MILLIMETER AND SUBMILLIMETER COMPONENT DEVELOPMENT.
Abstract
Techniques for design of filters, ferrite devices, diode mounts, and radiation detectors in oversize waveguide are being investigated. Theoretical and experimental results are presented in this report. The 2 and 0.9 mm regions of the dielectric slab filters were evaluated. In addition, the effect of small-waveguide dissipation on the dielectric slab filters was derived. Experiments have continued on Faraday rotation in oversize waveguide. First measurements have been made at 1 mm. An isolator has been constructed. A new type of millimeter/submillimeter mixer using bulk semiconductor was analyzed and successfully demonstrated. The analysis was checked using a low-frequency-prototype consisting of a bolometric mixer operating at 1 Mc. Millimeter mixing was obtained in the 30 to 40 Gc region using bulk n-type indium antimonide as the mixer element. A conversion loss of 24.5 db was measured using nonoptimum material. When corrected for mismatch losses and other effects, a conversion loss of 15.5 db is calculated. (Author)
