ABSTRACT:
An upconverter includes a switching architecture configured to receive an input signal, a first local oscillator (LO) signal, and a second local oscillator (2LO) signal that is at a frequency that is twice a frequency of the local oscillator (LO) signal, wherein the switching architecture is configured to switch the input signal on transitions of the second local oscillator (2LO) signal, and wherein the first local oscillator signal and the second local oscillator signal are combined to form combined LO 2LO switching signals.
