Description:
Bidirectional Tower Mounted Amplifiers (BTMA) is equipment that amplifies the primary base station uplink and downlink signals at the same time. Its main functions are as follows:
1. Enhance the level strength of uplink and downlink, boost up deepness and extent coverage ranges.
2. By amplify the uplink signal to debase noise of base station receiving system, enhance sensitivity.
3. Debase dropping rate and handoff rate, enhance talking quality.
4. Increase traffic, enhance economy benefits.
5. Debase mobile phone output power, purge electromagnetic environment.
Series:
Our products, covering from common communication 2G frequency(CDMA450, CDMA800, CDMA1900, GSM, EGSM, GSM1800, GSM1900, DCS, PCS, WLAN), 3G frequency(WCDMA, UMTS, CDMA2000), Trunking Communication(TETRA, iDEN, GoTa, GT800, 350Mhz Police Communication), Railway Communication System(450MHz Radio Train Dispatch Communication Series, GSM-R Series), Military Communication, FM Broadcast Communication, UHF, VHF Interphone Communication, Marine Communication, Sea Area Coverage Systems, output power can be chose from 40W(46dBm)to 200W(53dBm).
Product Features:
1.Realize plug-pull independently, online maintenance, convenient for installation.
2.Have remote wireless monitoring, adjust the TMB parameters via messages.
3.Adopting advanced LDMOS power amplifier with highly linearity and low intermodulation, the linearity and intermodulation indexes of whole machine are excellent
4.power of per carrier frequency set independently, large output power, high signal quality and high performance price ratio.
5.provide multifold power connection (220V, 48V, 24V).
6.Automatic bypass function, while input power temperature or standing wave is too high, the equipment will bypass automatically to protect equipment, and give a warning at the same time. Then the fault information could reported timely, convenient for timely maintain.
7.Crate accord with IP55 protection and high heat-dissipation design, able to work outdoor all-weather
8.Overall product series and perfect power grade to satisfy different requirements of network coverage
9.can realize networking with multifold base station types(such as: Ericsson, Alcatel, Nokia, Hua Wei, Simon, etc) through different PDU.
