Patent ID: 7406304

Claim:
An electronic component, comprising: an integrated circuit embodied on a monolithic substrate and comprising: a superheterodyne type tuning module with non zero intermediate frequency dual upconversion then downconversion, possessing an input able to receive digital terrestrial or cable television analog signals composed of several channels, a bulk acoustic wave type bandpass filter disposed between two frequency transposition stages of the tuning module and delivering a filtered analog signal containing the information conveyed by a desired channel and adjacent channels information, wherein the bulk acoustic wave type bandpass filter has a first passband having a bandwidth wider than a plurality of channels, a microelectromechanical type bandpass filter disposed downstream of a second frequency transposition stage and able to eliminate the adjacent channels information, wherein the microelectromechanical type bandpass filter has a second passband having a bandwidth in excess of a single channel; first means for determining a center frequency of the first passband for the bulk acoustic wave filter, and second means for determining a center frequency of the second passband for the microelectromechanical filter.
