Kuchuluka kwa ma netiweki a 4G LTE, kukhazikitsidwa kwa ma netiweki atsopano a 5G, ndi kuchuluka kwa Wi-Fi kukuwonjezera kuchuluka kwa ma band a wailesi (RF) omwe zipangizo zopanda zingwe ziyenera kuthandizira. Band iliyonse imafuna zosefera kuti zisungidwe kuti zizindikiro zisungidwe mu "njira" yoyenera. Pamene kuchuluka kwa magalimoto kukuwonjezeka, zofunikira zidzakula kuti zizindikiro zofunika zidutse bwino, kuletsa kutaya kwa batri ndikuwonjezera kuchuluka kwa deta. Zosefera ndizofunikira kwambiri pa bandwidth yayikulu komanso kuthekera kwa ma frequency apamwamba, ndipo chovuta kwambiri ndi Wi-Fi 6E yatsopano yokhala ndi bandwidth ya 6.1MHz ndi frequency yayikulu ya 200.7 GHz.
Popeza kuchuluka kwa magalimoto kumagwiritsa ntchito ma frequency a 5GHz - 3GHz pa 7G ndi Wi-Fi, kusokonezana pakati pa ma band kudzasokoneza mgwirizano wa ukadaulo wapamwamba wopanda zingwewu ndikuchepetsa magwiridwe antchito awo. Chifukwa chake, ma filters apamwamba amafunika kuti gulu lililonse likhale lolimba. Kuphatikiza apo, kuchuluka kochepa kwa ma antenna omwe amapezeka m'mafoni ndi ma AP kudzayambitsa kusintha kwa kapangidwe kake kuti kuwonjezere kugwiritsa ntchito ma antenna, zomwe zidzawonjezera kufunika kwa magwiridwe antchito a fyuluta.
Ukadaulo wa zosefera uyenera kupitilizabe kusintha kuti ukwaniritse zofunikira za Wi-Fi 6 ndi Wi-Fi 6E yatsopano komanso ntchito ya 5G. Ukadaulo wakale wa zosefera womwe umagwiritsidwa ntchito mu mapulogalamu opanda zingwe monga Surface Acoustic Wave (SAW), Temperature Compensated SAW (TC-SAW), Solidly Mounted Resonator-Bulk Acoustic Wave (SMR-BAW), ndi Film Bulk Acoustic Resonators (FBAR) ukhoza kukulitsidwa ku ma bandwidth okulirapo komanso ma frequency apamwamba koma popanda zinthu zina zofunika monga kutayika ndi kulimba kwa mphamvu. Kapena, zosefera zingapo zimatha kuphimba ma bandwidth okulirapo, mwina kugwiritsidwa ntchito limodzi ndi zosefera zosakhala za acoustic kapena ngati magawo angapo.
Ndi kusefa kwapamwamba kwatsopano, zotsatira zake zidzakhala kuchuluka kwa deta, kuchepa kwa nthawi yochedwetsa, komanso kufalikira kwamphamvu kwambiri. Aliyense wakhala akukumana ndi kuyimitsa mafoni apakanema, kuchedwa kwa masewera, komanso kutayika kwa kulumikizana m'nyumba panthawi yogwira ntchito kutali. Ukadaulo watsopano wa Wi-Fi wophatikizidwa ndi ma frequency atsopano a bandwidth otetezedwa ndi kusefa kwapamwamba kudzapereka mayankho opita patsogolo. Zosefa izi zithandiza kukwaniritsa ma bandwidth ofunikira, kugwiritsa ntchito ma frequency ambiri, kutayika kochepa, komanso kuthekera kogwiritsa ntchito mphamvu zambiri. Mwachitsanzo, XBAR yochokera kuukadaulo wa resonator wa bulk acoustic wave (BAW). Ma resonator awa ali ndi kristalo imodzi, piezoelectric layer, ndi zitsulo pamwamba ngati transducer ya interdigitated (IDT).
Zosefera za Hybrid integrated passive device (IPD) FBAR Wi-Fi 6E zimapereka chitetezo chosokoneza ma band a 5 GHz osavomerezeka okha osati ma channel a 5G sub-6GHz kapena UWB, pomwe zosefera za XBAR Wi-Fi 6E zimateteza ma band a Wi-Fi 6E ku mavuto onse omwe angasokonezedwe.
Zosefera za RF za Wi-Fi 7
Wi-Fi imathandizira ma netiweki am'manja pokwaniritsa kuchuluka kwa deta komanso kufunikira kwa data. Wi-Fi 6 ndi kuchuluka kwa ma sipekitiramu kumapangitsa Wi-Fi kukhala yokongola kwambiri. Komabe, kukhalapo kwa Wi-Fi ndi 5G kudzafuna zosefera kuti zithetse mavuto omwe angabuke. Zosefera izi ziyenera kupereka bandwidth yayikulu, kugwiritsa ntchito pafupipafupi kwambiri, kutayika kochepa, komanso kugwiritsa ntchito mphamvu zambiri. Ndi chitsimikizo cha zida za Wi-Fi 7 zomwe zikuyembekezeka kumayambiriro kwa chaka cha 2024, kufunikira kwa zosefera kukwaniritsa zofunikira kwambiri kudzawonjezeka. Kuphatikiza apo, kusintha kwa moyo pambuyo pa mliri m'malo ogwirira ntchito kumatanthauza kuti padzakhala mitundu yatsopano ya zida ndi mapulogalamu omwe akufuna deta.
Chengdu Concept Microwave ndi kampani yopanga ma RF fyuluta ku China, kuphatikizapo fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
