Umuyoboro wa Coaxial
Umuyoboro wa Coaxial ni igikoresho cyoroshye gikoreshwa muri RF na microwave yumurongo wa bande, akenshi bikoreshwa mukwigunga, kugenzura icyerekezo, hamwe no kohereza ibimenyetso.Ifite ibiranga igihombo gito cyo kwinjiza, kwigunga cyane, hamwe na bande yagutse, kandi ikoreshwa cyane mubitumanaho, radar, antenne nubundi buryo.
Imiterere shingiro yumuzunguruko wa coaxial igizwe numuyoboro wa coaxial, cavit, umuyoboro wimbere, rukuruzi ya ferrite izunguruka, nibikoresho bya magneti.

Tera mumuzenguruko
Ikwirakwizwa rya RF ni ubwoko bwibikoresho bya RF bifasha kwanduza icyerekezo kimwe cyogukwirakwiza amashanyarazi, cyane cyane muri radar na microwave sisitemu yo gutumanaho imiyoboro myinshi.Akato kashyizwemo gahujwe nibikoresho byabikoresho binyuze mumuzunguruko.
Ikwirakwizwa rya RF ni icyuma cya microwave yicyambu 3 gikoreshwa mugucunga icyerekezo no guhererekanya ibimenyetso mumuzunguruko wa RF.RF yashyizwemo uruziga ntiruyobora, rutuma ingufu zoherezwa ku isaha kuva kuri buri cyambu kugera ku cyambu gikurikira.Izi nzitizi za RF zifite impamyabumenyi yo kwigunga igera kuri 20dB.

Umuyoboro mugari
Umuyoboro mugari ni ikintu cyingenzi muri sisitemu yitumanaho ya RF, utanga urukurikirane rwibyiza bituma bikwiranye na porogaramu zitandukanye.Izi nzitizi zitanga umurongo mugari, zitanga imikorere inoze mugihe kinini.Nubushobozi bwabo bwo gutandukanya ibimenyetso, barashobora gukumira kwivanga mubimenyetso bya bande no gukomeza ubusugire bwibimenyetso bya bande.
Kimwe mu byiza byingenzi byogukwirakwiza umurongo mugari ni byiza cyane byo kwigunga.Muri icyo gihe, ibyo bikoresho bimeze nk'impeta bifite icyambu cyiza gihagaze neza, kugabanya ibimenyetso byerekanwe no gukomeza kohereza ibimenyetso bihamye.

Inzira ebyiri
Imirongo ibiri ihuza umuzenguruko ni igikoresho cyoroshye gikoreshwa muri microwave na milimetero yumurongo wumurongo.Irashobora kugabanwa mubice bibiri bihuza coaxial circulators hamwe na joriji ebyiri zashyizwemo uruziga.Irashobora kandi kugabanywamo ibice bine byuzuzanya byuzuzanya hamwe nibyuma bitatu byuzuzanya bishingiye ku mubare wibyambu.Igizwe no guhuza ibice bibiri byumwaka.Gutakaza kwinjiza no kwigunga mubisanzwe bikubye kabiri ibyumuzenguruko umwe.Niba urwego rwo kwigunga rwumuzenguruko umwe ari 20dB, urwego rwo kwigunga rwikubye kabiri Uruziga rushobora kugera kuri 40dB.Ariko, ntamahinduka menshi mubyambu bihagaze.
Guhuza ibicuruzwa bya Coaxial mubusanzwe ni SMA, N, 2.92, L29, cyangwa DIN.Ibicuruzwa byashyizwemo bihujwe hakoreshejwe insinga.

Umuzenguruko wa SMD
Ubuso bwa SMD buzenguruka ni ubwoko bwibikoresho bimeze nkimpeta ikoreshwa mugupakira no kuyishyira kuri PCB (ikibaho cyumuzingo cyacapwe).Zikoreshwa cyane muri sisitemu yitumanaho, ibikoresho bya microwave, ibikoresho bya radio, nibindi bice.Ubuso bwa SMD hejuru yumuzenguruko bufite ibiranga kuba byoroshye, byoroheje, kandi byoroshye kwishyiriraho, bigatuma bikwiranye nubucucike bukabije bwimikorere yumuzunguruko.Ibikurikira bizatanga ibisobanuro birambuye kubiranga nibisabwa bya SMD hejuru yimisozi.
Ubwa mbere, SMD yubuso bwa Mount Circulator ifite intera nini yubushobozi bwo gukwirakwiza imirongo.Mubisanzwe bitwikiriye umurongo mugari, nka 400MHz-18GHz, kugirango byuzuze ibisabwa bya porogaramu zitandukanye.Ubu buryo bwagutse bwo gukwirakwiza ubushobozi butuma SMD igaragara hejuru yumuzunguruko gukora neza muburyo bwinshi bwo gusaba.

Microstrip
Microstrip Circulator nigikoresho gikoreshwa na RF microwave ikoreshwa mugukwirakwiza ibimenyetso no kwigunga mumuzunguruko.Ikoresha tekinoroji ya firime yoroheje kugirango ikore uruziga hejuru ya ferrite izunguruka, hanyuma ikongeramo umurima wa magneti kugirango ubigereho.Kwishyiriraho ibikoresho bya microstrip yumwaka mubisanzwe bifata uburyo bwo kugurisha intoki cyangwa insinga za zahabu zihuza imirongo yumuringa.
Imiterere ya microstrip izenguruka iroroshye cyane, ugereranije na coaxial kandi yashyizwemo.Itandukaniro rigaragara cyane ni uko nta cavit ihari, kandi umuyobozi wa microstrip Circulator ikorwa hifashishijwe uburyo bworoshye bwa firime (vacuum sputtering) kugirango ikore igishushanyo mbonera kuri ferrite.Nyuma ya electroplating, kiyobora yakozwe ifatanye na rotate ferrite substrate.Ongeraho urwego rwokwirinda hejuru yishusho, hanyuma ukosore umurima wa rukuruzi.Hamwe nuburyo bworoshye, umuzenguruko wa microstrip wahimbwe.

Umuyoboro wa Waveguide
Waveguide Circulator nigikoresho cyoroshye gikoreshwa muri RF na microwave imirongo yumurongo kugirango ugere kumurongo umwe no gutandukanya ibimenyetso.Ifite ibiranga igihombo gito cyo kwinjiza, kwigunga cyane, hamwe na Broadband, kandi ikoreshwa cyane mubitumanaho, radar, antenne nubundi buryo.
Imiterere shingiro yumuzunguruko urimo imirongo yohereza imirongo hamwe nibikoresho bya magneti.Umuyoboro wohereza umurongo ni umuyoboro w'icyuma unyuzwamo ibimenyetso.Ibikoresho bya magnetique mubisanzwe nibikoresho bya ferrite bishyirwa ahantu runaka mumirongo yohereza imirongo kugirango bigere ku bwigunge.
