Ngobuchwepheshe be-LTE-advanced (LTE-a) nokuvuthwa kancane kancane kwamazinga we-5G, uhlelo lwemvamisa yomsakazo lwemishini yokuxhumana yeselula lubhekene nokuthuthuka okukhulu naseziguqulweni ezinkulu.Ukuze uxhase i-Ultra-ebanzi ye-100mhz, ukusebenza kwama-band angaphezu kwamashumi amane, futhi unciphise umsindo wokuphazamiseka, uhlelo lwabakhiqizi bohlelo ukwandisa ukusetshenziswa kwezakhi zomsakazo zomsakazo ezinjenge-amplifiers yomsindo ophansi (LNA) kanye nama-Amplifiers (PA).Ngasikhathi sinye, amamojula we-Radio Frequency Front-End (Fam) nawo ayacelwa ukuthi athuthukise ukuhlanganiswa okusebenzayo, okushukumisela abakhiqizi be-chip ukusheshisa ukuthuthukiswa kwesizukulwane esisha se-Radio Frequency Solutions.
UMai zhengqi, umqondisi ohambisana ne-Radio Frequency Management Management kanye ne-Enchines-Electronics Division, waveza ukuthi ukukhuphuka kwama-multi-frequency imodi ye-LTE kanye ne-LTE - Imiklamo, abakhiqizi befoni bekhokha kakhulu abahlukahlukeneIzakhi ku-Fam, njenge-PA, LNA, ukushintshwa kanye nezihlungi zibone ukukhuphuka okubukhali okufunwayo.Lolu shintsho luvuse umdlandla we-silicon germanium carbon (SGE: C), Gallium Arsenide (Gaas) kanye nabathengisi be-RF abahambisanayo
Ngaphezu kokuqalwa okugcwele kwe-LTE Commercialization e-United States, eJapan naseNingizimu Korea, i-Mainland China kulindeleke ukuthi ikhiphe amalayisense we-4G engxenyeni yesibili yalo nyaka ukusheshisa ukusebenza kwe-TD-LTE.ITaiwan futhi ilindele ukuthi ikhiphe ngempumelelo amalayisense ngaphambi kokuphela konyaka.Lokhu kuzothuthukisa i-LTE ukuthi ingene isikhathi sokukhula okusheshayo futhi ithuthukise ukuzulazula kwamanye amazwe kanye nokuvama okuhlukahlukene kanye nokucaciswa kwemininingwane eminingi okuhlobene emuva okuhambisana ne-2G / 3G.Ngasikhathi sinye, opharetha we-telecom eSouth Korea nase-United States nabo baqale ukuthengisa i-LTE-a.
Ukuze uhlanganise imisebenzi eminingi yomsakazo esikhaleni esilinganiselwe, umsakazo wemvamisa yomsakazo we-multi-band multi-mode ama-LTE amaselula kufanele asungule isisombululo esihlanganiswe kakhulu sokuklama.Njengamanje, izingcingo zeselula ze-LTE zidinga ukusekela ama-band avama amade ambalwa, nenombolo ye-PA, i-LNA kanye nokushintshwa kwe-RF kuyiphi kabili lelozingcingo ze-3G.Ngokuzayo, njengoba amaselula ekhulisa i-LTE-A ne-5G ngesivinini esiphakeme, ama-bandwidths amakhulu, namabhendi ahlukahlukene ahlukahlukene, ukusetshenziswa kwezinto zomsakazo weRadio kuzokhulisa kakhulu, ukushayela abakhiqizi be-chip ukwenza ngcono imikhiqizo yabo.Ukudidiyelwa ukunciphisa isikhala nokusetshenziswa kwamandla.
IMai zhengqi yahlaziya ukuthi izixazululo ze-Gallium Arsenide RF zinzima ukuhlanganisa nezinye izinto zohlelo ngenxa yenqubo yokukhiqiza.Ngakho-ke, abakhiqizi be-chip basheshisa intuthuko yenqubo yesizukulwane esilandelayo kanye nobuchwepheshe bokupaka.Isibonelo, i-Infiinen igxile kwizinqubo ezibonakalayo ze-silicon germanium carbon ezibonakalayo futhi isihlanganisa ngezixazululo ezincane ezihlangene (i-WLP) ukudala izixazululo ze-mmic ngokusebenza okuphezulu, ukuhlanganiswa okuphezulu nokusekelwa kokushintsha okuvame ukushintshashintsha.I-QUALCOMM ibuye yethule ama-CMOs PA ukuhlanganisa izingxenye eziningi ze-peripheral ngenqubo ye-CMOS.
UMai zhengqi ubuye waveza ukuthi i-Silicon Germanium Carbon ifaniswa ne-gallium arsenide ngokusebenza imvamisa yomsakazo, ikhwalithi kanye nokuthembela, futhi kulula ukuhlanganisa ukushintshwa kwama-CMOS Radio Frequency noma ezinye izinto.Ngakho-ke, umthamo wokuthumela we-Silicon Germanium Carbon Contry ukhule kakhulu eminyakeni yamuva nje, futhi izinga lokungena endaweni ye-MMI LNA lilingana nezakhi ze-Gallium Arsenide.I-Silicon's Silicon Gerbon Carbon MMIC LNA ifake ngempumelelo uhlu lwe-Mediatek's Band Multi-Mode LTE BODE LTE SHODE SHODE SCUCTATION, futhi kulindeleke ukuthi iqhubeke nokukhulisa isabelo sayo semakethe ukusuka ekupheleni kwalo nyaka.
Ngokuqondene ne-PA, uMai zhengqi ukholelwa ukuthi yize izixazululo ze-Gallium Arsenide zisezixazululo ezijwayelekile, i-CMOS PA kulindeleke ukuthi ikhuphuke emakethe yocingo ephansi yeselula esikhathini esizayo ngenxa yokuhlanganiswa kwayo.Ngaphezu kwalokho, i-Infiinen ifake i-silicon gerhon lna plus package ye-PA system (SIP) noma isisombululo sokuhlanganiswa kwe-single-chip ku-bleading yomkhiqizo esizayo ukusiza abakhiqizi befoni behle kakhulu lapho begcina ukusebenza kwemvamisa yomsakazo.
Yize ukucaciswa kwe-LTE-A kanye ne-5G akukanqunywa ngokuphelele, kunamahemuhemu embonini abakhiqizi befoni ephathekayo bangashiya ama-radio frequency avamisile futhi bashintshe ukuklama okuphezulu nokusebenza okuphezulu kwekhwalithi ephezulu.Kulokhu, uMai zhengqi wathi yize abanye abakhiqizi be-Chip be-Radio Frequency bett njengamanje befunda imisebenzi esezingeni eliphezulu ye-Gallium nitride nge-plug-ins nge-plug-ins nge-plug-ins nge-plug-ins nge-plug-ins, ukuhlanganiswa kwengxenye kusesekuyisihluthulelo sokunciphisa izindleko kanye nokonga amandla.Ngakho-ke, kuphela ngemuva kokunqunywa kweZinga lokuxhumana, iphuzu elingcono kakhulu lebhalansi lingatholakala ngokusekelwe kwizidingo zokucaciswa.
