ERI Announces New Externally Terminated, Adjustable Directional Couplers at NABSHOW2018

Chandler, Indiana USA – April 3, 2018 – Electronics Research, Inc. (ERI) will show a new series of adjustable directional couplers that feature external terminations. This family of coaxial directional couplers that are adjustable and externally terminated. The orientation of any sampling port can easily be changed from forward to reflected by reposition the external termination load on the coupler.

These couplers are available in 3-1/8-inch, 4-1/16-inch, and 6-1/8-inch, 50-ohm, models, with flanged input and output connections. The 3-1/8-inch and 4-1/16-inch models are also available with an unflanged male connection at the coupler input. Models available with one to five adjustable couplers with Type N sample ports. One external termination load is supplied for each sample port. Directivity and coupling level are dependent on operating frequency. The design of this new product family is complete, and all items mentioned in this release are in current production.
