Octave Bandwidth Photonic True Time Delay Beamformer for SKA Demonstrator  
   

Design

Advantage Photonics
  • Broadband beamforming
  • Low loss delay lines
  • No electro magnetic interference
  • Beamforming and antenna can be separated over large distances
 
Disadvantage Photonics
  • Interconnection technology requires precise alignment or is bulky
  • RF-to-optical (and vice versa) interfaces are inefficient
