Abstract
This paper presents a 314-344 GHz high output power push-push frequency doubler for radar applications with 1 dBm Psat at 324 GHz and 30 GHz Psat 3 dB–bandwidth. It is driven by a three-stage, cascode-based D-band driving stage, providing a differential saturated output power of 14.3 dBm at 154 GHz with a peak PAE of 4.5% and 13.4 dBm output referred P1 dB. The chip is fabricated using a 130 nm SiGe BiCMOS technology with ft/fmax of 250 GHz / 370 GHz. Thanks to the use of harmonic reflectors an overall peak conversion gain of 20 dB is achieved and remains above 6 dB at saturation.
