Product Description
Product Summary
Peb lub tuam txhab qhov tseeb high-end plaub-tso tawm CATV network optical receiver SR814ST, pre-amplifier siv tag nrho GaAs MMIC, thiab tom qab-amplifier siv GaAs modules. Nrog optimized Circuit Court tsim thiab 10 xyoo ntawm kev tsim kev paub, lub cuab yeej tau ua tiav cov ntsuas kev ua tau zoo. Tsis tas li ntawd, microprocessor tswj thiab digital parameter zaub ua rau engineering debugging yooj yim heev. Nws yog cov cuab yeej tseem ceeb tsim nyog rau kev tsim CATV network.
Cov yam ntxwv ua haujlwm
Peb cov CATV siab heev network optical receiver SR814ST txais cov lus teb tus PIN photoelectric hloov dua siab tshiab raj, optimizes Circuit Court tsim thiab SMT txheej txheem ntau lawm, thiab realizes smooth thiab npaum kis tau tus mob ntawm photoelectric signals.
Dedicated RF attenuation chips muab qhov tseeb linear attenuation, thaum peb GaAs amplifier pab kiag li lawm muab siab nce thiab tsawg distortion. Lub kaw lus tau tswj hwm los ntawm ib qho-chip microcomputer (SCM), nrog rau LCD zaub tsis, kev ua haujlwm yooj yim thiab nkag siab, thiab kev ua haujlwm ruaj khov.
AGC system ua kom ntseeg tau tias cov zis theem tseem nyob tas li ntawm qhov muag qhov muag ntawm -9 txog +2 dBm nrog kev cuam tshuam tsawg heev los ntawm CTB thiab CSO. Lub kaw lus tseem suav nrog cov ntaub ntawv sib txuas lus tshwj xeeb, uas tuaj yeem txuas nrog hom II network tswj cov lus teb thiab txuas nrog kev tswj hwm network.Txhua qhov kev ntsuas tsis raug ntsuas raws li GY / T 194-2003, raws li cov qauv ntsuas
