Product Description

1 GHz Trunk Amplifier Outdoor RF Amplifier




Summary

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.

 Characteristics

1.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.
2. Built-in optimal designed high performance AGC control circuit, make the control more precise
and the signal operation more stable.
3. 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.
