Standard waveguides and couplings for microwave equipment

An account is given of the development and standardization of waveguides, couplings and adaptors for microwave equipment. Whilst these items were primarily intended for use in Service electronic equipment, they have proved to be of considerable use in commercial applications. The appropriate sizes of waveguide to cover the whole microwave spectrum are discussed, and reasons are given for the standards chosen. The final specifications are the result of much interchange of information amongst users of equipment in this field, not only in this country but in others. A Section on the finishing and packaging of waveguide parts is included.
