Imvamisa yeRelsto Radio (RF)izixhumiIzakhi ezibalulekile zisetshenziswa ezinhlelweni ze-elekthronikhi ezidinga amasiginali afudumele aphezulu. Banikela ngokuxhumeka kukagesi okuphephile phakathi kwamanani amabili e-coaxial anika amandla ukudluliswa kwesiginali okusebenzayo kunhlobonhlobo yezicelo, njengokuxhumana ngocingo, ukusakaza, ukuzulazula kanye nemishini yezokwelapha.
Izixhumi ze-RF zenziwe amasiginali akhuthazelele kakhulu ngaphandle kokuthola noma yimuphi umonakalo kunoma yiliphi ikhebula noma ingxenye futhi ngaphandle kokulahlekelwa amandla. Zenziwe ngokunemba kusetshenziswa izinto ezisezingeni eliphakeme eziqinisekisa ukungazinzile okuzinzile, amandla aqinile omzimba, kanye nokudluliswa kwesiginali efanele.
Kunezinhlobo eziningi zezixhumi ze-RF ezitholakala emakethe, kufaka phakathi i-4.3-10, i-DIN, N, nabanye. Lapha sizoxoxa ngohlobo lwe-N, ngo-4.3-10 uhlobo nohlobo lwe-DINizixhumi.
N izixhumi:N izixhumiziwuhlobo lwesixhumi esine-thwed, esisetshenziswa kakhulu kuzinhlelo zokusebenza ezivame kakhulu. Zilungele kakhulu izintambo zobubanzi obukhulu bobubanzi futhi zingaphatha amazinga aphezulu anamandla.
Izixhumi ze-4.3-10: Isixhumi esingu-4.3-10 yisixhumi esanda kuthuthukiswa ngezakhiwo ezinhle kakhulu zikagesi nezemishini. Inikeza i-PIM ephansi (ukungahambisani nama-passive) futhi ingaphatha amazinga aphezulu amandla. Isixhumi esincane futhi esinamandla kakhulu kunesixhumi se-DIN, okwenza kube kuhle ngezicelo ezindaweni ezinokhahlo. Lezi zixhumi zivame ukusetshenziswa ekuxhumaneni okungenantambo nangokweselula, okusatshalaliswa izinhlelo ze-antenna (DAS), kanye nezinhlelo zokusebenza ze-Broadband.
Izixhumi ze-DH: I-DIN imi ye-Deutsche Industrie Norme. Lezi zixhumi zisetshenziswa kabanzi kulo lonke elaseYurophu futhi zaziwa ngezinga labo eliphakeme lokusebenza nokwethembeka. Ziyatholakala ngosayizi abaningana futhi zivame ukusetshenziswa kuzinhlelo zokusebenza lapho kunesidingo samazinga aphezulu wamandla.Izixhumi ze-DHzivame ukusetshenziswa kuma-antennas, ama-studio okusakaza, kanye nezicelo zezempi.
