摘要：
A radio frequency front end for a television band receiver and spectrum sensor includes a first plurality of adaptive matching networks connected to a signal summer that combines signals received by the first plurality of antennas respectively connected to the first plurality of adaptive matching networks and outputs a combined signal to each of a second plurality of downconverter/tuners. The downconverter/tuners are respectively or collectively connected to an analog to digital converter that converts output of the second plurality of downconverter/tuners into at least one digital signal that is output to the television band receiver and spectrum sensor.
