BSF0021F1V1-1

TWIN BANDSTOP 900MHz FILTER

The BSF0021F1V1 is ideal for co-located 850 and 900 networks. Utilising a 2.5MHz guardband the BSF0021F1V1 provides rejection of the 850 band while passing 900 UL and DL bands. Capable of being used in an outdoor environment the BSF0021F1V1 contains two identical bandstop filters, suitable for 2x2 MIMO configuration, offereing excellent insertion loss, group delay, EVM and rejection.

FEATURES

  • Rejection of 850MHz downlink
  • Passes full 900 band
  • Notch filter structure
  • DC/AISG pass
  • Low insertion loss
  • Outdoor and indoor configurations
  • Twin unit
