Amplifier
FEATURES AND SPECIFICATION
- High quality amplification module system at 54/87- 860MHz
- bandwidth for forward direction and 5-40/65MHz for reverse path.
- For two way amplifier: Plug-in duplex filters are capable of two
- way Transmission; Reverse bandwidth 5-40/ 5-65 optional.
- Two outputs which can plug-in direction coupler to change output value.
- Both the input and output have testing points (-20dB).
- Input, outputs are all equipped with arrestors that
- reduce mechanical breakdowns from sudden electrical surges.
- Trunk line amplifiers allow forward, backward power supply.
- Uses high efficiency transformer / switch power.
