CATV Amplifier feature:
1.1003MHz bandwidth design.
2. Forward path: The pre-stage adopts GaAs MMIC, output stage adopts the newest imported
High index power doubly module, achieve high output level, low distortion and high SNR.
3. Plug-in duplex filter, EQ, ATT.
4. The equipment can long time continuous work steadily under outdoor bad environmental condition.
