Khuếch đại nhánh 2 chiều ZHT (WA1300-00) C-LINK Phân Phối

1. Summary

WA1300-00 Field Bi-directional amplifier is the upgrade version of WA8200-00, Down broadband up to 1GHz, max gain up to 40db,it is the good choice for large NGB network .

2. Performance
- 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 aluminium case, high reliability switching power supply and lightning protection system.
