Product Description

                      Bi-Directional Weatherproof Trunk Amplifier  with return pass RF amplifier

 

Product Description

SA1200 outdoor bidirectional AGC trunk amplifier is a new high gain amplifier. Adopt mature and optimized circuit design, scientific and rational internal process, high quality materials, and built-in high performance AGC control circuit, to ensure the stable gain and low distortion. It's the first choice equipment for large and medium-sized CATV bidirectional transmission network.

 

Features

 

• It is more convenient to debug because of the plug-in duplex filter, fixed equalizer and attenuator, plug-in output tap, and the scientific and reasonable on-line detection ports.
• Built-in optimal designed high performance AGC control circuit, make the control more precise and the signal operation more stable.
• The equipment can long time continuous work steadily under outdoor bad environmental condition. Because of the aluminum waterproof housing, high reliability switching power supply and strict lightning protection system.
