SMA Hybrid Couplers

A 90 degree hybrid coupler is a four-port device used to equally split an input signal into two signals with a 90 degree phase shift between them. The 90 degree hybrid coupler can also be used to combine two signals while maintaining high isolation between them.

Electro-Photonics LLC offers high performance connectorized couplers in a very small, compact package. Our SMA hybrid couplers have low insertion loss and VSWR, and high power capability. These hybrid couplers are suitable for various applications such as signal splitting/combining, antenna beam-forming networks, RF amplifiers, test & measurement, and more. 

We can custom design to your specifications. 

We also offer surface mount technology hybrid couplers.
