China 1GHz Outdoor Bi-Directional CATV Signal Amplifier (WA1300CEAM)

Product Description

We are professional manufacture in CATV line in China, we offer CATV splitter, CATV amplifier, CATV optical receiver, CATV optical transmitter, CATV optical optical switch, EDFA and CATV modulator and so on.

Feature

1.New developed high-gain amplifier
2.Bi-directional trunk amplifier
3.Plug-in,convenient to debug
4.GaAs module,many options

Performance Characteristics

1 The forward path preceding stage adopts the newest high index imported low noise push-pull amplifier module or GaAs push-pull module, output stage adopts the newest high index imported power doubly amplifier module or GaAs amplifier module. The nonlinear index is good and output level is more stable. The return path adopts the newest high index imported return dedicated amplifier module. The distortion is low and the signal to noise ratio is high.
2 It is more convenient to debug because of the plug-in duplex filter, plug-in fixed (or adjustable) equalizer and attenuator, and the scientific and reasonable on-line detection ports.
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.
4 The shell adopts embedded modular design; equipment maintenance, replacement, and debugging are convenient.
