PLB connectors are designed for applications up to 6 GHz, as required by today's and tomorrow's radio base stations.

The interface is based on the SMA dimension, but instead of a threaded coupling mechanism a new pushing on the method is used. The PLB interface has a very similar performance to the SMA, but in addition it offers an easier, faster and saver coupling operation The plug connector is strong in the chape in the closed entry structure.
