Application Diagram

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
