MI-6970 Family of Waveguide Probes

MI-6970-WR187 web

MI Technologies’ open-ended waveguide probes are ideally suited for near-field measurements. These probes are used to sample the radiated electromagnetic field of an antenna under test while minimally perturbing the incident field and are designed for minimum VSWR, long-term stability and excellent repeatability.

downloadpdfThe MI-6970 family of waveguide probes cover standard waveguide bands and are offered with a variety of coax connectors or open waveguide flanges.

 

  • Rectangular open-ended waveguide
  • Coaxial-to-waveguide transitions available for probes below 50 GHz
  • Tapered ends to minimize diffraction effects
  • Standard MI Interface mounting flanges
  • Cost-effective for a variety of applications
