Summary

The EOSOL FEED-RAD-K-KA-DLP is designed to feed a refector at K and Ka band mainly for Earth Observation Radiometry applications. It provides very low spill over and therefore the feed offers low sidelobes level. This feed could be also suitable for telecom applications since it can be customized adjusting the frequency bands and parameters to the desired ones.

Applications

  • Radiometry
  • Aerospace
  • Ground stations

Key features

  • Frequency range: 18.6-18.8 GHz & 36-37 GHz.
  • Directivity: 18.8 dB (18.7 GHz) 22 dB (36.5 GHz)
  • Return loss 25 dB
  • Crosspolar values lower than -30 dB.
  • Dual linear polarization feed with very low spillover.
  • Low phase pattern variation and low phase center variation.
  • Can feed a Single Offset Reflector (offset/D = 0.6) with f/D between 0.8 and 1.25.
