second signal originating from a second transmitter; an N-way splitter coupled to the BP filter and the second BP filter, the N-way splitter providing an input signal to both of the BP filter and the second BP filter; and a multiplexer connected to the GC feedback circuit and the second GC feedback circuit, the multiplexer combining an output from each of the GC feedback circuit and the second GC feedback circuit to provide an output signal.
