ABSTRACT:
A wideband tuner for television signals in the VHF, CATV and UHF bands comprises a VHF tuning section coupled to a VHF receiving terminal, a CATV tuning section coupled to a CATV receiving terminal and a UHF tuning section. A switch selectively couples the UHF section to the output of the CATV tuning section or signals from a UHF receiving terminal. Each of the CATV and UHF tuning sections includes a differential mode modulator. In the CATV reception mode, the modulator of the CATV section converts the received CATV signal on an upper-side band differential mode to a UHF frequency, while the modulator of the UHF section converts the UHF frequency CATV signal to the standard intermediate frequency in a lower-side band differential mode. In the UHF reception mode, the UHF section modulator converts the UHF signal in an upper-side band differential mode to the standard intermediate frequency, while the CATV section is disabled.
