Further Development of an Electronically Controllable Microwave Window.
Abstract
The main objective of the research study was to further develop electronically controllable S- and X-band microwave windows. Results of the calculations carried out for determining the microwave transmission properties of X-band windows are presented. These show that the windows should be 4 to 7 mils thick to achieve switching from 0.5 db to 15 db with a resistivity change from 300 ohm-cm to 1 ohm-cm. The photolithographic mask and waveguide mount which was fabricated for the implementation of the X-band windows are described. Inductive strips in the injecting line structure reduce the insertion loss to 0.3 db. The X-band measurements carried out to test the broad band and low insertion loss capabilities of the windows are presented. (Author)
