Abstract
Satellite set-top boxes (STB) are increasingly being designed with multiple tuners, making them capable of receiving more than one program at a time. In addition, satellite STBs are increasingly being designed with multiple inputs, to permit reception of additional channels that will not fit within the conventional satellite intermediate frequency (IF) band (950-2150 MHz). Often, the STB must route these multiple inputs to the multiple tuners with some form of switching function, to allow each tuner to receive all channel bands. Accordingly, the invention includes an RFIC with two RF inputs and three RF outputs, and a crossbar switch that can route any input to any output. The two inputs are amplified by low-noise amplifier stages.
