1. Summary

SNP8028-00, SNP7028-00, SNP8130-00, SNP7130-00 Field Bidirectional Subscriber's Amplifiers are designed specifically for last “1km” of CATV bidirectional transmission network. These amplifiers with good indicators, low power consumption, high reliability and high performance cost ratio are suitable for medium and small-scale bidirectional CATV transmission network.

2. Performance Characteristic

The microwave low noise amplification circuits are used as forward and backward paths of SNP8028-00 and SNP7028-00 products. CATV special RF modules encapsulated by SOT-115 are used as forward paths of SNP8130-00 and SNP7130-00 products. The microwave low noise amplification circuits are used as backward paths of SNP8130-00 and SNP7130-00 products.

It is more convenient to debug, because of plug-in duplex filters, plug-in fixed (or adjustable) equalizers, plug-in fixed (or adjustable) attenuator 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.
