RF iyo furayaasha mikrowave waxay soo diri karaan calaamadaha si hufan jidka gudbinta.Shaqooyinka furayaashan waxaa lagu tilmaami karaa afar cabbir oo koronto oo aasaasi ah.In kasta oo dhowr qaybood ay la xiriiraan waxqabadka RF iyo furayaasha mikrowave, afartan cabbir ee soo socda ayaa loo arkaa inay yihiin kuwo muhiim ah xiriirkooda xooggan awgeed:
Karantiil
Go'doomintu waa hoos u dhaca u dhexeeya wax-gelinta iyo soo-saarka wareegga.Waa cabirka waxtarka goynta ee dareemaha.
Luminta galitaanka
Gelida luminta (sidoo kale loo yaqaan luminta gudbinta) waa wadarta tamarta lumay marka daaruhu ku jiro gobolka.Luminta gelinta ayaa ah halbeegga ugu muhiimsan ee naqshadeeyayaasha sababtoo ah waxay si toos ah u horseedi kartaa kororka tirada qaylada nidaamka.
Waqtiga beddelka
Wakhtiga beddelka waxa loola jeedaa wakhtiga loo baahan yahay in laga beddelo gobolka "on" loona beddelo "off" gobolka iyo "off" gobolka oo loo beddelo "on" gobolka.Waqtigaan wuxuu gaari karaa mikrose seconds ee korontada sare iyo nanoseconds ee xawaaraha hoose ee xawaaraha sare.Qeexida ugu caansan ee wakhtiga beddelka waa wakhtiga looga baahan yahay korantada kontoroolka wax-gelinta oo gaadhay 50% ilaa awoodda wax-soo-saarka RF ee u dambaysa oo gaadhaysa 90%.
Awoodda farsamaynta awoodda
Intaa waxaa dheer, awoodda maaraynta korantada waxaa lagu qeexaa inay tahay awoodda wax-is-gelinta ee ugu badan ee RF ee beddelka uu u adkeysan karo iyada oo aysan jirin wax koronto ah oo joogto ah.
Bedelka RF ee adag
Dareemaha RF ee adag waxaa loo qaybin karaa nooc aan milicsi lahayn iyo nooca milicsiga.Dareeraha aan milicsiga lahayn waxaa lagu qalabeeyay iska caabin isbarbar dhig oo ah 50 ohm ee deked kasta oo wax soo saar ah si loo gaaro saamiga mawjadda taagan ee danab hoose (VSWR) labadaba gudaha iyo dibaddaba.Terminal resistor-ka ku dheggan dekedda wax-soo-saarka ayaa nuugi kara tamarta calaamadda dhacdada, halka dekedda aan lahayn iska-caabiyaha ku habboon ee terminal-ku ay muujin doonto calaamadda.Marka ay tahay in signalka gelinta lagu faafiyo furaha, dekedda furan ee kore waa laga gooyaa iska caabiyaha isbarbar-dhigga ee terminalka, sidaas darteed u oggolaanaysa in tamarta calaamaduhu si buuxda uga faafto furaha.Dareemaha nuugista ayaa ku habboon codsiyada halka loo baahan yahay in la yareeyo milicsiga dhawaaqa isha RF.
Taa beddelkeeda, furayaasha milicsiga kuma xidhna iska caabiyeyaasha terminaalka si loo yareeyo gelinta gelinta dekedaha furan.Dareemaha milicsiga waxay ku habboon yihiin codsiyada aan dareensanayn saamiga sare ee hirarka taagan ee ka baxsan dekedda.Intaa waxaa dheer, beddelka milicsiga, isbarbardhigga impedance waxaa xaqiiqsaday qaybo kale oo aan ahayn dekedda.
Muuqaal kale oo xusid mudan oo ka mid ah furayaasha gobolka adag ayaa ah wareegyadooda darawalnimada.Noocyo ka mid ah furayaasha gobolka adag ayaa lagu dhex daray darawallada korantada kontoroolka gelinta.Xaaladda macquulka ah ee korantada kontoroolka korantada ee darawaladani waxay gaari karaan hawlo kontorool oo gaar ah - bixinta hadda lagama maarmaanka ah si loo hubiyo in diodeku uu heli karo korantada eexda ama hore u socota.
Qalabka korantada iyo kuwa adag ee RF-ga ayaa laga samayn karaa noocyo kala duwan oo badeecooyin leh astaamo baakado kala duwan iyo noocyo isku xidha - inta badan alaabada beddelka coaxial ee leh soo noqnoqoshada hawlgalka ilaa 26GHz waxay isticmaalaan isku xidhayaasha SMA;Ilaa 40GHz, 2.92mm ama xiriiriyaha nooca K waa in la isticmaalaa;Ilaa 50GHz, isticmaal isku xirka 2.4mm;Ilaa 65GHz isticmaal xirayaasha 1.85mm.
