SA831R CATV Outdoor Trunk Amplifier with AGC
-Product description
Field Bidirectional AGC Trunk Amplifier is a new high gain amplifier. Adopt mature and optimized circuit design, scientific and rational internal process, high quality materials, and builtin high performance AGC control circuit to ensure the stable gain and low distortion. It's the best choice for large and medium-sized bidirectional CATV transmission network.
-Product feature
Use Micro-tube pre-amplify and low noise Philips power doubler module(BGD814).
EQ, ATT have fixed or adjustable
Output splitter(FZ110) or coupler(FP204) can plug change to make engineering debug more agile
More powerful, less consumption
The forward preceding stage adopts the newest high index imported low noise push pull amplifier modules or GaAs push pull modules, output stage adopts high index imported power-double amplifier modules or GaAs amplifier modules. The output level is high and the nonlinear index is good. The backward adopts the newest high index imported return dedicated amplifier modules. The distortion is low and signal to noise ratio is high.
It is more convenient to debug, because of plug-in duplex filter, plug-in fixed (or adjustable) equalizer and attenuator, plug-in output splitter and scientific and rational on-line detection ports.
Built-in optimized high performance AGC control circuit, make the control more accurate and the link signal working more stable. The equipment can work steadily outdoor under bad environmental condition, because of waterproof aluminum case, high reliability switching power supply and lightning protection system.
