Ukwanda kwamanethiwekhi e-4G LTE, ukuthunyelwa kwamanethiwekhi amasha e-5G, kanye nokusabalala kwe-Wi-Fi kuholela ekwandeni okukhulu kwenani lama-band e-radio frequency (RF) okumele amadivayisi angenantambo awasekele. Ibhendi ngayinye idinga izihlungi zokuzihlukanisa ukuze kugcinwe amasignali equkethwe “emzileni” ofanele. Njengoba ithrafikhi ikhula, izidingo zizokhula ukuze kuvunyelwe amasignali ayisisekelo ukuthi adlule ngempumelelo, kuvinjelwe ukuphuma kwebhethri futhi kwandiswe amazinga edatha. Izihlungi zibalulekile kumandla e-bandwidth ebanzi kanye ne-frequency ephezulu, kanti okuyinselele kakhulu yi-Wi-Fi 6E entsha ene-bandwidth engu-6.1MHz kanye ne-frequency ephezulu engu-200.7 GHz.
Njengoba ithrafikhi eyanda isebenzisa ububanzi bemvamisa ye-5GHz - 3GHz ye-7G kanye ne-Wi-Fi, ukuphazamiseka phakathi kwama-band kuzolimaza ukuhlala ndawonye kwalawa ma-wireless technologies athuthukile futhi kunciphise ukusebenza kwawo. Ngakho-ke, kudingeka izihlungi zokusebenza okuphezulu ukuze kulondolozwe ubuqotho bebhendi ngayinye. Ngaphezu kwalokho, inani elilinganiselwe lama-antenna atholakala kumadivayisi eselula kanye nama-AP lizoshayela izinguquko zesakhiwo ukuze kwandiswe ukusetshenziswa kokwabelana nge-antenna, okuzokwandisa izidingo zokusebenza kwezihlungi.
Ubuchwepheshe bokuhlunga kumele buqhubeke nokukhula ukuze kuhlangatshezwane nezidingo ze-Wi-Fi 6 entsha kanye ne-Wi-Fi 6E kanye nokusebenza kwe-5G. Ubuchwepheshe bokuhlunga bangaphambilini obusetshenziswa ezinhlelweni zokusebenza ezingenantambo njenge-Surface Acoustic Wave (SAW), i-Temperature Compensated SAW (TC-SAW), i-Solidly Mounted Resonator-Bulk Acoustic Wave (SMR-BAW), kanye ne-Film Bulk Acoustic Resonators (FBAR) bunganwetshwa kuma-bandwidth abanzi kanye nama-frequency aphezulu kodwa ngezindleko zezinye izinhlaka ezibalulekile njengokulahlekelwa nokuqina kwamandla. Noma, izihlungi eziningi zingamboza ama-bandwidth abanzi, kungaba asetshenziswa kanye nezihlungi ezingezona eze-acoustic noma njengezingxenye eziningi.
Ngokuhlunga okusebenzayo okuphezulu okubuyekeziwe, umphumela uzoba amazinga aphezulu edatha, ukubambezeleka okuphansi, kanye nokumbozwa okunamandla kakhulu. Wonke umuntu uke wabhekana nokuma kwezingcingo zevidiyo, ukulibaziseka kwemidlalo, kanye nokulahlekelwa ukuxhumana endlini ngesikhathi sokusebenza kude okujwayelekile. Ubuchwepheshe obusha be-Wi-Fi obuhlanganiswe namaza amasha e-bandwidth ebanzi avikelwe ukuhlunga okuthuthukisiwe buzohlinzeka ngezixazululo ezihamba phambili. Lezi zihlungi zizosiza ekufezeni amaza e-bandwidth abanzi adingekayo, ukusebenza kwamaza aphezulu, ukulahlekelwa okuphansi, kanye namakhono okuphatha amandla aphezulu. Isibonelo, i-XBAR esekelwe kubuchwepheshe be-resonator be-bulk acoustic wave (BAW). Lawa ma-resonator aqukethe i-single crystal, i-piezoelectric layer, kanye ne-metal tines ebusweni obuphezulu njenge-transducer ye-interdigitated (IDT).
Izihlungi ze-Hybrid integrated integrated passive device (IPD) FBAR Wi-Fi 6E zihlinzeka ngokuvikelwa kokuphazamiseka kuphela kuma-band angu-5 GHz angenalayisensi hhayi kuma-channel angu-5G sub-6GHz noma e-UWB, kuyilapho izihlungi ze-XBAR Wi-Fi 6E zivikela ama-band e-Wi-Fi 6E kuzo zonke izinkinga zokuphazamiseka ezingaba khona.
Izihlungi ze-RF ze-Wi-Fi 7
I-Wi-Fi ihambisana namanethiwekhi eselula ngokuhlangabezana nomthamo kanye nezidingo zesilinganiso sedatha. I-Wi-Fi 6 kanye ne-spectrum ekhuphuke kakhulu kwenza i-Wi-Fi ikhange kakhulu. Kodwa-ke, ukuba khona kwe-Wi-Fi kanye ne-5G kuzodinga izihlungi ukubhekana nezinkinga ezingaba khona zokuphazamiseka. Lezi zihlungi zidinga ukuhlinzeka nge-bandwidth ebanzi, ukusebenza kwemvamisa ephezulu, ukulahlekelwa okuphansi, kanye nokuphathwa kwamandla aphezulu. Njengoba kuqinisekiswe amadivayisi e-Wi-Fi 7 ekuqaleni kuka-2024, isidingo sezihlungi sihlangabezana nezidingo eziqinile sizokhula kakhulu. Ngaphezu kwalokho, ushintsho lwangemva kobhubhane ezindleleni zokuphila nasezindaweni zokusebenza lusho ukuthi kuzoba nezinhlobo ezintsha zamadivayisi kanye nezinhlelo zokusebenza ezifuna idatha.
I-Chengdu Concept Microwave ingumkhiqizi ochwepheshe wezihlungi ze-RF eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/i-band stop, i-duplexer. Zonke zingenziwa ngokwezifiso zakho.
