BSF0020F3V1-1

BSF0020F3V1-1

TWIN BANDSTOP 900MHz INTERFERENCE MITIGATION FILTER

The BSF0020 is ideal for co-located 700, 850 and 900 networks. Utilising a 2.6MHz guardband the BSF0020 provides rejection of the 900 UL band while passing 700/850 UL and DL bands. Capable of being used in an outdoor environment the BSF0020 contains two identical bandstop filters, suitable for 2x2 MIMO configuration, offering excellent insertion loss, group delay and rejection.

FEATURES

  • Passes full 700 and 850 bands
  • Low insertion loss
  • Rejection of 900MHz uplink
  • DC/AISG pass
  • Twin unit
  • Dual twin mounting available
