A vector signal processor (80) can include a digital to time converter (DTC), an RF memory (RFM) or an electronically tunable transmission line (ETTL) (82), a mixer, or other phase shifter (70) for receiving an output of the DTC or the ETTL, and a controller for selectively controlling the harmonic processing of the DTC, RFM or the ETTL and the phase processing of the mixer. The vector signal processor can uncouple a relative phase of a fundamental signal with respect to harmonics of the fundamental signal. The vector signal processor uses selective phase processing of the fundamental signal and related harmonic components. In a specific embodiment, the vector signal processor cancels harmonics of the fundamental signal and more specifically can cancel a third harmonic of the fundamental signal.
