Mu myaka yashize, hamwe niterambere ryihuse ryitumanaho ryitumanaho hamwe na tekinoroji ya radar, kugirango tunonosore intera ikwirakwizwa rya sisitemu, birakenewe kongera imbaraga zo kohereza sisitemu. Nkigice cya sisitemu yose ya microwave, umuhuza wa RF coaxial ugomba kuba ushobora kwihanganira ibyifuzo byogukwirakwiza imbaraga nyinshi. Muri icyo gihe, abajenjeri ba RF bakeneye kandi gukora kenshi ibizamini byimbaraga nimbaraga, kandi ibikoresho bya microwave / ibice bikoreshwa mubizamini bitandukanye nabyo bigomba kuba bishobora guhangana nimbaraga nyinshi. Ni ibihe bintu bigira ingaruka ku bushobozi bw'amashanyarazi ya RF coaxial? Reka turebe
Size Ingano y'umuhuza
Kubimenyetso bya RF byumurongo umwe, abahuza binini bafite kwihanganira imbaraga nyinshi. Kurugero, ingano ya pinhole ihuza ifitanye isano nubushobozi bugezweho bwihuza, bifitanye isano itaziguye nimbaraga. Mubintu bitandukanye bikunze gukoreshwa na RF coaxial ihuza, 7/16 (DIN), 4.3-10, na N-ubwoko bwihuza ni binini mubunini, kandi ubunini bwa pinhole nabwo ni bunini. Mubisanzwe, kwihanganira imbaraga za N-ihuza ni hafi ya SMA inshuro 3-4. Mubyongeyeho, N-ihuza abahuza ikoreshwa cyane, niyo mpamvu ibice byinshi bya pasiporo nka attenuator n'imizigo iri hejuru ya 200W ni N-ihuza.
Frequ Inshuro zakazi
Imbaraga zo kwihanganira imiyoboro ya RF coaxial izagabanuka uko ibimenyetso byiyongera. Imihindagurikire yikimenyetso cyogukwirakwiza biganisha ku mpinduka ziterwa no gutakaza na voltage ihagaze, bityo bikagira ingaruka kubushobozi bwokwirakwiza ningaruka zuruhu. Kurugero, umuhuza rusange wa SMA arashobora kwihanganira ingufu za 500W kuri 2GHz, kandi impuzandengo irashobora kwihanganira munsi ya 100W kuri 18GHz.
●Umuvuduko uhagaze
Umuhuza wa RF yerekana uburebure bw'amashanyarazi mugihe cyo gushushanya. Mumurongo muremure, mugihe ibiranga impedance hamwe nuburemere bwumutwaro bitangana, igice cyumubyigano numuyoboro uva kumitwaro iremereye bigaruka kumurongo wimbaraga, bita umuraba. Imiraba yerekanwe; voltage numuyoboro uva kumasoko kugeza kumitwaro byitwa ibyabaye. Umuhengeri wibisubizo byabaye hamwe numuhengeri ugaragara byitwa umuraba uhagaze. Ikigereranyo cyumubyigano ntarengwa nigiciro ntarengwa cyumurongo uhagaze byitwa voltage ihagaze yumubyigano (birashobora kandi kuba coefficient ihagaze). Umuhengeri ugaragara ufata umwanya wubushobozi bwumuyoboro, bigatuma imbaraga zo kohereza zigabanuka.
●Igihombo
Igihombo cyo gushiramo (IL) bivuga gutakaza imbaraga kumurongo kubera kwinjiza RF ihuza. Byasobanuwe nkikigereranyo cyimbaraga zisohoka nimbaraga zinjiza. Hariho ibintu byinshi byongera igihombo cyinjizwamo, ahanini biterwa na: kudahuza impedance iranga, ikosa ryukuri ryiteranirizo, guhuza icyuho cyanyuma, guhuza umurongo, kuruhande, eccentricité, gutunganya neza na electroplating, nibindi bitewe no kubaho kwigihombo, hari itandukaniro hagati yinjiza nibisohoka imbaraga, nabyo bizagira ingaruka kubushobozi bwo kwihanganira.
●Umuvuduko wo mu kirere
Imihindagurikire yumuvuduko wumwuka itera impinduka muri dielectric ihoraho yumwanya wikirere, kandi kumuvuduko muke, umwuka byoroshye ioni kugirango ubyare corona. Uburebure buri hejuru, niko umuvuduko wumwuka ugabanuka nubushobozi buke.
●Menyesha kuturwanya
Kurwanya guhuza kwihuza rya RF bivuga kurwanya aho uhurira nuyobora imbere ninyuma iyo uhuza. Mubisanzwe ni murwego rwa miliohm, kandi agaciro kagomba kuba gake gashoboka. Isuzuma cyane cyane imiterere yubukorikori bwitumanaho, ningaruka zo kurwanya umubiri hamwe n’abagurisha hamwe bigomba gukurwaho mugihe cyo gupima. Kubaho kwihuza bizatera guhuza gushyuha, bikagora kohereza ibimenyetso binini bya microwave.
●Ibikoresho bihuriweho
Ubwoko bumwe bwihuza, ukoresheje ibikoresho bitandukanye, bizagira kwihanganira imbaraga zitandukanye.
Muri rusange, kubwimbaraga za antenne, tekereza imbaraga zayo nimbaraga zihuza. Niba hari imbaraga zikenewe, urashoboraHinduraumuhuza wibyuma, na 400W-500W ntakibazo.
