Bi-directional CATV Trunk Amplifier HCA-8606

1. Bi-directional Trunk amplifier 2. Excellent CTB & CSO 3. Flexible in network application 4. For CATV 5. High output level Product features

1. Bi-directional CATV Trunk amplifier adopting high linearity RF amplifier module as output-grade.

2. Excellent CTB and CSO at high output level.

3. Aluminum-cast housing, excellent performance in waterproof and heat-dissipation.

4. Has -20 dB test point at input or output line and be easy for adjustment at spot.

5. Separated reverse channel, adjustable reverse attenuation.

6. Has plug-in ATT and EQ at forward input line , reverse output line and among modules.

7. Modularized design for components, and be easy to maintain or upgrade.

8. The high quality switch PS can provide with +24V 1.5A current. The output range of 35~75VAC ensures the amplifier to work safely and reliably.

9. Adopt GaAS MMIC integrated circuit as its input grade and has low noise index.

10. For its Aluminum-cast housing with special waterproof and hanging design, it can be hung in the field with steel cable, and also can be installed in the building.

11. Be very flexible in network application.
