Millimetre wave connectors are designed for use in 50 ohm systems, and operate in the frequency ranges up to 110GHz (dependant upon series). The connectors are designed to have a low VSWR and return loss.
The construction of these devices ensures that the body engages before the centre conductor, and allows for a rugged and reliable mating interface. The interface is an air dielectric, with the contact supported by a short glass bead.
All connectors can be configured to be terminated with flexible or semi-rigid cables.
The series designation refers to the outer conductor diameter and generally, the smaller the outer cable the higher the maximum operating frequency as detailed below:
- 3.5mm max operating frequency 34GHz (mechanically compatible with 2.92mm and SMA connector series)
- 2.92mm max operating frequency 25GHz (mechanically compatible with 3.5mm and SMA connector series)
- 2.4mm max operating frequency 50GHz (mechanically compatible with 1.85mm connector series)
- 1.85mm max operating frequency 65GHz (mechanically compatible with 2.4mm connector series)
- 1.0mm max operating frequency 110GHz
