MIC-8230D series ALC two-way trunk amplifier is specially designed for two-way HFC transmission network. It adopts low-noise amplifier module, ALC( automatic gain control and automatic slope control )circuit, interstage revision circuit.
Features
1. 862MHz bandwidth.
2. High performance, low noise, low distortion.
3. The design of two-output can replace the mode of distribution or subdivision conveniently.
4. The built-in modulated equalizer and attenuator can be tested easily and conveniently.
5. Plug-in (pre-reserved) reverse return module can open up the reverse return channels easily.
6. The die-cast aluminum housing, high-quality switching power supply and effective lightningproof measure.
