WA12-A bi-directional amplifier, which supports DOCSIS 3.1 and different frequency splitting, is suitable for 1.22G HFC bidirectional network. Advanced GaAs technology effectively improves line distortion and noise figure for great product performance improvement. Specifically designed for both indoor and outdoor rack-mounted applications with 15PSI waterproof and 6KV surge withstand on the F connector. WA12-A has reasonable circuit, scientific structure and excellent performance index.
* Wide bandwidth, maximum frequency is up to 1.22G.
* Full GaAs MMIC amplifying components.
* 3dB noise figure.
* LED power indicator.
* Support remote and local DC power supply.
* DC15V power adapter.
* 15PSI for a minute water withstand (all F ports).
* Low power consumption design.
* Aluminum die-cast housing.
