SEM8602R Optical receiver is our new high-class products. The pre-amplifier adopts GaAs MMIC meanwhile post-amplifier adopts ACA series with SMD GaAs from USA, the optimization circuit design and with 10 years design experience that match to high performance index. The microprocessor control working status meanwhile LED digital display parameter that makes more convenience operation and becoming main products in CATV network.
Performance Characteristics
With PIN Photoelectric Converter and High Response.
Optimization circuit design, SMT process production, optimization signal path, fluency photoelectric signal transmission.
With specialized RF attenuate IC, Good linear of RF attenuation and equality and High accuracy.
GaAs amplify, power double output, high gain and low distortion.
Microprocessor control working status, LED shows all parameters, convenience operation and high stability.
Optimization AGC performance, when the input power range is -8~+2dBm, the output lever, CTB and CSO keep constantly.
