33 dBm Dual Band Line Amplifier

Product Feature:


Dust proof design, prolong equipment lifetime.

Support 2 system.

Work with indoor repeaters to expand coverage.

Reduce cellphone transmit power and radiation, extend cellphone battery life.

Coverage up to 5000~30000 m².

Low UL noise design, improve repeater sensitivity, keep communication quality.

Local and remote monitoring function (RS232/wireless modem).


Line amplifiers are actually applied as linear amplifier, it is used as the indoor coverage solution and must worked with mobile signal repeater. It amplifies transmitting RF signal in order to compensate signal loss by excessive cable or components. 


It is composed by two independent links: Uplink (or Forward Link) and Down Link (or Reverse Link). Downlink receives donor signals from BTS or Repeaters and amplify the donor signals; Uplink receives and amplifies signals from MS, in order to improve indoor coverage extension


Amplifier enhances consumer satisfaction greatly with its integrated design, compact size, easy engineering and rapid installation and debugging


Standard package 
   1) AC power cable (EU standard/ US standard/UK standard/ SA standard/China standard, etc) 1PCS 
   2) Installation kit 1PCS 
   3) User manual 1PCS
