940 - 960 megacycle communications equipment for industrial applications

Discussions on the reasons for development,the technical details,and the application of microwave comunications equipment have been presented previously. A study of the schematics for these equipment will make it obvious that microwave equipment is made up of arrangements of parts which differ widely fom those normally encountered in electronic equipment for industrial applications. The purpose of this paper is to show why this difference exists. For example, it will be shown why a microwave receiver may need 20 or more tubes and a power-line carrier receiver may require only one tube. To illustrate why microwave equipment is different,an analysis will be made of portions of the Westinghouse type FB940 960-megacycle communications equipment.
