About the HN Interface

The HN interface is a modified type N interface with overlapping dielectrics that provide greater power and voltage capabilities in a moderate line size. The modified interface does degrade the operating frequency of the standard type N interface to 4 GHz maximum. HN connectors are commonly used in high power industrial applications for etching sputtering and wafer processing equipment.
