SiP Tuner With Integrated LC Tracking Filter for Both Cable and Terrestrial TV Reception

摘要

A silicon tuner has been designed for the reception of analog or digital TV signals from a cable or a terrestrial network. It exhibits 5 dB NF over the 42–870 MHz frequency range and integrates a self-calibrated LC tracking filter. This allows 55 dB video SNR under fully loaded spectrum conditions. The $(N+1)$ image channel is rejected by more than 62 dB thanks to a fully integrated full complex mixer with auto calibration. The 5.7 ${hbox {mm}}^{2}$ active die is fabricated in 40-GHz $f _{T}$ BiCMOS 0.25 $mu{hbox {m}}$ technology and dissipates 780 mW running from a 3.3 V supply.
