Marka labaad, SMD dusha sare ee Circulator-ka wuxuu leeyahay waxqabad go'doon oo wanaagsan.Waxay si wax ku ool ah u go'doomin karaan gudbinta iyo helitaanka calaamadaha, ka hortagga faragelinta, oo ay ilaaliyaan daacadnimada calaamadaha.Sarreynta waxqabadka go'doominta waxay xaqiijin kartaa hawlgalka hufan ee nidaamka waxayna yareyn kartaa faragelinta calaamadaha.
Intaa waxaa dheer, SMD dusha Buur Circulator sidoo kale waxay leedahay xasillooni heerkul aad u fiican.Waxay ku shaqayn karaan heerkul aad u ballaadhan, caadi ahaan waxay gaadhaan heerkul u dhexeeya -40 ° C ilaa +85 ° C, ama xataa ka sii ballaadhan.Xasiloonida heerkulku waxa uu u sahlayaa SMD Dusha Buur Circulator in uu si la isku hallayn karo uga shaqeeyo degaano kala duwan.
Habka baakadaha ee SMD dusha sare ee Circulators waxay sidoo kale ka dhigtaa mid fudud in la isku daro oo la rakibo.Waxay si toos ah ugu rakibi karaan aaladaha wareegtada PCB-yada iyaga oo adeegsanaya tignoolajiyada kor u kaca, iyada oo aan loo baahnayn gelinta biin dhaqameedka ama hababka alxanka.Habka baakadaha dusha sare ee dusha sare ma aha oo kaliya hagaajinta waxtarka wax soo saarka, laakiin sidoo kale wuxuu awood u siinayaa isdhexgalka cufnaanta sare, taas oo badbaadinaysa booska iyo fududaynta naqshadaynta nidaamka.
Intaa waxaa dheer, SMD dusha sare ee Circulators waxay leeyihiin codsiyo ballaaran oo ku saabsan hababka isgaarsiinta ee soo noqnoqda iyo qalabka microwave.Waxaa loo isticmaali karaa in lagu go'doomiyo calaamadaha u dhexeeya cod-weyneyaasha RF iyo anteenooyinka, hagaajinta waxqabadka nidaamka iyo xasilloonida.Intaa waxaa dheer, SMD dusha sare ee Circulators sidoo kale waxaa loo isticmaali karaa aaladaha wireless-ka, sida isgaarsiinta wireless-ka, nidaamyada radar, iyo isgaarsiinta satellite-ka, si loo daboolo baahiyaha go'doominta calaamadaha sare ee soo noqnoqda iyo kala-goynta.
Marka la soo koobo, SMD dusha sare ee Circulator waa mid cufan, khafiif ah, oo sahlan in lagu rakibo qalab giraan u samaysan oo leh daboolka xad-dhaafka ah ee soo noqnoqda, go'doominta wanaagsan, iyo xasilloonida heerkulka.Waxay leeyihiin codsiyo muhiim ah oo ku saabsan dhinacyada sida hababka isgaarsiinta ee soo noqnoqda, qalabka microwave, iyo qalabka raadiyaha.Horumarka joogtada ah ee tignoolajiyada, SMD dusha sare ee Circulators waxay door muhiim ah ka ciyaari doontaa dhinacyo badan waxayna gacan ka geysan doontaa horumarinta tignoolajiyada isgaarsiinta casriga ah.
Wareegtada RF Surface Mount Technology (RF SMT) waa nooc gaar ah oo ka mid ah aaladda RF ee loo isticmaalo in lagu xakameeyo laguna maareeyo socodka signallada ee nidaamyada RF.Mabda'a shaqadeedu waxay ku salaysan tahay wareegtada Faraday iyo ifafaalaha resonance magnetka ee korantada.Muuqaalka ugu muhiimsan ee qalabkani waa inuu u oggolaado calaamadaha jihada gaarka ah inay dhex maraan iyadoo la xannibayo calaamadaha jihada ka soo horjeeda.
Wareegtada RF SMT waxay ka kooban tahay saddex dekedood, kuwaas oo mid kastaa u adeegi karo sidii wax-soo-saar ama wax-soo-saar.Marka signalku soo galo dekedda, waxa loo jiheeyaa dekedda ku xigta ka dibna ka baxa dekedda saddexaad.Jihada uu u socdo signalkani waxa uu badiyaa u jeedaa saacada ama saacada ka soo horjeeda.Haddii calaamaduhu isku dayo inuu ku faafo jihada lama filaanka ah, wareegga ayaa xannibi doona ama nuugi doona calaamadda si looga fogaado faragelinta qaybaha kale ee nidaamka ee calaamadda gadaal.
Faa'iidooyinka ugu muhiimsan ee wareegayaasha RF SMT waa yareyntooda iyo isdhexgalka sare.Sababtoo ah isticmaalka tignoolajiyada korka sare ee dusha sare, wareegtada ayaa si toos ah loogu dhejin karaa guddiga wareegga iyada oo aan loo baahnayn fiilooyin dheeraad ah oo isku xira ama xirayaasha.Tani kaliya ma yarayso mugga iyo miisaanka qalabka, laakiin sidoo kale waxay fududeyneysaa habka rakibidda iyo dayactirka.Intaa waxaa dheer, iyadoo ay ugu wacan tahay naqshadeeda aadka isku dhafan, wareegtada RF SMT waxay sida caadiga ah leeyihiin waxqabad wanaagsan iyo isku hallayn.
Codsiyada la taaban karo, wareegtada RF SMT waxay door muhiim ah ka ciyaaraan nidaamyo badan oo RF ah.Tusaale ahaan, nidaamka raadaarka, waxa uu ka hortagi karaa calaamadaha dhawaaqa roga ee soo noqnoqda in ay galaan gudbiyaha, si ay uga ilaaliso gudbiyaha dhaawaca.Nidaamyada isgaarsiinta, waxaa loo isticmaali karaa in lagu go'doomiyo gudbinta iyo helitaanka anteenooyinka si looga hortago in signalka la gudbiyo uu si toos ah u galo soo-dhowrka.Intaa waxaa dheer, iyada oo ay ugu wacan tahay yaraynta iyo is-dhexgalka sare, wareegga RF SMT ayaa sidoo kale si weyn loogu isticmaalaa meelaha sida baabuurta aan duuliyaha lahayn iyo isgaarsiinta satellite-ka.
Si kastaba ha ahaatee, naqshadaynta iyo soo saarista wareegayaasha RF SMT ayaa sidoo kale wajahaya caqabado.Marka hore, maadaama mabda'eeda shaqadu ay ku lug leedahay aragtida korantada ee adag, naqshadaynta iyo tayaynta wareegtada waxay u baahan tahay aqoon xirfadeed qoto dheer.Marka labaad, iyadoo ay ugu wacan tahay isticmaalka tignoolajiyada korka sare ee dusha sare, habka wax soo saarka ee wareegga wuxuu u baahan yahay qalab sax ah oo sarreeya iyo xakamaynta tayada adag.Ugu dambayntii, maadaama deked kasta oo ka mid ah wareegga wareegga ay u baahan tahay inay si sax ah u wajahdo inta jeer ee signallada la farsamaynayo, tijaabinta iyo cilladaynta wareegga waxay sidoo kale u baahan tahay qalab xirfadeed iyo teknooloji.
