Multi-Hole Directional Coupler
It is a four port waveguide junction consisting of primary main wavelength and a secondary auxiliary waveguide. They can Sample a small amount of microwave power for measurement purpose. They are designed to measure incident and reflected power, SWR Values, provide a signal path to a receiver or perform other desirable operations. The coupling is done through holes on the broad side of the waveguide. The diameter in the no of holes in a row and the number of rows vary according to coupling sector required. Scientific Microwave offers 3dB, 10dB, and 20dB couplers to its customers with minimum VSWR.
