Abstract

1276050 TR switches; waveguides WESTINGHOUSE ELECTRIC CORP 9 Nov 1970 [31 Dec 1969] 53196/70 Headings H1D and H1W A microwave TR switch for a radar system comprises a pair of electrodes 10, 11 extending from the broad walls 12, 13 of a section of rectangular waveguide 5 to define a discharge gap 19 in which there is disposed a capillary tube 26 containing an ionizable gas so as to lie within a static magnetic field produced by magnet 28, the field lines from which are parallel to the electric vector of the H 01 mode microwaves propagated in the waveguide. The capillary tube which may be of quartz or sapphire and contain for example Cl 2 or HCl at a pressure of 5-15 torr, extends across the discharge gap and is disposed within a bore passing through the upper electrode 10 and the upper leg 28a of the magnet where it terminates in a reservoir (not shown). Extending inwardly from the narrow walls of the waveguide are vanes 14, 16 which form a tuned iris. The iris constitutes the inductive portion of the tuned circuit and the two electrodes the capacitative portion. A high power E.M. wave, preferably the dominant TE 01 mode, produces a high inter-electrode voltage causing ionization of the gas and a current discharge within the capillary tube. The magnetic field is thought to cause the discharge electrons to move in helical paths thereby reducing electron loss at the wall of the capillary tube and extending the electron life-time such that when the radar is operated with a long inter-pulse period enough electrons remain after one pulse to facilitate the subsequent discharge breakdown.
