SOFTEL SA822 Outdoor CATV Amplifier RF Amplifier
Products Description
I. Summary
SR822 outdoor trunk bi-directional amplifier is mainly used for bi-directional trunk transmission of CATV television image signal, digital TV signal, telephone voice signals and data (or compressed data) signal. Advanced and mature circuits, scientific and reasonable process structures and high quality materials, ensure the excellent performance. It is the first choice product to build the large or middle-sized CATV bi-directional transmission network.
II. Features
■ 1GHz bandwidth design.
■ Forward path: pre-stage adopts GaAs MMIC, output stage adopts the latest imported high index power doubler module, achieve high output level, low distortion and high signal to noise ratio.
■ It is more convenient to debug because of the plug-in duplex filter, equalizer, attenuator, output tap and the scientific and reasonable on-line detection ports.
■ 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.
