Help for Frustration in Testing Labs
1.00 mm coaxial connectors are standard in RF labs worldwide. In fact, they are must-haves for engineers who perform measurements in the range up to 110 GHz.
Lower Friction – Higher Precision
A bearing of the coupling nut prevents friction on the outer conductor. The outer conductor is no longer turned simultaneously – rotation stability is guaranteed.
The SPINNER EasySnake performs the function of a flexible dielectric waveguide.
Articulated lines boast excellent RF properties and an extremely long service life. They are considerably more robust than ordinary test cables, lasting several times as long.
SPINNER rotary joints excel with compact designs, excellent VSWR, low insertion losses, minimal fluctuation of transmission characteristics while rotating.
Start testing faster with these new adapters from SPINNER. They save time with ruggedized coaxial interfaces for directly connecting millimeter waveguides to the coaxial ports of mmWave VNAs. Ultralow losses are guaranteed.
In lab environments, you need to have the right interfaces handy: for waveguide-to-coaxial or coaxial-to-waveguide transitions and with male or female coaxial connectors as required. These convenient solutions save time and let you focus on your testing work.

A common frustration in RF laboratories is unwanted unlocking of the 1.00 mm coaxial thread performing time-consuming calibrations. This spawned the idea of a 1.35 mm connector the “E Connector” with a precise metric thread like the 1.85 mm connector plus an integrated time-saving push-pull capability.
SPINNER 1.35 mm - E Connector: Adapters
1.00 mm coaxial connectors are standard in RF labs worldwide. In fact, they are must-haves for engineers who perform measurements in the range up to 110 GHz. However, their conventional design suffers from a problem: the pitch is too coarse, i.e. the axial distance between the threads is too great.
They resemble the self-tapping screws sold in hardware stores, with a crucial difference: whereas self-tapping screws do their job reliably and withstand typical vibrations with ease, the nut that mates with a 1.00 mm connector loosens practically from being looked at. Calibration problems are therefore literally built-in, often making it necessary to repeat entire test series. Besides the unnecessary extra costs this incurs, it’s a major source of frustration.

For labs that depend on the use of 1.00 mm connectors, we offer a 1.00 mm ruggedized test port adapter that even works with one-millimeter coax connections. It uses a larger thread to achieve a secure mechanical lock. Unintentionally applied transverse or torsional forces are reliably blocked to prevent them from damaging the delicate 1.00 mm coaxial connection. As a result, once a test setup has been assembled and calibrated it can be depended on to consistently do its job as intended.

Classic waveguides are typically rigid, which places considerable constraints on the design of test configurations. The SPINNER EasySnake overcomes this by combining the flexibility of a conventional RF test cable with the excellent low-loss transmission characteristics of a conventional waveguide system. It can be flexibly bent and moved in any direction while delivering excellent measurement results.

SPINNER rotary joints excel with compact designs, excellent VSWR, low insertion losses, minimal fluctuation of transmission characteristics while rotating, and high crosstalk attenuation between individual channels across the entire range of frequencies used.
Noncontacting RF rotary joints (RJ) are available in coaxial and waveguide designs for frequency ranges up to 100 GHz. They are characterized by an especially long service life. Signal transmission is possible at a bandwidth of about 20% of the highest transmitted frequency.
Noncontacting rotary joints are used for narrow-band transmission. With special coupling structures, the same module can also be used to transmit two different frequency bands (e.g. the X and L bands).
In contacting rotary joints, the inner and outer conductors of the stator and rotor are DC-coupled.The maximum frequency depends on the diameter of the coaxial line. These coaxial rotary joints are used for broadband applications, allowing signal transmission in the frequency range from DC up to 120 GHz.
