ABSTRACT:
A tuner (200) includes a direct digital frequency synthesizer (206) and a mixer (220). The direct digital frequency synthesizer (206) has an output terminal for providing a digital local oscillator signal having a frequency chosen to mix a desired channel to baseband. The mixer (220) has a first input terminal for receiving a tuned radio frequency signal, a second input terminal coupled to the output terminal of the direct digital frequency synthesizer (206), and an output terminal for providing an in-phase baseband signal.
