Abstract

Circuits systems and methods for frequency translation and signal distribution includes a downconverter circuit having first and second inputs coupled to receive respective first and second input signals, and an output for providing a downconverted output signal. The downconverter circuit includes a mixer circuit, a first switch, and a second switch. The mixer includes a first input coupled to a reference source, a second input, and an output coupled to the downconverter circuit output. The first switch includes a first port coupled to the downconverter circuit first input, and a second port switchably coupled to the mixer circuit second input. The second switch includes a first port coupled to the downconverter circuit second input, and a second port switchably coupled to the mixer circuit second input.
