Kachiwiri, SMD surface mount Circulator ili ndi magwiridwe antchito abwino odzipatula. Amatha kusiyanitsa bwino ma siginolo otumizira ndi kulandira, kupewa kusokoneza, komanso kusunga umphumphu wa ma siginolo. Kupambana kwa magwiridwe antchito odzipatula kumeneku kungatsimikizire kuti makinawo akugwira ntchito bwino ndikuchepetsa kusokoneza ma siginolo.
Kuphatikiza apo, SMD surface mount Circulator ilinso ndi kukhazikika kwabwino kwa kutentha. Amatha kugwira ntchito pa kutentha kwakukulu, nthawi zambiri kufika kutentha kuyambira -40 ° C mpaka +85 ° C, kapena kupitirira apo. Kukhazikika kwa kutentha kumeneku kumathandiza SMD surface mount Circulator kugwira ntchito moyenera m'malo osiyanasiyana.
Njira yopangira ma SMD surface mount Circulators imathandizanso kuti zikhale zosavuta kuziphatikiza ndikuziyika. Amatha kuyika mwachindunji zida zozungulira pa ma PCB kudzera muukadaulo wopangira, popanda kufunikira njira zachikhalidwe zoyika ma pini kapena soldering. Njira yopangira ma surface mount iyi sikuti imangowonjezera magwiridwe antchito, komanso imalola kuphatikiza kwakukulu, motero kusunga malo ndikupangitsa kuti kapangidwe ka makina kakhale kosavuta.
Kuphatikiza apo, ma SMD surface mount Circulators ali ndi ntchito zambiri mu makina olumikizirana a pafupipafupi komanso zida zama microwave. Angagwiritsidwe ntchito kupatula zizindikiro pakati pa ma amplifiers a RF ndi ma antenna, zomwe zimapangitsa kuti makina azigwira ntchito bwino komanso kukhazikika. Kuphatikiza apo, ma SMD surface mount Circulators angagwiritsidwenso ntchito muzipangizo zopanda zingwe, monga kulumikizana opanda zingwe, machitidwe a radar, ndi kulumikizana kwa satellite, kuti akwaniritse zosowa za kudzipatula kwa ma signal a pafupipafupi komanso kusweka.
Mwachidule, chipangizo choyimitsa pamwamba cha SMD ndi chipangizo chopepuka, chopepuka, komanso chosavuta kuyika chokhala ngati mphete chomwe chili ndi bandeji yozungulira, magwiridwe antchito abwino odzipatula, komanso kukhazikika kwa kutentha. Chili ndi ntchito zofunika kwambiri m'magawo monga machitidwe olumikizirana pafupipafupi, zida zama microwave, ndi zida zama wailesi. Ndi chitukuko chopitilira chaukadaulo, ma SMD surface mount Circulators adzachita gawo lofunikira m'magawo ambiri ndikuthandizira pakukula kwaukadaulo wamakono wolumikizirana.
Circulator ya RF Surface Mount Technology (RF SMT) ndi mtundu wapadera wa chipangizo cha RF chomwe chimagwiritsidwa ntchito kuwongolera ndikuwongolera kuyenda kwa chizindikiro mu machitidwe a RF. Mfundo yake yogwirira ntchito imachokera pa kuzungulira kwa Faraday ndi zochitika za magnetic resonance mu ma electromagnetics. Chinthu chachikulu cha chipangizochi ndikulola zizindikiro zomwe zili mbali inayake kudutsa pamene zikuletsa zizindikiro zomwe zili mbali ina.
Chozungulira cha RF SMT chimakhala ndi madoko atatu, omwe chilichonse chingagwiritsidwe ntchito ngati cholowetsa kapena chotulutsa. Chizindikiro chikalowa mu doko, chimalunjika ku doko lotsatira kenako chimatuluka kuchokera ku doko lachitatu. Njira yoyendera kwa chizindikirochi nthawi zambiri imakhala mozungulira wotchi kapena mozungulira wotchi. Ngati chizindikirocho chikuyesera kufalikira mwanjira yosayembekezereka, chozungulira chimatseka kapena kuyamwa chizindikirocho kuti chisasokoneze ziwalo zina za dongosolo kuchokera ku chizindikiro chobwerera.
Ubwino waukulu wa ma RF SMT circulators ndi miniaturization yawo komanso kuphatikizana kwakukulu. Chifukwa chogwiritsa ntchito ukadaulo woyika pamwamba, circulator iyi imatha kuyikidwa mwachindunji pa bolodi la circuit popanda kufunikira mawaya owonjezera olumikizira kapena zolumikizira. Izi sizimangochepetsa kuchuluka ndi kulemera kwa zida, komanso zimapangitsa kuti kukhazikitsa ndi kukonza kukhale kosavuta. Kuphatikiza apo, chifukwa cha kapangidwe kake kogwirizana kwambiri, ma RF SMT circulators nthawi zambiri amakhala ndi magwiridwe antchito abwino komanso odalirika.
Mu ntchito zothandiza, ma RF SMT circulators amachita gawo lofunika kwambiri m'ma RF system ambiri. Mwachitsanzo, mu radar system, imatha kuletsa ma reverse echo signals kuti asalowe mu transmitter, motero kuteteza transmitter kuti isawonongeke. Mu ma communication system, ingagwiritsidwe ntchito kupatula ma antenna otumiza ndi kulandira kuti aletse chizindikiro chotumizidwa kuti chisalowe mwachindunji mu receiver. Kuphatikiza apo, chifukwa cha miniaturization yake komanso kuphatikiza kwake kwakukulu, RF SMT circulator imagwiritsidwanso ntchito kwambiri m'magawo monga magalimoto amlengalenga opanda anthu komanso kulumikizana kwa satellite.
Komabe, kupanga ndi kupanga ma RF SMT circulators kumakumananso ndi mavuto ena. Choyamba, popeza mfundo yake yogwirira ntchito imaphatikizapo chiphunzitso chovuta cha ma electromagnetic, kupanga ndi kukonza circulator kumafuna chidziwitso chakuya chaukadaulo. Kachiwiri, chifukwa chogwiritsa ntchito ukadaulo woyika pamwamba, njira yopangira circulator imafuna zida zolondola kwambiri komanso kuwongolera bwino khalidwe. Pomaliza, popeza doko lililonse la circulator liyenera kufanana molondola ndi kuchuluka kwa chizindikiro chomwe chikukonzedwa, kuyesa ndikukonza zolakwika, circulator imafunanso zida ndi ukadaulo waukadaulo.
