Products Description 

ERB802AH optical receiver is our new development products that especially used in CATV network. The pre-amp adopts GaAs MMIC amplify module and the post-amp adopts GaAs power doubler amplify module (the series have two kinds of model, one is M model that the RF attenuation and equilibrium design adopts successive adjustability, the other is MF model which adopts unadjustable insert, or as per customer, adopts other module).With optimization design and plentiful technical experience that made this equipment with high performance specification. It is a ideal model for CATV network.

 

Performance Characteristics

High responsible, With PIN photoelectric converter;

High precision, with 10 cascade LED display the optical power;

Optimization and typical circuit design, the pre adopts SMT process and the post adopts module amplify that made the photoelectric signal transmission fluency;

Convenient debugging with adjustable RF ATT and EQ;

Power doubler output , high gain and low distortion;

With AGC, when the input power range is -7 ~ +2dBm, the output level, CTB and CSO are keep constantly;
