• 860MHz CATV Indoor Bi-directional Amplifier
  • Model Number: SA801H
  • Brand: SOFTEL
  • MOQ: 1PCS
 

Quick Detail:
 
●The microwave low noise amplification circuits or RF modules encapsulated by SOT-115 for CATV are used as forward paths. Output level is stability, and nonlinear index is good.
●The microwave low noise amplification circuits with little distortion and high SNR are used as backward paths.
●It is more convenient to debug, because of plug-in duplex filters, adjustable equalizers, adjustable attenuators, plug-in output splitters and scientific and rational on-line detection ports.
●The equipment can work steadily outdoor under bad environmental condition, because of high reliability linear power supply and lightning protection system of good-looking aluminum alloy shell with good heat dispersing performance.
 
 
Description:
 
SA801H Indoor Bi-directional Amplifier are special amplifiers designed for the last”1km” of the bi-directional transmission network. Special CATV RF modules packaged in SOT-115  are used as forward channel; Microwave tube push-pull circuit with low noise are used as backward channel ;It has the characteristics of low power consumption,high reliability and excellent cost performance. And it is suitable for small and medium sized CATV bi-directional transmission network.
 
 
Applications:
 
●CATV System
●HFC network
