Kaelus: Twin Same Band Combiner, CDMA850 A'/B' + LTE700/LTE850 A/B-Bands
Designed to combine LTE700/LTE850 radio(s) with legacy CDMA850 equipment, the Kaelus DBC0134 is a low loss twin combiner with excellent insertion loss and passive inter-modulation performance.
- Combines/splits legacy CDMA850 & LTE700H/LTE850 A/B-bands
- Supports 10MHz LTE expansion in 850MHz A and/or B-bands
- Allows LTE700/LTE850 & CDMA routing to separate antennas
- Ideal for use with dual band LTE700 & LTE850 radios
- Supports CDMA channels placed in either A' or B'
- Extremely close (zero guardband) spacing
- Designed for low passive inter-modulation
- DC/AISG autosensing with LED status
- Low insertion loss
