Product Details

Bidirectional CATV Line Amplifier

Product Application

The main role of two-way user amplifier WS-SXG302 is compensated transmission cable TV signal attenuation

caused by the process, to ensure the signal can be stablized, high quality, long-distance transmission. It

should also have a role in the balance with the curve.

SXG302 user amplifiers are mainly used in all kinds of two-way cable modem CATV systems, satellite television systems,residential CCTV surveillance system, hotel audiovisual systems, as well as military units,

schools and other educational audio-visual systems.

Performance Characteristic

1. High quality waterproof and dustproof aluminum shell with good shielding performance and heat dissipation.

2. Dual epoxy boards with mount technology(SMT),stable and reliable performance.

3. High quality duplex filter,split point is optional.

4. Forward amplifying circuit adopt one modules to enlarge.

5. Low-noise push-pull amplifier module, make sure the noise indicator of equipment;

6. Adjustable attenuator and equalizer in forward and reverse path,equipped with two balancing attenuation

adjustment,effective solution to the level of "bulge" phenomenon, can make the output level with slope,

be applicable to the cable transmission over a long distance.

7. RF test port in reverse path (-20dB).

8. Two outputs, Changeable tap or splitter.

9. High-reliability linear and switching power supply,220V/60Vac
