Open Waveguide Probe (QAP Series)

  • Rectangular open ended waveguide with single flange
  • Standard waveguide sizes from 8 GHz up to 325 GHz
  • Tapered waveguide end to minimize diffraction
  • Custom lengths available

QuinStar Technology's QAP series open waveguide probes have been carefully designed to perform near-field measurements. These probes are compatible with many standard waveguide sizes and can operate over a large range of  frequencies. The probe's open ends are tapered in order to minimize wave diffraction. Probe length is customizable to suit your application.
