Abstract

A hybrid coupler is of the type known as a transverse electromagnetic mode, coupled transmission line coupler. The hybrid coupler is formed within a plate of metal by milling out channels of square cross-sections therein. The walls of the channels serve as outer conductors of coaxial lines, there being inner conductors of square cross-section positioned within the channel. A diagonally disposed window crosses the intersection of the ports and includes a separator. The central conductors of the respective coaxial lines are joined by diagonally disposed segments of inner conductor such that each pair of coaxial lines is so joined. Each pair of lines provides a pair of ports. The line segments are spaced apart by a spring-loaded separator for rigidly maintaining a coupling distance.
