The E connector closes the gap between the well-established 1.85 mm coaxial connector (the V-band connector) and the 1.00 mm connector (the W-band connector). The V-band connector, introduced more than 30 years ago, is suitably robust for industrial applications, but is restricted to a maximum frequency of 70 GHz. The W-band connector, on the other hand, supports a maximum frequency of 110 GHz, but requires a fine-mechanical accuracy during assembly, and frequently loosens in use.
Daniel Blaschke, head of development for RF & Microwave Power Meters at Rohde & Schwarz, says: “Power sensors are often the first T&M instruments for which customers request native support of a new connector type. We are happy to be the first to introduce a model equipped with the novel E connector, thanks to this fruitful partnership.”
Dr. Hans-Ulrich Nickel, head of RF Research & Development at the SPINNER Group, comments: “We initiated the 1.35 mm project to obtain a robust and future-oriented interface up to 90 GHz.”
Hauke Schütt, Executive Vice President Test & Measurement from Rosenberger, adds: “The new 1.35 mm connectors draw a lot of interest in the 70 to 90 GHz range.”
Dr. Karsten Kuhlmann, head of the working group High-Frequency Basic Quantities at PTB, says: “International standardization and traceability to national standards are key ingredients for the successful introduction of a new RF connector system.”
