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.
