CATV RF Two Port Outdoor Bidirectional Amplifier

Product Description

CATV RF Two Port Outdoor Bidirectional Amplifier
Product Description
WA1200CEAM series outdoor modular bidirectional trunk amplifier is a
new high gain amplifier. Adopt mature and optimized circuit design, scientific
and rational internal process, high quality materials, to ensure the stable
gain and low distortion.
Performance Characteristics
1. Forward path adopts imported low noise amplify module or GaAs push-
pull module.
2. Return path adopts the newest high index imported reverse dedicated amplify
module.
3. Convenient to debug because of the plug- in duplex filter, fixed equalizer and
attenuator (EQ and ATT both adopt fixed attenuator to adjust the equilibrium
and attenuation), plug-in output tap or splitter, and the scientific and reasonable
on-line detection ports.
4. The output level mode is AGC or MGC optional, it is more convenient.
5. Aluminum waterproof housing, high reliability switching power supply and strict
lightning protection system.
6. The structure adopts embedded modular design, easy to maintain, replace and
debug.
