DIPLEXER 700/850-900
The Kaelus DBC0157 is a bi-directional diplexer designed to combine 700 and 850-900 technologies. The DBC0157 provides low insertion loss and excellent passive intermodulation performance. The DBC0157 can be used at either the BTS or antenna end of the feeder.
FEATURES
- Enables antenna/feeder sharing for 700 and 850-900 networks
- Low insertion loss & high return loss
- Low passive IM performance
- Multiple DC/AISG bypass configurations available with built-in lightning protection
- Single and twin models available
