Izihlungi ze-RF, njengezakhi eziyinhloko zezinhlelo zokuxhumana ezingenantambo, zuza ukusebenza kahle kwesiginali futhi uthuthukise ikhwalithi yokudlulisela ngokukhetha amasiginali wemvamisa. Emhlabeni wanamuhla oxhumeke kakhulu, indima yeIzihlungi ze-RFayinakunakwa.
Imisebenzi ebalulekile nezici zeIzihlungi ze-RF
Izihlungi ze-RFIngathuthukisa ngempumelelo ukusebenza kahle kwezinhlelo zokuxhumana ngokwenqaba amasiginali angafuneki futhi kuvumela amasiginali avamisile okuhlosiwe. Zisetshenziswa kabanzi ekuxhumaneni kweselula, ezokuxhumana se-satellite, i-radar, kanye ne-inthanethi yezinto (amadivayisi we-IOT).
Ukusebenza okuphezuluIzihlungi ze-RFkufanele ibe nezimpawu ezilandelayo:
Ukulahleka kokufakwa okuphansi: Qinisekisa ukufakwa kwesiginali okuncane ngaphakathi kwephasiband.
Ukuhlukaniswa okuphezulu kanye ne-stopbation ephakeme: Vimba ngempumelelo amasiginali angewona amathagethi futhi unciphise ukuphazamiseka.
Inani eliphakeme le-Q: Thuthukisa ukukhetha nokunemba kwesihlungi.
Ukusebenza okuhle kwe-Passive Imentmodation (PIM): Yehlisa ukuphazamiseka kokuhlangana kwesiginali futhi uthuthukise ukuqina kohlelo.
Idizayini encane: Zivumelanisa nezidingo zamadivayisi wanamuhla wezakhiwo ezihlangene ngenkathi uqinisekisa amandla okuphatha amandla.
Izinhlobo zeIzihlungi ze-RF
Kususelwa ezintweni zokwakha nezinqubo zokukhiqiza,Izihlungi ze-RFingahlukaniswa ngezinhlobo eziningana:
Izihlungi zeCavity
Izihlungi ze-Dielectric
Izihlungi ze-COAXIAL
Ukuhlunga kwePlaman
Izihlungi ze-Electroacoustic
Isihlungi ngasinye sinezinzuzo ezihlukile ekwakhiweni, ekusebenzeni nasezimweni zohlelo lokusebenza, futhi zingahlangabezana nezidingo zezinhlelo ezihlukile zokuxhumana ezingenantambo.
Izitayela Zemakethe
Ngokuthandwa kwamanethiwekhi we-5G kanye nokwanda kwezicelo ku-millimeter wave band, isidingo semakethe sokuvama okuphezulu nokusebenza okuphezuluIzihlungi ze-RFiyakhula ngokuqinile. Ngaphezu kwalokho, ukukhuphuka kwamadivayisi we-IOT kubuye kunikeze amathuba amaningi okuqala kwezobuchwepheshe kwezihlungi ze-RF.
Ukubaluleka kweIzihlungi ze-RF
Ezinhlelweni zokuxhumana ezingenantambo, indima yeIzihlungi ze-RFAkukhawulelwe ekuphasiseni amasiginali athile athile, kepha futhi kufaka nokuvikela imvamisa yokuphazamisa kanye nokwenza kahle ikhwalithi yesiginali. Amadivayisi anamuhla angenantambo adinga izihlungi ezakhiwe ngabathengisi, ama-wavegcuides noma izingxenye ezingezinhle ukusekela imisebenzi yabo yokuxhumana. Yonke insiza incikeIzihlungi ze-RFukuqinisekisa ukudluliselwa okusebenzayo kanye nokwethenjwa kwezimpawu.
Ukubeka kafushane
Njengengxenye eyisisekelo yezinhlelo zokuxhumana ezingenantambo,Izihlungi ze-RFDlala indima ebalulekile ekusebenzeni kahle kwamadivayisi. Kusuka kuma-Smartphones kuya ku-radar systems kuma-iot terminals, izindawo zohlelo lokusebenzaIzihlungi ze-RFzikhula njalo. Ngokuthuthuka kobuchwepheshe kanye nokwanda kwesidingo sokuxhumana okungenantambo,Izihlungi ze-RFizodlala indima ebaluleke ngokwengeziwe emakethe yesikhathi esizayo.
Uma ufuna ikhwalithi ephezuluIsihlungi se-rfIzixazululo, singakunikeza ngezinketho eziningi ezijwayelekile noma ezenziwe ngezifiso, bese uphelezela imikhiqizo yakho ngensizakalo yewaranti yeminyaka emithathu! Sicela uzizwe ukhululekile ukuxhumana nathi ukuthola eminye imininingwane.
