The design and testing of integrally constructed waveguide assemblies

Problems associated with integrally constructed waveguide assemblies are discussed, the advantages of this form of construction are shown, and suitable components and methods of construction are described. Complex assemblies of this type present special testing problems which are solved by employing a plug-in reflectometer, together with a swept-frequency reflection display. These principles are applied to a typical microwave link repeater, and the alignment of the signal-input section is described in detail. An overall performance with less than 2% reflection is confirmed by independent measurement. A swept-frequency display receiver of high sensitivity is needed for display; the design is briefly described and used to illustrate another example of integral construction.
