TWIN TMA 700, LOWPASS
Designed to be deployed in 700, 850/900MHz shared antenna systems, the Kaelus TMA2094 provides gain at the 700MHz uplink band while allowing 850/900 services to pass through to the antenna thereby saving OPEX and CAPEX.
FEATURES
- Improved base station sensitivity through gain in 700Mhz band
- Bypass for 850/900 bands with internal diplexing of the 807-960 and 700MHz bands
- Rejection of digital TV broadcast channels
- Hardware and software configuration using AISG “Personality” upload
- Fail safe bypass mode with lightning protection
- High linearity and low noise performance
