Waveguide to coaxial transitions

Features & Benefits

These high-performance components are highly compact, usually mass minimised and ruggedized and include a variety of system friendly features.

The position of the connector can either be axial to the waveguide aperture (“in-line”) or at 90 degrees with respect to the waveguide aperture (“orthogonal).
Flange details can be customized to include almost any customer requirement.
Some devices are optimised for mass (reduced operating bandwidth) while others are broadband.
Devices are either directly coupled (the connector contact to device case has zero Ohms resistance) or are non-directly coupled (the connector contact to device case has >1MOhm resistance).

Contact our product experts to discuss your specific system requirements and custom configurations to meet your needs.
