Single-Chip 135-160 GHz Doubler with more than 150 mW Output Power based on Discrete Schottky Diodes

Abstract

Single chip doubler based on novel diamond-based discrete Schottky diodes is presented here. CVD Diamond technology has been integrated by ACST GmbH in the discrete diode structure to implement in high power multipliers development. A single chip 135-160 GHz doubler able to handle up to 400 mW input power and provide more than 150 mW output power is reported. Conversion efficiency higher than 30 % is performed in band and up to 40% at some frequencies point.
