AN INVESTIGATION ON AN ELECTRONICALLY CONTROLLABLE MICROWAVE WINDOW.

The main objective of this research study is to develop an electronically controllable S-band microwave silicon window in order to overcome some of the limitations of junction-type diodes in microwave switching applications. In this report the facilities for carrying out S-band low and high power level tests on the microwave windows are described. The advantages of mounting the silicon window in a reduced height waveguide are indicated, and the details are given of the design of a S-band microwave transformer in order to match the reduced height waveguide to the standard height waveguide used in the microwave test set up. A description is given of the way the silicon window is mounted in the reduced height waveguide. The solution to the problem of determining the distribution of excess carriers is given and the results obtained are compared with the ones obtained in a previous report.
