OPCA-8238CEAM Outdoor Bi-directional AGC Trunk Amplifier
   Content
Description
OPCA-8238CEAM Outdoor Bi-directional AGC Trunk Amplifier is a new developed amplifier. It is adapts optimization circuit design, with scientific and reasonable internal process and very good material and also built-in high performance AGC control circuit, so as to ensure the stability gain and low distortion. It is the first choice of large and medium-sized two-way CATV transmission network equipment.
 
Product feature
1. Forward path adapts import PHILPS or NEC low noise push-pull amplify module or GaAs push-pull module, the output adapts PHILPS or NEC double power amplify module or GaAs amplify module that made to high output level and excellent nonlinear index. Return path adapts especially PHILIPS reverse amplify module that made to low distortion and high SNR.
2. Plug-in diplexer, plug-in fixed (or adjustable) EQ, fixed (or adjustable) ATT, plug-in output tap and with online testing port that made to more convenience project adjusting.
3. Built-in optimization high performance AGC control circuit to ensure the circuit signal processing stability.
4. Waterproof aluminum housing, high reliability switch power, strictly anti-thunder system that make sure the equipment can long time stability working under field harsh environment.
