33dBm Single Band Line Amplifiers

Product Feature:




33dBm output, small and elegant appearance.

Good heat dissemination design.

Work with indoor repeaters to expand coverage.

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

Coverage up to 1000~3000 m².

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

     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
