• 1GHz Outdoor Bi-directional Trunk RF Amplifier
  • Model Number: SA1012
  • Brand: SOFTEL
  • MOQ: 1 PCS
 

Quick Detail:

●Forward path use import low noise push pull amplify module or GaAs push pull module,2 Power-Double module or GaAs amplify module are used as output stage, Output level is stable and nonlinear index is good, import high index amplify module are used on return path, It's distortion is little and SNR is high.
●It is more convenient to debug because of plug-in(or adjustable) duplex filters, plug -in fixed(or adjustable)equalizers, plug-in output splitters and scientific and rational on-line detection ports.
●The equipment can work steadily outdoor under bad environmental condition because of waterproof aluminum case, high reliability switching power supply and lightning protection system.
