Khuếch Đại Prevail WA1300-CEAM

WA1300CEAM series outdoor bi-directional trunk amplifier is the new developed high-gain amplifier. Mature and optimized circuit design, scientific and reasonable internal process and high quality materials, ensure the stable gain and low distortion. It is the best choice for building large or middle-sized CATV bi-directional transmission network.

Performance Characteristics

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.
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.
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.
The shell adopts embedded modular design; equipment maintenance, replacement, and debugging are convenient.
