A harmonic mixer, comprising:
- a multi-phase LO signal generator, each phase of the multi-phase LO signal generator outputting an LO signal on a signal line;
- a plurality of mixers, each mixer of the plurality of mixers connected to a signal line, the mixer driven by an intermediate frequency (IF);
- and an output network coupled to the outputs of the plurality of mixers,
- wherein the harmonic mixer is configured to perform single-sideband (SSB) up-conversion using in-phase and quadrature (I/Q) local oscillator (LO) signals and corresponding I/Q baseband signals.
