A waveguide embedded 250 GHz quasi-optical frequency-tripler array

Abstract

A waveguide embedded 250 GHz HBV-varactor quasi-optical multiplier array is presented. The module utilizes a mechanically compact and simple shim system, combining the large array power handling capability with the convenience of waveguide interfaced circuits. At the same time this approach offers excellent power and frequency scalability. The current tripler prototype produces a non saturated output power of 8 mW at 248 GHz during initial measurements at medium pump power.

A Tunable 240–290 GHz Waveguide Enclosed 2-D Grid HBV Frequency Tripler

“…The frequency multiplier module presented in Fig. 1 builds upon the work in [17] with the addition of an improved matching network in the form of an input matching tuner. The input tuner uses a movable dielectric slab in the input waveguide to optimize the input matching.…”
