ABSTRACT:
A mixer circuit, and an associated method, mixes together differential input signals with differential mixing signals to form differential output signals. The differential output signals are substantially linearly related to the input signals over an entire range of input signal values. The mixer circuit forms, in exemplary implementations, portions of a radio receiver device or a radio transmitter device, such as the radio receiver and transmitter portions of a cellular radio telephone.
