The 1.35 mm Connectors (also known as E Connectors) has been developed by a working group, consisting of PTB (Physikalisch Technische Bundesanstalt), Rosenberger, Rohde & Schwarz and Spinner to close the gap between 1.85 mm and 1.00 mm connectors. The 1.35 mm connector can operate up to 90 GHz and features a highly robust mechanical design which can support over 3000 mating cycles, has high connector repeatability and excellent return loss values. The standardization of the 1.35 mm interface is currently in progress for IEC (IEC 61169-65) and for IEEE (IEEE Std 287). The new 1.35 mm connectors are ideal for high-performance RF measurements, self-driving vehicles, and 5G applications.
