Coaxial switch ni pasiporo ya elegitoroniki ikoreshwa muguhindura ibimenyetso bya RF kuva kumuyoboro ujya mubindi.Ihinduranya rikoreshwa cyane mubihe byerekana ibimenyetso bisaba inshuro nyinshi, imbaraga nyinshi hamwe nubushobozi buke bwa RF.Irakoreshwa kandi muri sisitemu yikizamini cya RF, nka antene, itumanaho rya satelite, itumanaho, sitasiyo fatizo, indege, cyangwa izindi porogaramu zikeneye guhindura ibimenyetso bya RF kuva kuruhande rumwe.
Hindura icyambu
Iyo tuvuze kubijyanye na coaxial switch, dukunze kuvuga nPmT, ni ukuvuga, n pole m guta, aho n numubare winjira ibyambu na m numubare wibisohoka.Kurugero, RF ihindura hamwe icyambu kimwe cyinjiza nibisohoka bibiri byitwa SPDT / 1P2T.Niba RF switch ifite ibyinjijwe hamwe nibisohoka 14, dukeneye guhitamo RF switch ya SP14T.
Hindura ibipimo nibiranga
Niba ikimenyetso gikeneye guhindurwa hagati ya antenne ebyiri zirangira, dushobora guhita tumenya guhitamo SPDT.Nubwo ingano yo guhitamo yagabanutse kuri SPDT, turacyakeneye guhangana nibintu byinshi bisanzwe bitangwa nababikora.Tugomba gusoma neza ibipimo nibiranga, nka VSWR, Ins.Gutakaza, kwigunga, inshuro, ubwoko bwihuza, ubushobozi bwingufu, voltage, ubwoko bwishyirwa mubikorwa, terminal, kwerekana, kugenzura umuzenguruko nibindi bipimo.
Ubwoko bwa Frequency na umuhuza
Tugomba kumenya umurongo wa sisitemu hanyuma tugahitamo coaxial ikwiranye ukurikije inshuro.Umubare ntarengwa wimikorere ya coaxial switch irashobora kugera kuri 67GHz, kandi urukurikirane rutandukanye rwa coaxial rufite imirongo itandukanye ikora.Mubisanzwe, turashobora gusuzuma inshuro ikora ya coaxial switch dukurikije ubwoko bwihuza, cyangwa ubwoko bwihuza bugena inshuro zingana za coaxial switch.
Kuri progaramu ya 40GHz, tugomba guhitamo umuhuza wa 2.92mm.Ihuza rya SMA rikoreshwa cyane murwego rwa frequence muri 26.5GHz.Ibindi bihuza bikunze gukoreshwa, nka N-umutwe na TNC, birashobora gukora kuri 12.4GHz.Hanyuma, umuhuza wa BNC arashobora gukora kuri 4GHz gusa.
DC-6/8 / 12.4 / 18 / 26.5 GHz: Umuhuza wa SMA
DC-40 / 43.5 GHz: 2.92mm ihuza
DC-50/53/67 GHz: 1.85mm umuhuza
Ubushobozi bw'imbaraga
Mubisabwa hamwe no guhitamo ibikoresho, ubushobozi bwimbaraga mubisanzwe nibintu byingenzi.Ni imbaraga zingana iki zishobora kwihanganira kugenwa nubushakashatsi bwububiko, ibikoresho byakoreshejwe, nubwoko bwihuza.Ibindi bintu nabyo bigabanya ubushobozi bwimbaraga za switch, nkinshuro, ubushyuhe bwimikorere nuburebure.
Umuvuduko
Tumaze kumenya ibyinshi mubyingenzi byingenzi bya coaxial switch, kandi guhitamo ibipimo bikurikira biterwa ahanini nibyo umukoresha akunda.
Ihinduka rya coaxial rigizwe na electromagnetic coil na magnet, bikenera voltage ya DC kugirango itware inzira ijyanye na RF inzira.Ubwoko bwa voltage ikoreshwa mugereranya coaxial switch niyi ikurikira:
Umuvuduko w'amashanyarazi
5VDC 4-6VDC
12VDC 13-17VDC
24VDC 20-28VDC
28VDC 24-32VDC
Ubwoko bwa Drive
Muguhindura, umushoferi nigikoresho cya elegitoroniki gihindura imirongo ya RF kuva kumwanya umwe ujya mubindi.Kuri benshi bahinduranya RF, valve ya solenoid ikoreshwa mugukora imashini ihuza imiyoboro ya RF.Iyo duhisemo switch, mubisanzwe duhura nubwoko bune butandukanye bwa drives.
Kunanirwa
Iyo nta voltage yo hanze ikoreshwa, umuyoboro umwe uhora kuri.Ongeraho amashanyarazi yo hanze hanyuma uhindure guhitamo umuyoboro uhuye;Iyo voltage yo hanze ibuze, switch izahita ihinduka kumuyoboro usanzwe uyobora.Niyo mpamvu, birakenewe gutanga amashanyarazi ya DC kugirango akomeze guhinduranya ibyambu.
Gufata
Niba ibyuma bifata ibyuma bikenera kugumya guhinduka, bigomba guhora bitera inshinge kugeza igihe impanuka ya DC yamashanyarazi ikoreshwa kugirango ihindure imiterere.Kubwibyo, Drive Latching Drive irashobora kuguma mumwanya wanyuma nyuma yuko amashanyarazi abuze.
Gufata Kwikuramo
Guhindura bikenera gusa mugihe cyo guhinduranya.Nyuma yo guhinduranya birangiye, hariho icyuma gifunga cyikora imbere muri switch.Muri iki gihe, switch nta kigezweho.Nukuvuga, inzira yo guhinduranya isaba voltage yo hanze.Nyuma yimikorere ihagaze neza (byibuze 50m), kura voltage yo hanze, hanyuma switch igume kumurongo wateganijwe kandi ntabwo izahinduka kumuyoboro wambere.
Gufungura
Ubu buryo bwo gukora SPNT buremewe gusa.Hatabayeho kugenzura voltage, imiyoboro yose yo guhinduranya ntabwo ikora;Ongeramo amashanyarazi yo hanze hanyuma uhindure guhitamo umuyoboro wateganijwe;Iyo voltage yo hanze ari nto, switch igaruka kuri leta ko imiyoboro yose idakora.
Itandukaniro hagati ya Latching na Failsafe
Imbaraga zo kugenzura Failsafe zavanyweho, hanyuma switch ihindurwamo umuyoboro usanzwe ufunze;Latching igenzura voltage yakuweho kandi iguma kumuyoboro watoranijwe.
Iyo habaye ikosa hanyuma ingufu za RF zikabura, hanyuma ugahindura bigomba guhitamo kumuyoboro runaka, Failsafe switch irashobora gutekerezwa.Ubu buryo burashobora kandi gutoranywa niba umuyoboro umwe urimo gukoreshwa naho undi muyoboro ntukoreshwa mubisanzwe, kuko mugihe uhisemo umuyoboro uhuriweho, switch ntikeneye gutanga voltage yumuriro nubu, bishobora kuzamura ingufu.
