MULTI-BAND BROADCAST TUNER

摘要

A system for receiving radio- frequency signals includes a first input path, a second input path, a selector, and a mixer. The first input path is capable of transmitting to the mixer a first input signal propagating in a first portion of the radio- frequency spectrum, while the second input path is capable of transmitting to the mixer a second input signal propagating in a second portion of the radio- frequency spectrum. The selector is capable of selectively coupling one of the first input path and the second input path to the mixer. Additionally, the mixer is capable of receiving an input signal and downconverting at least a portion of the input signal that is propagating within a selected frequency range. The mixer is also capable of outputting the downconverted portion of the input signal.
