ABSTRACT:
A frequency mixer that generates out of phase sum signals and uses the out of phase relationship to absorb sum signal energy in an energy absorbing component. A frequency mixer according to the present teachings includes a set of mixing devices that generate a first sum signal and a second sum signal in response to an input signal and a drive signal such that the first sum signal is out of phase in relation to the second sum signal. A frequency mixer according to the present teachings includes an energy absorbing component that absorbs the out of phase sum terms from the mixing devices.
