Abstract: A two channel mixer circuit includes a first channel (110) for mixing signals within a first selected band of frequencies at the input (100) thereof with a signal of predetermined frequency to generate signals within a second selected band of frequencies and intermodulation products, A second channel (140, 150) is coupled to the input (100) of the first channel (110) to mix a portion of the provided signals within the first selected band of frequencies with the signal of predetermined frequency to generate signals within the second selected band of frequencies and intermodulation products. A combining circuit (160) is coupled to the first (110) and second channel (140, 150) to combine signals respectively generated thereby in a manner to substantially cancel the intermodulation products and provide output to remaining signals.
