Octave Bandwidth Photonic True Time Delay Beamformer for SKA Demonstrator  
   

Conclusions

  • Beam points in the same direction for all frequencies
  • Switched delay lines plus optical addition is broadband
  • Octave bandwidth RF-to-optical interfaces: 1.8 - 3.5 GHz
  • Spurious Free Dynamic Range: 101 dBHz2/3
