Digital Receiver and Exciter (DREX)

Digital Receiver and Exciter (DREX)

Cobham Advanced Electronic Solutions’ high performance, modular and extensible Digital Receivers and Exciters (DREX) solutions – known as Mantella – are used in ground, sea, and air AESA/phased array radar systems.



  • Scalable from modest to large scale radar systems
  • Waveform generation (linear frequency modulated or chirp pulse, arbitrary)
  • Enable active electronically scanned array (AESA) radar system architectures to:
  • Implement transmit / receive (T/R)  module and integrated line replaceable unit DREX functionality (frequency synthesizers, multi-channel frequency converters, exciters and controllers) close to the element level
  • Create high-resolution, wideband waveforms
  • Provide peak performance for long range, high sensitivity and multiple beam detection and tracking
  • Ku- and S-band solutions today.  Building blocks available for X- and C-band.

Enabling Technology:

  • Multilayer RF circuit card assembly
  • GigE, 10 GigE and fiber output options:  OC-48, OC-192, OC-768
  • Baseband processing/generation
  • Data rate capacity
  • Low phase noise waveform generators
  • High dynamic range

Unique packaging techniques allow for high circuit density, high isolation, excellent thermal management, small size, and low weight.
