GSM Truck/Line Amplifier
GSM Truck/Line Amplifier
Trunk amplifier belong to the same frequency amplifying device, it is to point to play in the process of wireless transmission signal enhanced via a radio transmitting equipment. Through the erection of repeater station can not only improve the covering effect, can greatly reduce the investment cost of base station at the same time. Trunk amplifier coupled through the BS port mobile communication base station downlink signal, through selective bandpass filter for excellent isolation outside passband signals, after power amplifier amplification by resending antennas to the coverage, at the same time in the uplink path, covering the area of mobile station signals in the same way of working by upward amplification to the corresponding link after launch base stations, to realize the seamless link of mobile communication base station and mobile station, so as to achieve the purpose of extending coverage
According to the power level is divided into: 1 w, 2 w, 5 w, 10, 20, 30 watts
According to the communication system is divided into: TETRA, IDEN, GSM, DCS, CDMA, WCDMA, UMTS, td-scdma, LTE TDD, LTE FDD, Wimax, Wifi, multiple formats fusion all-in-one
According to the feature points: wide band trunk amplifier, channel selective trunk amplifier
