KA-6008-8433

3.7GHz BAND INTERFERENCE MITIGATION FILTER

The KA-6008-8433 is an interference mitigation filter tunable to two different positions: when set to position one, it rejects interference in the Satellite Communication Band (3820-3980MHz) band while passing 3700-3760MHz (A1/A2/A3 Block). When the Satellite Communication Band is vacated, the filter can be reconfigured to position two to pass 3700-3980MHz (A, B and C block). The change of configuration can be performed remotely via AISG. Capable of being used in an outdoor environment, the KA-6008-8433 contains eight identical filters, suitable for 8x8 MIMO configuration, offering excellent insertion loss and rejection.

FEATURES

  • Remote tunable filter set to 2 positions: position one, passing A1/A2/A3 block only, mitigates interference in the Satellite Communication band and position two allows the full 3.7GHz (A, B and C block) spectrum use, once the Satellite Communication band has been vacated.
  • Low insertion loss
  • Outdoor and indoor configurations
  • 8 in, 8 out configuration suitable for 8x8 MIMO configuration
