Mu myaka ya vuba aha, bitewe n’iterambere ryihuse ry’itumanaho ridafite insinga n’ikoranabuhanga rya radar, kugira ngo hongerwe intera yo kohereza ubutumwa, ni ngombwa kongera imbaraga zo kohereza ubutumwa muri sisitemu. Nk’igice cya sisitemu yose ya mikoroonde, imiyoboro ya RF coaxial igomba kuba ishobora kwihanganira ibisabwa byo kohereza ubutumwa ku bubasha buhanitse. Muri icyo gihe, injeniyeri za RF nazo zigomba gukora ibizamini n’ibipimo by’imbaraga nyinshi, kandi ibikoresho/ibice bya mikoroonde bikoreshwa mu bizamini bitandukanye na byo bigomba kuba bishobora kwihanganira imbaraga nyinshi. Ni ibihe bintu bigira ingaruka ku bubasha bw’imbaraga za mikoroonde coaxial za mikoroonde? Reka turebe.
●Ingano y'umuhuza
Ku bimenyetso bya RF bifite umurongo umwe, imiyoboro minini ifite ubushobozi bwo kwihanganira imbaraga nyinshi. Urugero, ingano y'umwobo w'umuyoboro uhuza ifitanye isano n'ubushobozi bw'umuyoboro, bufitanye isano itaziguye n'imbaraga. Mu miyoboro itandukanye ikoreshwa cyane ya RF coaxial, imiyoboro ya 7/16 (DIN), 4.3-10, na N-type connectors ni minini, kandi ingano y'imiyoboro ijyanye nayo ni nini. Muri rusange, ubushobozi bwo kwihanganira imbaraga z'imiyoboro ya N-type bunganaga na SMA inshuro 3-4. Byongeye kandi, imiyoboro ya N-type connectors ikoreshwa cyane, ari nayo mpamvu ibice byinshi bidakora nka attenuators n'imizigo iri hejuru ya 200W ari imiyoboro ya N-type connectors.
●Inshuro zo gukora
Ubushobozi bwo kwihanganira ingufu za RF coaxial connectors buzagabanuka uko frequency y'ibimenyetso yiyongera. Impinduka mu frequency y'ibimenyetso byo kohereza zituma habaho impinduka mu gihombo n'ikigereranyo cy'umuraba uhagaze, bityo bigira ingaruka ku bushobozi bw'imbaraga zo kohereza n'ingaruka z'uruhu. Urugero, connector rusange ya SMA ishobora kwihanganira ingufu za 500W kuri 2GHz, kandi ingufu zisanzwe zishobora kwihanganira munsi ya 100W kuri 18GHz.
●Igipimo cy'umuraba uhagaze w'amashanyarazi
Umuyoboro wa RF ugena uburebure runaka bw'amashanyarazi mu gihe cyo gushushanya. Mu murongo w'uburebure buto, iyo impedance iranga n'impedance y'umutwaro bitangana, igice cy'amashanyarazi n'umuyoboro uva ku mpera y'umutwaro bigaruka inyuma ku ruhande rw'amashanyarazi, rwitwa umuraba. Imiraba yasubiwemo; voltage n'umuraba uva ku isoko ujya ku mutwaro byitwa imiraba y'impanuka. Umuraba uvamo umuraba wabaye n'umuraba wasubiwemo byitwa umuraba uhagaze. Igipimo cy'agaciro ntarengwa k'amashanyarazi n'agaciro gato k'umuraba uhagaze byitwa igipimo cy'umuraba uhagaze (gishobora kandi kuba coefficient y'umuraba uhagaze). Umuraba wasubiwemo ufata umwanya w'ubushobozi bw'umuyoboro, bigatuma ubushobozi bw'ingufu zo kohereza bugabanuka.
●Igihombo cyo gushyiramo
Gutakaza ingufu mu gushyiramo (IL) bivuga gutakaza ingufu ku murongo bitewe no gushyiramo ibyuma bihuza RF. Bisobanurwa nk'ikigereranyo cy'imbaraga zisohoka n'imbaraga zinjira. Hari ibintu byinshi byongera igihombo cyo gushyiramo ibyuma bihuza, ahanini biterwa na: kudahuza neza kw'impedansi, amakosa yo guteranya neza, icyuho cyo guhuza imiterere y'inyuma y'umuyoboro, kuzunguruka kw'umurongo, guhindagurika kw'umurongo, ubuziranenge bwo gutunganya no gushyiramo amashanyarazi mu mpande, nibindi. Bitewe n'uko hari igihombo, hari itandukaniro hagati y'imbaraga zinjira n'izisohoka, ibyo bizagira ingaruka no ku mbaraga zihoraho.
●Umuvuduko w'umwuka wo mu kirere
Impinduka mu muvuduko w'umwuka zitera impinduka mu gice cy'umwuka gihindagurika, kandi iyo umuvuduko uri hasi, umwuka uhinduka iyoni byoroshye kugira ngo utange korona. Uko uburebure burushaho kuba bwinshi, ni ko umuvuduko w'umwuka uba muke kandi ubushobozi bw'ingufu burushaho kuba buke.
●Ubudahangarwa bw'aho umuntu ahuriye n'aho ahuriye
Ubudahangarwa bw'umuhuza wa RF busobanura ubudahangarwa bw'ingingo z'itumanaho ry'imbere n'iry'inyuma iyo umuhuza uhujwe. Muri rusange uba uri mu rugero rwa milliohm, kandi agaciro kagomba kuba gato uko bishoboka kose. Isuzuma ahanini imiterere y'imikorere y'imihuza, kandi ingaruka zo kudahangarwa n'umubiri no kudahangarwa n'ingingo zisoda bigomba gukurwaho mu gihe cyo gupima. Kuba hariho ubudahangarwa bw'imihuza bizatuma imihuza ishyuha, bigatuma bigorana kohereza ibimenyetso bya mikoroonde binini.
●Ibikoresho bihuriweho
Ubwoko bumwe bw'umuhuza, ukoresheje ibikoresho bitandukanye, buzagira ubushobozi butandukanye bwo kwihanganira.
Muri rusange, ku mbaraga za antene, tekereza ku mbaraga zayo bwite n'imbaraga za connector. Niba ukeneye imbaraga nyinshi, ushoborahinduraumuhuza w'icyuma kitagira umugese, na 400W-500W nta kibazo.
