Rosenberger RPC-7 “hermaphroditic” connectors with 7 mm diameter at outer contact are designed for precision measurements up to 18 GHz and are suitable for semi-rigid cables and microwave components. Mating electrically with center and outer conductor by end-surface (butt) contact, the mechanical connection is designed as a counter-sinkable threaded socket. For total flexibility, these low reflection connectors are intermateable with all common 7 mm series connectors including APC-7, PC-7, GPC-7 or Precifix AA. Furthermore, RPC-7 and RPC-N connector heads are interchangeable using the same bead type.

The wide product range comprises connectors and connector heads, adaptors, interchangeable port connectors, airlines as well as test & measurement accessories such as RPC-7 calibration and verification kits, test cables, attenuators or measurement equipment (open – short – load).
