Filter Reflection Image Guide Oscillator and Solid State Line Scanning Device.
Abstract
This document describes a filter reflection image guide oscillator and a solid state line scanning device. The device includes a brass metal heat sink base on which a dielectric waveguide is mounted. A resonant cavity is defined in the dielectric waveguide and an oscillator diode, Gunn or IMPATT, for example, is located in the resonant cavity. The resonant cavity is enclosed by a metal cover with a post which is made to extend into the resonant cavity to contact one electrode of the oscillator diode. The top surface of the waveguide includes a perturbation surface consisting of parallel and spaced metal stripes which are laterally positioned along the length of the waveguide. The spacing of the metal stripes defines the function performed by the device. By changing the bias voltage of the oscillator diode or with the addition of a varactor with a separate DC bias source, the frequency in the waveguide can be changed and thus line scanning or beam steering is made possible.
