1. High-quality diplex filter, split points optional.
2. Forward amplifying circuit adopt two modules to enlarge. Low-noise push-pull amplifier module, make sure the noise indicator of equipment; later stage uses power doubler module.
3. Adjustable attenuator and equalizer in forward and reverse path,equipped with two balancing attenuation adjustment, construction easier.
4. RF test port in reverse path (-20dB).
5. Two outputs, Changeable tap or splitter.
6. High-reliability switching power supply.
