Abstract:

Directional couplers possess properties which make them useful for power monitoring purposes and for impedance measuring or matching. The action of a number of different general classes of directional couplers is explained qualitatively. Characteristics of specific types in both waveguide and coaxial line are given, together with information necessary for the design of these couplers to meet particular requirements. The emphasis in this report is upon directional couplers such as might be used as test points in radar systems at which one can monitor transmitter power and introduce signals of known amplitude to measure receiver sensitivity.
