Kachiwiri, SMD surface mount Circulator imakhala ndi ntchito yabwino yodzipatula.Amatha kulekanitsa bwino ma siginecha otumizira ndi kulandira, kupewa kusokoneza, ndikusunga kukhulupirika kwazizindikiro.Kupambana kwa ntchito yodzipatula iyi kungathe kuonetsetsa kuti dongosololi likuyenda bwino komanso kuchepetsa kusokoneza kwa zizindikiro.
Kuphatikiza apo, SMD surface mount Circulator imakhalanso ndi kutentha kwabwino kwambiri.Amatha kugwira ntchito pa kutentha kwakukulu, komwe kumafika kutentha koyambira -40 ° C mpaka +85 ° C, kapena kukulirapo.Kukhazikika kwa kutenthaku kumathandizira kuti SMD surface mount Circulator igwire ntchito modalirika m'malo osiyanasiyana.
Njira yoyikamo ya SMD surface mount Circulators imapangitsanso kuti ikhale yosavuta kuphatikiza ndikuyika.Atha kukhazikitsa mwachindunji zida zozungulira pa PCB kudzera muukadaulo wokwera, popanda kufunikira kwa kuyika kwa pini kapena njira zogulitsira.Njira yokhazikitsira pamwambayi sikuti imangowonjezera luso la kupanga, komanso imathandizira kuphatikiza kachulukidwe, potero kupulumutsa malo ndikusintha kamangidwe kadongosolo.
Kuphatikiza apo, SMD surface mount Circulators imakhala ndi ntchito zambiri pamakina olankhulirana othamanga kwambiri komanso zida za microwave.Atha kugwiritsidwa ntchito kupatula ma siginecha pakati pa ma amplifiers a RF ndi tinyanga, kuwongolera magwiridwe antchito ndi bata.Kuphatikiza apo, SMD surface mount Circulators ingagwiritsidwenso ntchito pazida zopanda zingwe, monga kulumikizana opanda zingwe, makina a radar, ndi kuyankhulana kwa satellite, kuti akwaniritse zofunikira pakudzipatula kwa ma frequency apamwamba komanso kuphatikizika.
Mwachidule, SMD surface mount Circulator ndi yaying'ono, yopepuka, komanso yosavuta kuyiyika ngati mphete yokhala ndi ma frequency band, magwiridwe antchito odzipatula, komanso kukhazikika kwa kutentha.Ali ndi ntchito zofunika m'magawo monga njira zoyankhulirana zothamanga kwambiri, zida za microwave, ndi zida zamawayilesi.Ndi chitukuko chosalekeza chaukadaulo, SMD surface mount Circulators idzagwira ntchito yofunika kwambiri m'magawo ambiri ndikuthandizira pakupanga ukadaulo wamakono wolumikizirana.
RF Surface Mount Technology (RF SMT) circulator ndi mtundu wapadera wa chipangizo cha RF chomwe chimagwiritsidwa ntchito kuwongolera ndi kuyendetsa kayendedwe ka ma siginecha mumakina a RF.Mfundo yake yogwirira ntchito imachokera ku Faraday rotation ndi maginito resonance phenomena mu electromagnetics.Chofunikira chachikulu cha chipangizochi ndikulola kuti ma sign amtundu wina adutse pomwe akutsekereza ma siginecha mbali ina.
RF SMT circulator ili ndi madoko atatu, omwe amatha kukhala ngati cholowetsa kapena chotulutsa.Chizindikiro chikalowa padoko, chimalunjikitsidwa ku doko lotsatira ndikutuluka padoko lachitatu.Mayendedwe a chizindikirochi nthawi zambiri amakhala motsata wotchi kapena mopingasa.Ngati chizindikirocho chikuyesera kufalikira m'njira yosayembekezereka, wozungulirayo adzatsekereza kapena kutenga chizindikirocho kuti asasokonezedwe ndi mbali zina za dongosolo kuchokera ku chizindikiro chobwerera.
Ubwino waukulu wa RF SMT circulators ndi miniaturization yawo ndi kuphatikiza kwakukulu.Chifukwa cha ntchito pamwamba phiri luso, circulator izi akhoza mwachindunji anaika pa bolodi dera popanda kufunikira mawaya zina kulumikiza kapena zolumikizira.Izi sizimangochepetsa kuchuluka kwake komanso kulemera kwa zida, komanso zimathandizira kukhazikitsa ndi kukonza.Kuphatikiza apo, chifukwa cha mapangidwe ake ophatikizika kwambiri, zozungulira za RF SMT nthawi zambiri zimakhala ndi magwiridwe antchito komanso odalirika.
Pakugwiritsa ntchito, zozungulira za RF SMT zimagwira ntchito yofunika kwambiri pamakina ambiri a RF.Mwachitsanzo, mu pulogalamu ya radar, imatha kuletsa ma sigino a reverse echo kulowa mu transmitter, potero kuteteza chotumizira kuti chisawonongeke.M'makina olankhulirana, angagwiritsidwe ntchito kupatula ma antennas otumizira ndi kulandira kuti aletse chizindikiro chopatsirana kuti chisalowe mwachindunji kwa wolandila.Kuphatikiza apo, chifukwa cha miniaturization yake komanso kuphatikiza kwakukulu, RF SMT circulator imagwiritsidwanso ntchito kwambiri m'magawo monga magalimoto osayendetsedwa ndi ndege komanso kulumikizana kwa satellite.
Komabe, kupanga ndi kupanga zozungulira za RF SMT zimakumananso ndi zovuta zina.Choyamba, popeza mfundo yake yogwira ntchito imakhudza chiphunzitso chovuta chamagetsi, kupanga ndi kukhathamiritsa kozungulira kumafuna chidziwitso chazamaluso.Kachiwiri, chifukwa chogwiritsa ntchito ukadaulo wapamtunda, kupanga makina ozungulira kumafunikira zida zolondola kwambiri komanso kuwongolera bwino kwambiri.Pomaliza, monga doko lililonse la circulator liyenera kufananiza molondola ma frequency azizindikiro omwe akukonzedwa, kuyesa ndi kuwongolera kozungulira kumafunanso zida zaukadaulo ndiukadaulo.
