Abstract:
An integrated superheterodyne dual-conversion tuner upconverts a signal so as to place it outside a reception band, and then downconverts the signal with a non-zero intermediate frequency. A first filter of the bulk acoustic wave type is positioned between the up and down conversion and is calibrated in such a way as to accurately determine its central frequency. A second filter of a microelectromechanical type receives the downconverted signal and is calibrated in such a way as to accurately determine its central frequency.
