Khuếch Đại Trunk 870MHz LEA-8734
- Two-way amplifier design with plug-in GaAs FET Hybrid Amplifier Modules and High Performance Diplex Filters, with high output level power and low power consumption, suitable for using as trunk and distribution amplifier in medium to large HFC networks.
- Adjustable gain, plug-in fixed slop / equalizer for forward and return path.
- Plug-in return hybrid amplifier module.
- Test points (-20dB) at forward path and return path, input and output
- 60VAC line powered with high performance switchmode power supply
- 15A AC feed through to any input and output ports, with 15A plug-in fuses and replaceable lightning protectors for each ports.
- Die-cast aluminium housing meets IP67 degree for dust and water protection, and environmental coating provides excellent corrosion resistance
