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
