Abstract: This letter presents an approach to design the fourth-harmonic mixer based on a pair of antiparallel Schottky diodes. To implement the proposed fourth-harmonic mixer, a two-level local oscillator (LO) low-pass filter is used to suppress… read more here.

Abstract: Fractional-N phase-locked loops using Harmonic-Mixer (HM) based feedback offer good phase noise and spur performance without relying on complex calibration schemes. The HMs in prior art are often realized using the Sample-and-Hold (S/H) operation. This,… read more here.
