Abstract:
1. A tuner comprising a local oscillator for providing a local oscillator signal having a frequency selected from a plurality of local oscillator frequencies and a continuous-time mixer for mixing an incoming signal with the local oscillator signal so as to translate a lower high frequency spectrum of interest and an upper high frequency spectrum of interest to within a passband, improved wherein the local oscillator frequencies of the plurality are spaced such that there is substantially no redundant spectral coverage between: an upper and lower high frequency spectrum of interest translated to the passband with a local oscillator signal having any first local oscillator frequency of the plurality; and an upper and lower high frequency spectrum of interest translated to the passband with a local oscillator signal having any local oscillator frequency of the plurality other than the first local oscillator frequency of the plurality, wherein the passband comprises a range of frequencies passed by a low pass filter and excluding DC.
