Xidhiidhiyaha sare ee awoodda SPNT RF
Nooca
● Awood sare oo SPNT ah oo dareemaha coaxial
Inta jeer ee shaqada: DC-12.4GHz/18GHz
● Xidhiidhiyaha RF: Nooca N/SC ee dheddigga
● Milicsi
Waxqabadka RF
Go'doon sare: ka weyn 80 dB at 6GHz, ka weyn 70dB at 12.4GHz;
VSWR hoose: in ka yar 1.3 at 6GHz, in ka yar 1.5 at 12.4GHz;
Ins.less hoose: in ka yar 0.3dB at 6GHz, in ka yar 0.5dB at 12.4GHz.
RF wuxuu tijaabiyaa xasilloonida iyo nolosha adeeg dheer
Gelida luminta waxay ku celisaa xasilloonida tijaabada: 0.02dB at 6GHz, 0.03dB at 12.4GHz;
Hubi in 2 milyan jeer wareegga nolosha (hal channel goobaabin 2 milyan jeer).
Mabda'a hawlgalka ee beddelka RF
1. Beddelka heerka oggolaanshaha RF wuxuu qaataa seddex terminal Cote - Tiknoolajiyada gaashaanka si loo baabi'iyo saameynta walxaha ku dheggan korantada ogaanshaha ee saameynta xakamaynta.Calaamadaha soo noqnoqda ee sarreeya ee ka soo baxa wareegga elektiroonigga ah waxaa si toos ah loogu diraa korantada ogaanshaha ee hal dhinac iyo galka ka hortagga adhesionka iyada oo loo marayo raacaha korantada RF ee dhinaca kale.Cabbirkeeda iyo wejigeeda waxay la mid yihiin calaamadda lagu daray usha baaritaanka.Marka alaabtu ay u hoggaansamaan baaritaanka, awood ayaa ka dhex abuurma gacanta gaashaanka iyo gidaarka biinka, markaa calaamadda soo noqnoqoshada badan ee lagu daray shaadhka difaaca ayaa buuxin doonta awoodda, si signalka soo noqnoqda sare ee baaritaanka uusan u qulqulin gidaarka weelka dhex mara lakabka xabagta.Marka tiro badan oo alaabta ku jirta weelka ay la soo xiriiraan baaritaanka, hadda ku jira baaritaanka wuxuu dhaafi doonaa aagga dheriga oo u qulquli doona gidaarka weelka, sidaas darteed soo saarista calaamadda joogitaanka alaabta.
2. Beddelka heerka oggolaanshaha RF wuxuu adeegsadaa tignoolajiyada soo noqnoqda sare si uu u dhaliyo calaamad yar oo RF ah oo ku taal baaritaanka wareegga elektaroonigga ah, baaritaankuna wuxuu u shaqeeyaa sidii cunsur dareen ah oo dib loogu celinayo isbeddellada calaamadaha ay sababto joogteynta dielectric ee heerka wareegga elektarooniga ah;Sababtoo ah isbeddelladan waxaa ka mid ah isbeddelada awoodda iyo haynta, wareegga elektaroonigga ah wuxuu ka shaqeeyaa falcelinta (calaamadaha isbeddellada dhammaystiran ee falcelinta awoodda iyo ka hortagga) calaamadda.
3. Isbeddelka falcelinta waxay sababtaa isbeddelka wejiga ee calaamadda soo noqnoqoshada sare ee tiirka.Sidaa darteed, farqiga wejiga ee u dhexeeya calaamadda soo noqnoqda sare ee tiirka iyo calaamadda tixraaca ee wareegga elektaroonigga ah ayaa sidoo kale isbeddelaya.Ka dib marka isbeddelka la habeeyo, wareegga wax soo saarka wadista ayaa soo diraya signalka alaarmiga si loo ogaado haddii ay jiraan wax ku jira silo.
