Rohde & Schwarz to use new 1.35 mm E-band coaxial connector
Rohde & Schwarz has added the NRP90T and NRP90TN to its portfolio of thermal power sensors, releasing the very first test and measurement instruments into the market that support the novel, robust 1.35 mm precision coaxial connector.

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.”
