    Abstract:

    A high efficiency 285 GHz Schottky diode tripler has been demonstrated based on the face-to-face differential configuration. The proposed concept could improve the power handling capability by a factor of two compared to the traditional balanced circuit based on on-chip capacitors. Meanwhile， the tripler could provide improved DC bias networks with perfect amplitude and phase balance， which shows lower insert losses by leaving out the high required on-chip bypass capacitor. The proposed triple frequency multiplier features inherent suppression on even-order harmonics with the face-to-face differential topology， which ensures better conversion efficiency with doubled anodes. The fabricated tripler has been proved to exhibit a 12% peak efficiency for a nominal driven power of 140~210 mW.
