Imvamisa yomsakazo weTelsto (RF)izixhumiziyizingxenye ezibalulekile ezisetshenziswa ezinhlelweni zokusebenza ze-elekthronikhi ezidinga amasignali avame kakhulu. Zinikeza uxhumano oluphephile lukagesi phakathi kwezintambo ezimbili ze-coaxial futhi zivumela ukudluliselwa kwesignali okuphumelelayo ezinhlobonhlobo zezinhlelo zokusebenza, njengokuxhumana ngocingo, ukusakaza, ukuzulazula, kanye nemishini yezokwelapha.
Izixhumi ze-RF zenzelwe ukubekezelela izimpawu zemvamisa ephezulu ngaphandle kokulimala kwekhebula noma ingxenye futhi ngaphandle kokulahlekelwa amandla. Zenziwa ngokunemba kusetshenziswa izinto ezisezingeni eliphezulu eziqinisekisa ukuqina okuzinzile, amandla aqinile ngokomzimba, kanye nokudluliswa kwesignali okuphumelelayo.
Kunezinhlobo eziningi zezixhumi ze-RF ezitholakala emakethe, okuhlanganisa i-4.3-10, i-DIN, i-N, nezinye. Lapha sizoxoxa ngohlobo lwe-N, uhlobo lwe-4.3-10 kanye nohlobo lwe-DIN.izixhumi.
Izixhumi ze-N:Izixhumi ze-Nziwuhlobo lwesixhumi esinezintambo, esivame ukusetshenziswa ezinhlelweni zemvamisa ephezulu. Zifaneleka kahle kakhulu izintambo ze-coaxial ezinobubanzi obukhulu futhi zingaphatha amazinga aphezulu wamandla.
Izixhumi ze-4.3-10: Isixhumi se-4.3-10 siyisixhumanisi esisanda kuthuthukiswa esinezakhiwo ezinhle kakhulu zikagesi nezemishini. Sinikeza i-PIM ephansi (i-Passive Intermodulation) futhi singaphatha amazinga aphezulu amandla. Siyisixhumi esincane nesiqinile kunesixhumi se-DIN, okwenza sibe yindawo ekahle kakhulu ekusetshenzisweni ezindaweni ezinzima. Lezi zixhumi zivame ukusetshenziswa ekuxhumaneni okungenantambo kanye neselula, izinhlelo ze-antenna ezisatshalaliswa (i-DAS), kanye nezinhlelo zokusebenza ze-broadband.
Izixhumi ze-DIN: I-DIN imele i-Deutsche Industrie Norme. Lezi zixhumi zisetshenziswa kabanzi kulo lonke elaseYurophu futhi zaziwa ngezinga lazo eliphezulu lokusebenza nokuthembeka. Zitholakala ngobukhulu obuhlukahlukene futhi zivame ukusetshenziswa ezinhlelweni zokusebenza lapho kunesidingo samandla aphezulu.Izixhumi ze-DINzivame ukusetshenziswa kuma-antenna, kuma-studio okusakaza, kanye nasezinhlelweni zempi.
