DDF0019F2V2-1

TWIN DUAL DUPLEXED FILTER 850

Designed as an 850MHz Transmit filter the DDF0019 is used to attenuate spurious emitting from a 850MHz Base Station over and adjacent 900MHz RX carriers.

FEATURES

  • For use in 850MHz applications with 900MHz co-location
  • Low downlink insertion loss while attenuating spurious outside the 850MHz transmit spectrum
  • DC pass configured for use with Tower Mounted amplifiers
  • Economical twin filter solution
  • Suitable for retuning to bandwidths of 10-18MHz with guard bands >4MHz
