Abstract
This article presents a harmonics-recycling (HR) frequency quadrupler that achieves high efficiency, wide band- width, and large output power simultaneously. To improve the efficiency, both the differential-mode (f 0, 3f 0) and common-mode (4f 0) signals are reused by the harmonic recycler. Addition- ally, the amplitude–phase coordinating and mode-staggered-peak techniques are introduced to reject unwanted harmonics and expand the bandwidth. A proof-of-concept HR quadrupler is fabricated using 4
