TWIN TMA AWS/PCS DUAL BAND WITH LOW BAND BYPASS
Designed to be deployed in co-located AWS, PCS and low band systems with wideband antennas, this Tower Mounted Amplifier provides internal duplexing in all three bands with uplink gain in the high bands. A passive Tx/Rx path is provided to a low-band antenna port, thereby saving capital expenditure and tower leasing fees.
FEATURES
- Improved base station sensitivity through gain in the AWS and 1900 uplink bands
- Highly integrated unit available as a twin unit (4 antenna ports) or as a quad unit (8 antenna ports) to suit 4×4 or 8×8 MIMO systems
- Excellent noise figure performance
- Internal duplexing of 617-894MHz signals to be passed to additional ANT ports
- Internal duplexing of AWS and PCS bands
- AISG2.0 compatible
- Compact, low weight
