ZBL43C CATV Bi-Directional Amplifier

+SGS Approved +Passed ISO9001:2000 +Powerful R&D Strength +MOQ 1 Pcs +OEM Available

Description                                                   

ZBL43D high-performance amplifier can be applied to 550MHz, 750MHz or 862MHz CATV bi-directional transmission system to compensate the RF signal loss on the cable transmission network.

Features

1. Compact in size with full function

2. Chinese or PHILIPS push-pull module design with high performance

3. Total seal waterproof shell made of new-type aluminum alloy

4. Optional power supply mode: local power supply (220V)/central power supply (60V)

5. Mobile relay structure is applied to amplifier inner equalizer, attenuator, bi-directional filter and amplifying module, which guarantees a flexible and convenient operation
