CATV Amplifier feature:
1.CATV Amplifier Forward path adapts import PHILPS or NEC low noise push-pull amplify module or GaAs push-pull module, the output adapts two independent PHILPS or NEC double power amplify module or GaAs amplify module
2.CATV Amplifier reverse path adapts PHILIPS return amplifiy module, low distortion and high SNR.
3.Plug-in diplexer, plug-in fixed (or adjustable) EQ, fixed (or adjustable) ATT, plug-in output tap and with online testing port
4.Built-in optimization high performance AGC control circuit
5.Waterproof aluminum housing, high reliability switch power, strictly anti-thunder system.
