533431 OSLT Compact calibration kit, 70GHz, 1,85mm(f), 50 Ohm

Spinner BN: 533431 Open / Short / Load / Through (OSLT)  Compact calibration kit (4-in-1), DC – 70 GHz, 1,85 mm (female), 50 Ohm

The OSLT compact calibration kit (4-in-1) DC-70 GHz 1.85 mm female has a characteristic impedance of 50 Ohm.
It is characterised by very low VSWR and attenuation values as well as best intermodulation properties in the entire operating frequency range from DC to 70 GHz. The test kit has 5 interfaces with 1.85 mm female.

This product has gold-plated connections and is based on the better quality classes of the IEEE, ICE standards with regard to lower tolerances.
SPINNER also uses the term ‘precision’ here to emphasize the suitability for exceptionally high-precision measurements.

The 1.85mm connector was first proposed and introduced in 1986 and soon used on Vector Network Analysers. The 1.85 mm coaxial connector has an air-filled dielectric interface.
1.85 mm precision connectors are particularly suitable for use in radio-frequency test and measurement laboratories for frequencies up to approx. 70 GHz.
They are designed with excellent characteristics and tight tolerances over the entire specified frequency range. They are an advancement of the coaxial 2.92-mm connector size and are known as Type-V connectors.
