Kev piav qhia txog khoom
Cov Lus Qhia Txog Khoom
Peb lub tuam txhab qhov tseeb tshaj plaws plaub-output CATV network optical receiver SR814ST, lub pre-amplifier siv tag nrho GaAs MMIC, thiab lub post-amplifier siv GaAs modules. Nrog rau kev tsim hluav taws xob zoo tshaj plaws thiab 10 xyoo ntawm kev tsim qauv kev tshaj lij, lub cuab yeej tau ua tiav cov cim qhia kev ua tau zoo heev. Tsis tas li ntawd, kev tswj hwm microprocessor thiab cov zaub digital parameter ua rau kev debugging engineering yooj yim heev. Nws yog cov khoom siv tseem ceeb tsim nyog rau kev tsim CATV network.
Cov yam ntxwv ntawm kev ua tau zoo
Peb lub CATV network optical receiver SR814ST adopts high-responsive PIN photoelectric conversion tube, optimizes circuit tsim thiab SMT txheej txheem ntau lawm, thiab paub tseeb tias du thiab zoo kis tau cov teeb liab photoelectric.
Cov chips RF attenuation tshwj xeeb muab cov linear attenuation meej, thaum peb cov khoom siv GaAs amplifier muab qhov nce siab thiab qis distortion. Lub kaw lus yog tswj los ntawm ib lub microcomputer ib leeg-chip (SCM), nrog cov qauv LCD zaub, kev ua haujlwm yooj yim thiab intuitive, thiab kev ua haujlwm ruaj khov.
Lub kaw lus AGC ua kom ntseeg tau tias qib tso zis tseem nyob ruaj khov ntawm qhov ntau ntawm lub zog kho qhov muag ntawm -9 txog +2 dBm nrog kev cuam tshuam tsawg kawg los ntawm CTB thiab CSO. Lub kaw lus kuj suav nrog lub interface sib txuas lus cov ntaub ntawv tshwj tseg, uas tuaj yeem txuas nrog hom II network management responder thiab txuas nrog lub network management system. Txhua yam kev ntsuas raug ntsuas raws li GY / T 194-2003, nyob rau hauv cov xwm txheej xeem txheem.
Tsis tau paub meej tias yog dab tsi?
