Directional Couplers

MECA offers a wide selection of directional couplers designed to exceed commercial specifications. Standard coupling values of 6, 10, 20, 30 and 40 dB are available from stock. Custom configurations with special coupling values, external high power terminations and alternate connector styles or plating are also readily available in quantity. All models may be specified without an internal termination for bi-directional coupling. Passive intermodulation (PIM) compliant and weather resistant models are also available. With immediate access to our Application Engineers, you can choose the best product solutions for your specific needs. Made in USA.

Directional couplers are used in a wide variety of applications and can satisfy almost any requirement for sampling incident and reflected microwave power conveniently and accurately with minimal disturbance to the transmission line. Some general applications for directional couplers include line monitoring, power measurements and load source isolators.

When line monitoring, for the purpose of power level measuring and VSWR alarms, a directional coupler is used to sample power from the transmission line without altering line characteristics. In power measurements, insertion of a directional coupler in the transmission line allows measurement with simple low level detectors or field strength meters and power measuring equipment. By reversing the coupler in the transmission line, an indication of impedance match and/or reflected power can be derived by comparing the forward to reflected power levels. This may be more easily accomplished by using a dual directional coupler in the line. A signal can be taken from the source to the tap with high attenuation (directivity) between the tap and the load.
