A multi-standard integrated television receiver is disclosed. According to the invention, a RF tracking filter is provided to receive a RF signal and then filter out a fifth order and above harmonics and a band-pass filter is provided to further eliminate harmonics. Moreover, a double quadrature mixer is provided to remove third order harmonics. Accordingly, the quality factor requirement of the RF tracking filter and the linearity requirement of the band-pass filter are relaxed. Thus, the RF tracking filter and the band-pass filter can be fully integrated without any external components. |
