Dual Polarized CATR Feed for Cross-Polarization Reduction

3300 MHz - 18000 MHz

A novel CATR feed concept to significantly improve the cross-polar performance of any uncompensated CATR systems, such as side/corner-fed single reflector systems.

Provides wideband dual-polarized conjugate field matching, effectively cancelling the Geometrical Optics (GO) cross-polar component induced by the offset reflector of any single reflector CATR configuration.

TECHNICAL PERFORMANCE

  • Dual linear polarization with high on-axis polarization purity and isolation
  • No nulls in the forward radiation pattern
  • Low back-scattering
  • Wideband, low dispersion

DESIGN

  • Wideband orthomode junction (OMJ) based on inverted quad-ridge circular waveguide with external feeding circuits
  • Axially corrugated circular aperture
  • Minimum waveguide cross-section for low backscattering

SURFACE TREATMENT

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

REPEATABILITY

  • Stiff and robust mechanical design
  • Precision machined
  • Highly reliable RF components

DELIVERED DOCUMENTS

  • Typical performance data (TYMEDA™)
  • Measured return loss data
