Abstract

A tuner (9) for a digital satellite television receiver comprises a single conversion stage which produces an IF signal at a low enough frequency to permit a SAW filter (913) to be used to perform symbol shaping as well as the normal IF filtering function. The local oscillator (911) is controlled by a phase locked loop tuning control IC normally used to control the local oscillator (911) of a tuner of a conventional broadcast or cable television receiver. In an exemplary embodiment for tuning RF signals provided by a block converter (3) in the 950 to 1450 MHz frequency range, the IF has a center frequency of 140 MHz.
