Recently HUBER+SUHNER Hans developed A 67 multi coaxial RF backplane connecting system , this system is intended for side by side implementation of Vita 46 and beta 66 hardware system.
These devices are basically flexible and of very high density under military applications for ground base station or communication systems that have critical frequency applications. Insertion loss depends on the cable selected for the application while maximum VSWR at 40GHz is 1.55:1 and 1.75:1 at 65GHz. Operating temperature range is -65 to +155°C.
