TWIN TMA 1800/2100
Designed to be deployed in co-located 1800 & 2100MHz systems with wideband antennas, the Kaelus TMA2053 provides internal diplexing and gain in both bands, thereby saving hardware costs.
FEATURES
- Improved base station sensitivity through gain in the 1800 and 2100 uplink bands
- Hardware & software configuration using AISG “personality” upload
- Excellent noise figure performance
- Internal diplexing of 1800 and 2100MHz bands
- AISG2.0 compatible
- Compact, low weight
