Dual Polarized Probes

TECHNICAL PERFORMANCE

  • Dual linear polarization with high on-axis polarization purity and isolation
  • Mono-mode excitation on a 1:3 bandwidth
  • Radiation pattern dominated by first-order spherical modes (allowing for first-order probe correction)
  • Low return loss / VSWR

DESIGN

  • Wideband orthomode junction (OMJ) based on inverted quad-ridge circular waveguide with external feeding circuits, feeding a circular aperture

SURFACE TREATMENT

  • Surtec 650 according to MIL-C 5541E class 3
  • Polyurethane paint

REPEATABILITY

  • Stiff and robust mechanical design
  • Precision machined
  • Standard MVG circular interface for precision centering
  • Precision guiding pin for accurate polarization alignment
  • High reliability RF components

DELIVERED DOCUMENTS

  • Typical performance data (TYMEDA™)
  • Measured return loss data and port-to-port coupling

EQUIPMENT

  • Mounting flange
  • Removable absorber plates
  • Integrated polarization switch (Optional)

RELATED SERVICES

  • Calibration and maintenance (Optional)
  • Customization (Optional)
