1GHz outdoor Bi-directional catv amplifier catv trunk amplifier

Down broadband up to 1GHz, it is the good choice for large NGB network.

1. Summary

SNP1100KL-00 Field Bi-directional amplifier is the upgrade version of SNP8130KL, Down broadband up to 1GHz, it is the good choice for large NGB network.

2. Performance Characteristic

1000MHz Broadband

GaAs MMIC used on the forward path, Power-Double module 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, its 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.
