3.0 MILLIMETER WAVELENGTH DUPLEXER

Abstract

Effort was concentrated on establishing an initial tube design, scaling experiments at X-band, the assembly of a low level test bench, and the establishment of a precision machine shop. A preliminary tube was designed, and a complete set of drawings were made. Several parts of the tube not contingent upon the electrical parameters of the tube are being made. Low level matching studies have begun with parts scaled to X-band. Initial data show that the required frequency band can be covered with a three-element, band-pass structure having loaded element Q's of approximately six. Many of the parts required for matching studies at 3 mm were made. The necessary microwave components were received, and a 3-mm low level test bench was assembled. A small machine shop consisting of jewelers lathe, drill press, and milling machine, which are capable of the high accuracy work required, was assembled. (Author)
