Kusukela kumafoni ahlakaniphile kuya ezinsizeni zesathelayithi kanye nobuchwepheshe be-GPS RF kuyisici sempilo yesimanje.Igcwele yonke indawo kangangokuthi abaningi bethu bayithatha kalula.
Ubunjiniyela be-RF buyaqhubeka nokuqhuba ukuthuthukiswa komhlaba ezinhlelweni eziningi emikhakheni kahulumeni nezimele.Kodwa intuthuko yezobuchwepheshe ishesha kangangokuthi ngezinye izikhathi kunzima ukubikezela ukuthi umhlaba uzobukeka kanjani eminyakeni embalwa.Kusukela ngo-2000, bangaki abantu ngaphakathi nangaphandle kwemboni abangaqagela ukuthi bazobuka ividiyo esakazwayo kumaselula abo eminyakeni eyi-10?
Ngokumangalisayo, senze intuthuko enkulu kangaka ngesikhathi esifushane, futhi akukho zimpawu zokwehla kwesidingo sobuchwepheshe be-RF obuthuthukisiwe.Izinkampani ezizimele, ohulumeni namabutho emhlabeni wonke bayaqhudelana ukuze babe nezinto ezintsha zakamuva ze-RF.
Kulesi sihloko, sizophendula imibuzo elandelayo: izobukeka kanjani imboni ye-RF eminyakeni eyishumi?Yiziphi izitayela zamanje nezesikhathi esizayo futhi sihlala kanjani phambili?Sibathola kanjani abahlinzeki ababona umbhalo odongeni futhi bazi ukuthi izinto zihamba kanjani?
Amathrendi embonini ye-RF ezayo kanye nekusasa le-RF Technology.Uma ubulokhu unaka intuthuko emkhakheni we-RF, kungenzeka wazi ukuthi inguquko ezayo ye-5g ingenye yezinguquko ezinkulu kakhulu emkhathizwe.Ngo-2027, kuqinisekile ukuthi singalindela ukuthi inethiwekhi ye-5g isiqalile futhi isebenza isikhathi esithile, futhi okulindelwe ngabathengi ngesivinini seselula nokusebenza kuzoba phezulu kakhulu kunamanje.Njengoba abantu abaningi ngokwengeziwe emhlabeni jikelele besebenzisa amafoni ahlakaniphile, isidingo sedatha sizoqhubeka sikhuphuka, futhi ububanzi bomkhawulokudonsa obuvamile obungaphansi kuka-6GHz akwanele ukuhlangabezana nale nselele.Olunye uvivinyo lokuqala lwasesidlangalaleni lwe-5g lukhiqize isivinini esimangalisayo esingu-10 GB ngomzuzwana kufika ku-73 GHz.Akungabazeki ukuthi i-5g izohlinzeka ngombani ngokushesha kumaza asetshenziswa ngaphambilini kuphela kwezempi nezinhlelo zesathelayithi.
Inethiwekhi ye-5g izodlala indima ebalulekile ekusheshiseni ukuxhumana okungenantambo, ukuthuthukisa okungokoqobo okubonakalayo nokuxhuma izigidi zamadivayisi esiwasebenzisayo namuhla.Kuzoba ukhiye wokuvula i-IoT.Imikhiqizo yasendlini ingenakubalwa, izinto zikagesi eziphathwayo, izinto ezigqokekayo, amarobhothi, izinzwa, nezimoto ezizihambelayo zizoxhunywa ngesivinini esingaziwa senethiwekhi.
Lokhu kuyingxenye yalokho u-Eric Schmidt, usihlalo omkhulu wezinhlamvu zamagama, Inc, ayekusho lapho ethi i-inthanethi njengoba siyazi “izonyamalala”;Izoba yonke indawo futhi ihlanganiswe kuwo wonke amathuluzi esiwasebenzisayo kangangokuthi ngeke sikwazi ukuwehlukanisa “nempilo yangempela”.Ukuthuthuka kobuchwepheshe be-RF kuwumlingo okwenza konke lokhu kwenzeke.
Ezempi, i-aerospace ne-satellite application:
Ezweni elinenqubekelaphambili esheshayo kwezobuchwepheshe kanye nokungaqiniseki kwezombangazwe, isidingo sokulondoloza ukuphakama kwezempi sinamandla kunanini ngaphambili.Esikhathini esizayo esiseduze, izindleko zempi ye-elekthronikhi (EW) kulindeleke ukuthi zidlule ama-US $ 9.3 wezigidigidi ngo-2022, futhi isidingo sezempi ye-RF kanye nenqubekelaphambili yobuchwepheshe be-microwave sizokhula kuphela.
Ukugxuma okukhulu phambili kubuchwepheshe “bempi kagesi”
Impi ye-elekthronikhi iwukusebenzisa amandla kazibuthe kagesi (EM) namandla aqondisayo ukulawula i-spectrum kagesi noma ukuhlasela isitha”.(mwrf) osonkontileka abakhulu bezokuvikela bazohlanganisa ubuchwepheshe obuningi bempi kagesi emikhiqizweni yabo eminyakeni eyishumi ezayo.Isibonelo, isilwi esisha sika-Lockheed Martin se-F-35 sinamandla empi kagesi ayinkimbinkimbi, angaphazamisa amaza ezitha futhi acindezele i-radar.
Eziningi zalezi zinhlelo ze-EW ezintsha zisebenzisa amadivaysi e-gallium nitride (GAN) ukusiza ukuhlangabezana nezidingo zawo zamandla ezifunekayo, kanye nezikhulisamsindo eziphansi (LNAs).Ngaphezu kwalokho, ukusetshenziswa kwezimoto ezingenamuntu emhlabeni, emoyeni nasolwandle nakho kuzokwanda, futhi izixazululo ze-RF eziyinkimbinkimbi ziyadingeka ukuze kuxhunyanwe nokulawula le mishini kunethiwekhi yezokuphepha.
Emkhakheni wezempi nakwezohwebo, isidingo sokuxhumana ngesathelayithi ethuthukisiwe (i-SATCOM) izixazululo ze-RF nazo zizokhula.Iphrojekthi ye-WiFi yomhlaba wonke ye-SpaceX iyiphrojekthi efisa kakhulu edinga ubunjiniyela be-RF obuthuthukisiwe.Le phrojekthi izodinga amasathelayithi e-orbit angaphezu kuka-4000 ukuze idlulisele i-inthanethi engenantambo kubantu emhlabeni wonke kwa-Ku no-Ka usebenzisa i-10-30 GHz frequency - ububanzi bebhendi - lena yinkampani nje!
