Abstract
The invention provides a broadband tuner with a reduced odd harmonic mixing and a method for reducing odd harmonic mixing in the broadband tuner. The broadband tuner includes an arrangement of one or more filters, a plurality of mixers and one or more adders. The plurality of mixers mix a plurality of input Radio Frequency (RF) signals with one or more Local Oscillator (LO) signals, to generate a plurality of mixing products. The LO signals may be square wave LO signals with predefined amplitude coefficients and phases. The plurality of mixing products are then added by the adders to reduce mixing of the odd harmonics of the LO signals.
