Coupler

Application Guide

Directional coupler is commonly used for sampling microwave signals in specified flows. In the absence of the load, directional coupler is usually a 4-port network. Generally adopting parallel coupling lines, the length of coupling zone is an integral multiple of one-fourth wavelength. Coupler's direct output is not adjacent structurally to the coupling port, with discrepancy of output phase of 90 degrees or 180 degrees. The remaining port is called isolation port, which does not export any energy theoretically.

Product Name:
Cavity Coupler
Model:
LP-SC05/06/07/10/12/15/20/25/30/40 0825B
Description:
Directional coupler commonly used for sampling the microwave signal with the given flows. Absence of the load, the directional coupler is always the 1/4-port network. Adopting the parallel Coupled lines, the coupled zone length is integer multiple comparing the fourth wavelength, and its output port is non-adjacent with the coupling port on the structure, the output phase discrepancy is 90 degrees or 180 degrees, the remaining port which is called isolation port is not output any energy theoretically.
