A Waveguide Switch Employing the Offset Ring-Switch Junction

This paper describes an X-band microwave ring switch employing a junction of new design. The insertion loss is less than 1/4 db over the design band of 9.0-9.6 kmc; this low loss was obtained through the use of a coupling junction which is designated the offset ring-switch junction. A physical description, the electrical characteristics of the switch, and a qualitative theoretical discussion of the junction are included.
