Khuếch Đại Trunk 1GHz MTA-1G36A
- Two-way amplifier design with plug-in GaAs FET / HFET Hybrid Amplifier Modules for both Forward and Reverse path and High Performance Diplex Filters, with high output power, low inter-modulation distortions and low power consumption, suitable for using as trunk and distribution amplifier in medium to large HFC networks.
- Adjustable gain and slope by on-board plug-in variable attenuator or fixed attenuator (Pad) and equalizer modules for both forward and reverse path.
- Test points (-20 dB) at forward path and reverse path, input and output
- 60V AC line powered with high performance switch-mode power supply
- 10A AC feed through to any input and output ports, with 10 A plug-in fuses and replaceable lightning protectors for all ports and power supply module.
- Die-cast aluminum housing meets IP67 degree for dust and water protection, and environmental coating provides excellent corrosion resistance.
- The housing with plug-in shielded RF platform, easy to repair and upgrade on field
