WS-SXG402 Two-way Trunk Amplifier with Return Path

Two-way trunk amplifier WS-SXG402 is compensated transmission cable TV signal attenuation caused by the process, to ensure the signal can be stabilized, high quality, long-distance transmission and realized two-way return function. WS-SXG402 two-way trunk amplifiers are mainly used in all kinds of two-way CATV systems, satellite television systems, residential CCTV surveillance system, hotel audiovisual systems, as well as military units, schools and other educational audio-visual systems.


  • Feature
  • Parameter
  • Diagram

● High-quality diplex filter, split points optional.

● Forward amplifying circuit adopt two modules to enlarge. 

● Low-noise push-pull amplifier module, which make sure the noise indicator of equipment

● later stage uses power doubler module.

● Adjustable attenuator and equalizer in forward and reverse path,equipped with two balancing attenuation adjustment, construction easier.

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

● Two outputs, Changeable tap or splitter.

● High-reliability switching power supply.
