ABSTRACT:
A conversion mixer includes a mixing circuit, a duplicating circuit and a loading circuit. The mixing circuit receives a couple of first input signals and a couple of second input signals and mixes the couple of first input signals with the couple of second input signals to output a couple of mixed signals. The duplicating circuit coupled to the mixing circuit receives the couple of mixed signals and duplicates the couple of mixed signals to output a couple of duplicated signals. The loading circuit coupled to the duplicating circuit receives the couple of duplicated signals and outputs a couple of output signals according to the couple of duplicated signals.
