It was developed at Hewlett-Packard in 1989 by Paul Watson. The requirements on production are very high, in keeping with the small dimensions.
Even the smallest deviations are immediately noticeable in the characteristics as the following values show.
Tolerance of 0.005mm 49.05Ω - 51.03Ω
Tolerance of 0.010mm 48.07Ω - 52.03Ω
The union nut also has a metric thread (M4 x 0.7) but is smaller than that of the 2.4mm and 1.85mm. This prevents it from being paired with the 2.4mm or 1.85mm is paired.
Precision 1.0mm series connectors have 50 Ω impedance and outer conductor diameter of 1.0mm. This connector series is used for the new demanding test and measurement applications up to 110 GHz.
The connector series 1.0mm meets the highest level of reliability and repeatability in the spectrum of the highest bandwidth. The interface is standardized according to IEC 61169-31 and therefore mate compatible with all common 1.0mm connectors.
The elspecgroup product portfolio includes flexible coaxial cable assemblies, semirigid cable assemblies, PCB connectors and waveguide coaxial adapters.
Features in short form:
+ Interface according to IEC 61169-31
+ Frequency range up to 110GHz
+ Air dielectric with PEEK supports
+ Cable groups: UT-047/ Stormflex047EW
