Izixhumi ze-RF (Radio Frequency) zidlala indima ebalulekile ekwenzeni ukuxhumana okungenazihibe kanye nokudlulisa kuzo zonke izimboni.Lezi zixhumi zisiza ukuqinisekisa ukugeleza okuthembekile kwezimpawu, ukuhlinzeka ngoxhumano oluqinile noluzinzile phakathi kwamadivayisi.Zaziwa ngokusebenza kwazo okuphezulu nokuguquguquka, izixhumi ze-RF seziphenduke izinto ezibalulekile ezimbonini ezifana nezokuxhumana, ezezindiza, nokunakekelwa kwezempilo.Khipha amandla ezixhumi ze-RF: ezokuxhumana: Ezweni lezokuxhumana elisheshayo, izixhumi ze-RF zihamba phambili, zenza kube lula ukudluliswa kwedatha namasignali ngempumelelo.Kungakhathaliseki ukuthi kudlulisa izwi, ividiyo noma amasignali edatha kuwo wonke amanethiwekhi amakhulu, izixhumi ze-RF ziqinisekisa ukulahlekelwa okuncane nokuphazanyiswa, ngaleyo ndlela kugcinwe ubuqotho bohlelo lwezokuxhumana.Ikwazi ukuphatha ububanzi befrikhwensi ephezulu, izixhumi ze-RF zibalulekile emibhoshongweni yamaseli, amasathelayithi, amarutha kanye nezinye izinto zokusebenza zokuxhumana ngocingo, okuqinisekisa ukuxhumana okungaphazamiseki kwezigidigidi zabasebenzisi emhlabeni jikelele.I-Avionics: Imboni yezokundiza ithembele kakhulu kuzixhumi ze-RF ukuze zinike amandla ukuxhumana okuphephile nokushintshisana kwedatha phakathi kwezinhlelo zezindiza.Izixhumi ze-RFidlala indima ebalulekile ezinhlelweni zezindiza, okuhlanganisa izinhlelo ze-radar, imishini yokuhamba, kanye nemishini yezokuxhumana.Lezi zixhumi zimelana nezimo zemvelo ezinzima, okuhlanganisa izinga lokushisa elidlulele, ukudlidliza kanye nokuphazamiseka kazibuthe kagesi, okuqinisekisa amazinga aphezulu okuthembeka nokuphepha emisebenzini yezindiza.
ukunakekelwa kwezempilo: Ekunakekelweni kwezempilo, izixhumi ze-RF zibalulekile emishinini yezokwelapha namadivayisi.Kusukela kuzikena ze-MRI nemishini ye-ultrasound kuya kumasistimu okuqapha isiguli namadivayisi okuxhumana angenantambo, izixhumi ze-RF ziqinisekisa ukunemba nobuqotho bokudluliswa kwedatha yezokwelapha.Lezi zixhumi zihlanganisa amandla emvamisa ephezulu namazinga okuphepha aqinile ukuze kuqinisekiswe ukusebenza okungenazihibe kwemishini ebalulekile ekuxilongweni kwesiguli, ukwelashwa nokunakekelwa.I-IoT namadivayisi ahlakaniphile: Ngokukhula kokuduma kwe-inthanethi Yezinto (IoT) namadivayisi ahlakaniphile, izixhumi ze-RF ziyingxenye ebalulekile ekusunguleni ukuxhumana phakathi kwamadivayisi enethiwekhi.Kusukela kumadivayisi ahlakaniphile asekhaya kuya kubuchwepheshe obugqokekayo, izixhumi ze-RF zinika amandla amadivayisi ukuthi axhumane futhi abelane ngedatha ngaphandle kwentambo, okudala indawo exhumeke kakhudlwana nesebenza kahle.Usayizi ohlangene nokusebenza okuphezulu kwezixhumi ze-RF kuzenza zilungele ukuhlanganiswa kumadivayisi amancane ngaphandle kokuphazamisa amandla esignali noma ukwethembeka.Khetha isixhumi esilungile se-RF: Ukukhetha isixhumi se-RF esifanele sohlelo oluthile kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuhambisana.
Izinto okufanele zicatshangelwe zihlanganisa ububanzi befrikhwensi, i-impedance, ukuqina, uhlobo lwepulaki kanye nezidingo zemvelo.Kunezinhlobo eziningi zezixhumi ze-RF, njengezixhumi ze-SMA, BNC, N, ne-TNC, ngakho-ke kubalulekile ukubonisana nochwepheshe onolwazi noma ubhekisele kumazinga emboni ukuze wenze isinqumo unolwazi.Ekuphetheni:Izixhumi ze-RFzingamandla ashayelayo ekuxhumekeni okungenamthungo kanye nokudluliswa kwamasignali okuphumelelayo ezimbonini ezihlukahlukene.Ikhono labo lokuphatha amasiginali wemvamisa ephezulu, ukumelana nezindawo ezinokhahlo kanye nokuhlinzeka ngoxhumano oluvikelekile libenza babaluleke kakhulu kwezokuxhumana, izindiza, ukunakekelwa kwezempilo kanye ne-inthanethi Yezinto.Njengoba ubuchwepheshe buqhubeka buthuthuka, isidingo sezixhumi ze-RF ezimazombezombe nezithembekile sizoqhubeka nokukhula, sisekela isisekelo sezinhlelo zokuxhumana zesimanje kanye nokwenza ngcono ukuxhumana emhlabeni jikelele.
