Izihlungi ze-RF: Izingxenye Ezibalulekile Ezibalulekile Zamadivayisi Okuxhumana Angenantambo

Izihlungi ze-RF, njengezingxenye eziyinhloko zezinhlelo zokuxhumana ezingenazintambo, zifinyelela ukuthuthukiswa kwesignali futhi zithuthukise ikhwalithi yokudlulisela ngokuhlunga ngokukhetha amasignali amafrikhwensi. Ezweni lanamuhla elixhumene kakhulu, indima yeIzihlungi ze-RFayikwazi ukuzitshwa.

Imisebenzi Esemqoka Nezici zeIzihlungi ze-RF

Izihlungi ze-RFingathuthukisa ngempumelelo ukusebenza kahle kwezinhlelo zokuxhumana ngokwenqaba amasignali angafuneki futhi ivumele amasignali amafrikhwensi okuqondiwe ukuthi adlule. Asetshenziswa kakhulu kwezokuxhumana ngeselula, kwezokuxhumana ngesathelayithi, irada, kanye namadivayisi we-inthanethi Yezinto (IoT).

Ukusebenza okuphezuluIzihlungi ze-RFkufanele ibe nalezi zimpawu ezilandelayo:

Ukulahlekelwa kokufaka okuphansi: qinisekisa ukuncipha kwesignali encane ngaphakathi kwebhendi yokungena.

Ukuzihlukanisa okuphezulu kanye nokunciphisa ibhande lokumisa: vimba ngempumelelo amasignali angahlosiwe futhi unciphise ukuphazamiseka.

Inani eliphakeme le-Q: thuthukisa ukukhetha nokunemba kwesihlungi.

Ukusebenza okuhle kakhulu kwe-passive intermodulation (PIM): nciphisa ukuphazamiseka kokuphazanyiswa kwesignali futhi uthuthukise ukuzinza kwesistimu.

Idizayini encane: ukuzivumelanisa nezidingo zemishini yesimanje yezakhiwo ezihlangene ngenkathi iqinisekisa amandla okubamba amandla.

Izinhlobo zeIzihlungi ze-RF

Ngokusekelwe ezintweni zokwakha nezinqubo zokukhiqiza,Izihlungi ze-RFzingahlukaniswa zibe izinhlobo eziningana:
Izihlungi ze-Cavity
Izihlungi ze-Dielectric
Izihlungi ze-Coaxial
Izihlungi ze-Planar
Izihlungi ze-Electroacoustic
Isihlungi ngasinye sinezinzuzo ezihlukile ekuklanyweni, ukusebenza nezimo zohlelo lokusebenza, futhi singahlangabezana nezidingo zamasistimu okuxhumana angenantambo ahlukene.

Amathrendi Emakethe

Ngokuthandwa kwamanethiwekhi e-5G kanye nokwanda kwezicelo kubhendi ye-millimeter wave, isidingo semakethe sokusebenza okuphezulu nokusebenza okuphezulu.Izihlungi ze-RFikhula kancane. Ngaphezu kwalokho, ukukhuphuka kwamadivayisi e-IoT kunikeze namathuba amaningi okuqamba izinto ezintsha zobuchwepheshe kwezihlungi ze-RF.

Ukubaluleka kweIzihlungi ze-RF

Ezinhlelweni zokuxhumana ezingenazintambo, indima yeIzihlungi ze-RFayikhawulelwe ekudluliseni amasiginali athile, kodwa futhi ihlanganisa ukuvikela amaza okuphazamisayo kanye nokuthuthukisa ikhwalithi yesignali. Imishini yesimanje engenawaya idinga izihlungi ezakhiwe ngama-resonators, ama-waveguides noma izingxenye ezingenzi lutho ukuze zisekele imisebenzi yazo yokuxhumana. Yonke idivayisi incike kuyoIzihlungi ze-RFukuqinisekisa ukudluliswa okuphumelelayo nokuthembeka kwamasignali.

Isifinyezo

Njengengxenye eyisisekelo yezinhlelo zokuxhumana ezingenazintambo,Izihlungi ze-RFdlala indima ebalulekile ekusebenzeni kahle kwemishini. Kusukela kuma-smartphones kuya kumasistimu e-radar kuya kumatheminali e-IoT, izindawo zohlelo lokusebenzaIzihlungi ze-RFzanda njalo. Ngokuthuthuka kwezobuchwepheshe kanye nokwanda kwesidingo sokuxhumana okungenantambo,Izihlungi ze-RFizodlala indima ebaluleke nakakhulu emakethe yesikhathi esizayo.
Uma ufuna ikhwalithi ephezuluIsihlungi se-RFizixazululo, singakunikeza ngezinketho ezahlukahlukene ezijwayelekile noma ezenziwe ngezifiso, futhi siphelezele imikhiqizo yakho ngesevisi yewaranti yeminyaka emithathu! Sicela ukhululeke ukuxhumana nathi ukuze uthole ulwazi olwengeziwe.
