Abstract

This paper describes a 0.34THz Schottky varactor frequency doubler with 50% PAE. We focus on the design of frequency doubler input matching, using the single side heightening waveguide to reduce reflection and expand bandwidth The simulation results show that when the input power is 100 mW, the frequency doubler efficiency is more than 40% from 0.33 THz to 0.36 THz, the output power is more than 40 mW and the maximum efficiency is up to 50%.

Abstract

This paper proposes two terahertz monolithic integrated doublers in the terahertz band (170 GHz, 340GHz), have been designed and fabricated on a 15μm thick GaAs film substrate. The front stage frequency multiplier adopts eight anodes and the rear stage adopts six anodes. Measurement has shown that the efficiency is greater than 20% in the frequency range of 157-177GHz (First stage) with the input power of 300mW, and the peak efficiency at 170GHz is 26.25%. The simulation showed efficiency is greater than 40% in the frequency range of 330-350GHz(Second stage) with the input power of 60mW, and the peak efficiency at 341GHz is 46%.
