Detailed product information

Base power amplifier system consists of power amplifier and tower amplifier

BPA, the ultra-linear frequency selection amplification equipment installed on base station, consists of ultra-linear power amplifier, high performance duplexer, low-noise amplifier, electronic attenuator, frequency selector, corresponding monitoring unit, and power supply system. It is used to enhance the power grade of base station and enhance the coverage effect. TA is used to amplify uplink signal, enhance the receiving sensitivity of base station, and ensure the balance of uplink and downlink for the convenience of good connection between mobile and base station.
