DDF0015F5V2-1

TWIN DUAL DUPLEXED FILTER E900

The DDF0015 is deployed when co-locating 900 and 850MHz systems. Attenuating the 850MHz downlink band this filter prevents the 900MHz BTS receive being overloaded from 850MHz systems.

FEATURES

  • Filters unwanted carrier frequencies introduced when antennas from both 850 and 900MHz services are co-located
  • Twin dual duplex structure.
  • Excellent rejection in 850MHz band, low loss, high selectivity
  • Factory tuned anywhere in extended 900MHz band if required
  • DC Pass available
