Wideband Flexible front-End Design for DTH Receivers

AUDENS ACT is leading a consortium comprising also Rheinmetall Defence Electronics GmbH (RDE) and RFEL in this ESA project that is looking for a future wideband flexible front-end architecture for DTH receivers

The major objectives of this activity are
  • to investigate in detail new architectures and technologies for the design of a wideband, highly flexible front-end as part of user terminals for next generation broadband and broadcasting services

  • targeting consumer grade products, to demonstrate the feasibility of a cost-effective solution with the capability to appropriately process

    • a single wideband carrier with a bandwidth of up to 500 MHz within a input frequency range of 1 GHz to about 5 GHz
    • multiple carriers from one or multiple input sources with an aggregate bandwidth of up to 500 MHz, which may exhibit individually different bandwidths.
The activity also aims at the investigation and demonstration of additional front-end processing to perform apart from
  • highly flexible digital front-end channelization/ digital filtering and carrier selection

  • signal level control and mitigation of front-end imperfections (I/Q imbalance, DC offset)

in particular,
  • digital beam forming and interference mitigation
