| Popis: |
A frequency tripler has been developed using an integrated planar back-to-back barrier-n-n/sup +/ (bbBNN) varactor device in a waveguide mount at 220 GHz. The multiplier is based on a novel split-waveguide block design and a new fully integrated planar device architecture. Planar GaAs bbBNN devices have been combined with quartz microstrip filters in a wafer level circuit integration process. A flange-to-flange tripling efficiency of 5%, the highest yet reported from a bbBNN structure at this frequency, has been obtained. Details of the device fabrication process, block design and measured performance are presented. > |
