Radio frequency tuner

A radio frequency tuner comprising:

• a plurality of inputs for receiving signals in a plurality of frequency ranges, each signal having a component associated with each of one or more channels within the frequency range, wherein at least two of the frequency ranges at least partially overlap;
• a plurality of upconverters configured to be active one at a time, wherein each of said upconverters, when active, converts a selected signal component associated with a desired channel of the one or more channels to a first intermediate frequency above all of said frequency ranges to generate an intermediate signal;
• a switch to select which of the plurality of upconverters are active by supplying power to an active frequency upconverter;
• a controller to simultaneously control the switch and select a desired channel for reception;
• and
• a downconverter arranged to convert said intermediate signal to a second intermediate frequency below all of said frequency ranges.

A method of radio frequency tuning, comprising:

• receiving signals in a plurality of frequency ranges on a plurality of inputs, each signal having a component associated with each of one or more channels within the frequency range, wherein at least two of the frequency ranges at least partially overlap;
• selecting one of a plurality of first frequency changers to be active, wherein each of said first frequency changers, when active, converts a selected signal component associated with a desired channel of the one or more channels to a first intermediate frequency outside all of said frequency ranges to generate an intermediate signal;
• supplying power to one of the plurality of upconverters to select an active frequency upconverter;
• and
• converting said intermediate signal to a second intermediate frequency outside all of said frequency ranges.
