Abstract
An integrated circuit includes a dual-conversion tuner, firstly upconverting so as to place a signal outside the reception band, then downconverting with zero intermediate frequency. A bulk acoustic wave type filter is calibrated in such a way as to accurately determine its central frequency. This filter is positioned between the two frequency transposition stages of the tuner. After baseband filtering, the signals are digitized then processed in a digital block BNM which includes a channel decoding module.
