SUBMILLIMETER-WAVE COMPONENT DEVELOPMENT
Abstract
Techniques for the design, construction, and evaluation of a 10-db directional coupler, a 0 to 40 db variable attenuator, a 90-degree phase shifter, and a duplexer to operate in the 300 to 1000 gc region were investigated theoretically and experimentally. Quasi-optical, oversize, trough, and Goubau-beam waveguide were studied. Quasi-optical techniques used in oversize wave guide were found to be most suitable and were used in constructing the components. These com ponents were evaluated at 0.9-mm wavelength. The experimental data showed good agreement with the design theorhus, submillimeter compo nents using quasi-optical techniques in over size waveguide can be successfully designed annd fabricated. Some components had higher inser tion loss than desired due to the dielectric dissipation effects. These losses are reduced by using a multiple-dielectric-slab coupling structure.
