Abstract
A double super tuner for receiving television signals from conventional broadcast, CATV, satellite broadcast, and HDTV. A first frequency converter converts an input high-frequency signal in a first intermediate frequency band signal based on a first local oscillator signal. The output of the first frequency converter is band-pass filtered by a dielectric filter. A second frequency converter converts the output of the dielectric filter into a second intermediate frequency band signal based on a second local oscillator signal.
