  • Publication number: 20050195335
    Abstract: A front end circuit for a television receiver includes a demultiplexer for inputting a multi-band signal from a signal source and separating the multi-band signal into corresponding bands. A plurality of amplifiers adjust gain on signals corresponding to the bands. A multiplexer combines outputs of the amplifiers into a gain-adjusted signal. A plurality of switches direct selected bands to corresponding tuners. The amplifiers are low noise amplifiers. The amplifiers adjust gain between the bands so as to have similar signal strength in the bands. A cable TV input may also be used, wherein the switches also direct signals from the cable TV to the corresponding tuners. Each amplifier can output two (or more) identical signals for its corresponding band, the multiplexer can be a dual multiplexer, and an output of the multiplexer includes only bands selected for direction to the tuners.
