Substrate ifite imikorere itandukanye cyane ku bikoresho bya RF acoustic (LNOSiC)

Ishusho y'Ishusho Igaragara ku Bikoresho Bikoresha Amajwi ya RF (LNOSiC) Ifite imikorere yo hejuru.

Ibisobanuro bigufi:

Uburyo bwa RF front-end module ni ingenzi cyane muri sisitemu zigezweho z'itumanaho rya telefoni zigendanwa, kandi filters za RF ziri mu by'ingenzi cyane. Imikorere ya filters za RF igena neza ikoreshwa rya spectrum, ubuziranenge bw'ibimenyetso, ikoreshwa ry'ingufu, n'uburyo sisitemu yizewe muri rusange. Hamwe no gushyiraho imirongo ya 5G NR hamwe n'iterambere rihoraho rigana ku bipimo ngenderwaho by'ejo hazaza, filters za RF zirasabwa gukora kurifrequencies nyinshi, bandwidths nini, urwego rw'ingufu ruri hejuru, no kunoza ubushyuhe.

Kugeza ubu, ibyuma biyungurura amajwi bya RF biracyashingiye cyane ku ikoranabuhanga ritumizwa mu mahanga, mu gihe iterambere ry’imbere mu gihugu mu bikoresho, imiterere y’ibikoresho, n’imikorere y’inganda ari rike. Kugera ku bisubizo bya RF filter bifite imikorere myiza, byaguka kandi bihendutse ni ingenzi cyane.

Ishusho irambuye

Incamake y'ibicuruzwa

Inkomoko y'Inganda n'Ingorane za Tekiniki

Imashini zikoresha umurambararo w’amajwi (SAW) n’imashini zikoresha umurambararo w’amajwi (BAW) ni ikoranabuhanga rikuru mu gukoresha ikoranabuhanga rya RF rigendanwa bitewe n’uburyo zikoresha frequency nziza, ubushobozi bwo hejuru (Q), n’uburyo zitakaza ingufu nyinshi. Muri zo, imashini zikoresha umurambararo w’amajwi (SAW) zitanga inyungu zigaragara muriikiguzi, igihe cyo gukora, n'uburyo bunini bwo gukora, bikabagira igisubizo cy’ingenzi mu nganda zitunganya RF mu gihugu.

Ariko, ibyuma bigezweho bya SAW bihura n'imbogamizi iyo bikoreshejwe muri sisitemu zigezweho z'itumanaho rya 4G na 5G, harimo:

Ingano nto yo hagati, igabanya uburyo bwo kugera kuri 5G NR spectrum yo hagati n'iyo hejuru
Q factor idahagije, ibangamira bandwidth n'imikorere ya sisitemu
Ihindagurika ry'ubushyuhe rivugwa
Ubushobozi buke bwo gucunga ingufu

Kurwanya izi mbogamizi no kubungabunga imiterere n'imikorere y'ikoranabuhanga rya SAW ni imbogamizi ikomeye mu bya tekiniki ku bikoresho by'amajwi bya RF byo mu gisekuru gitaha.

Filozofiya yo gushushanya n'uburyo bwa tekiniki

Mu buryo bw'umubiri:

Inshuro nyinshi zo gukorabisaba uburyo bw'amajwi bufite umuvuduko wo hejuru mu gihe cy'uburebure bumwe
Umuyoboro mugari w'itumanahobisaba ko habaho coefficients nini zo guhuza amashanyarazi
Gukoresha imbaraga nyinshibiterwa n'ibintu bifite ubushobozi bwo gutwara ubushyuhe bwiza, imbaraga za mekanike, n'igihombo gito cy'amajwi

Dushingiye kuri ubu buryo bw'ubwumvikane,itsinda ryacu ry'ubwubatsiyateguye uburyo bushya bwo guhuza ibintu butandukanye binyuze mu guhuzaFilime nto za piezoelectric zikozwe muri kristale imwe (LiNbO₃, LN)hamwe naumuvuduko mwinshi w'ijwi, imbaraga zishyigikira ubushyuhe bwinshi, nka silicon carbide (SiC). Iyi miterere ihuriweho yitwaLNOSiC.

Ikoranabuhanga ry'ibanze: LNOSiC Heterogeneous Substrate

Urubuga rwa LNOSiC rutanga inyungu mu mikorere ihuriweho binyuze mu gushushanya ibikoresho n'imiterere:

Guhuza cyane hakoreshejwe amashanyarazi

Filimi nto ya LN ifite kristale imwe igaragaza imiterere myiza ya piezoelectric, ituma habaho gukurura neza imiraba y’ubuso bw’amajwi (SAW) n’imiraba y’intama hamwe n’ibipimo binini bya electromechanical coupling, bityo bigashyigikira imiterere ya RF filter.

Imikorere ya Frequency yo hejuru n'imikorere ya High-Q

Umuvuduko mwinshi w'ijwi ry'urumuri rw'urumuri rufasha mu gukora neza mu gihe bigabanya kumanuka kw'ingufu z'ijwi, bigatuma habaho ibintu byiza kurushaho.

Imicungire myiza y'ubushyuhe

Insinga zishyigikira nka SiC zitanga ubushobozi budasanzwe bwo gutwara ubushyuhe, zikongera cyane ubushobozi bwo gucunga ingufu n'ubudahangarwa bw'imikorere mu gihe kirekire mu gihe cy'ingufu nyinshi za RF.

Guhuza inzira no kwaguka

Iyi substrate itandukanye ijyanye neza n'uburyo bwo gukora SAW buriho, yorohereza ihererekanya ry'ikoranabuhanga mu buryo bworoshye, inganda zikora mu buryo bworoshye, ndetse n'umusaruro uhendutse.

Uburyo Ibikoresho Bihura n'Ibyiza bya Sisitemu

Igice cy’ingenzi cya LNOSiC gishyigikira imiterere myinshi y’ibikoresho bya RF acoustic kuri platform imwe, harimo:

Akayunguruzo ka SAW gasanzwe
Ibikoresho bya SAW bishyuwe n'ubushyuhe (TC-SAW)
Ibikoresho bya SAW (IHP-SAW) bikozwe mu buryo bwo hejuru bifasha mu gukingira
Ibyuma bitanga amajwi bya Lamb wave bikoresha frequency nyinshi

Muri rusange, agace kamwe ka LNOSiC gashobora gushyigikiraibyuma bya RF bifite imiyoboro myinshi bikubiyemo porogaramu za 3G, 4G, na 5G, itanga ukuriIgisubizo cya "All-in-One" RF acoustic substrateUbu buryo bugabanya imiterere y’imikorere ya sisitemu mu gihe butuma habaho imikorere myiza no kwiyongera kw’ubucucike bw’ishyirwa mu bikorwa ry’amakuru.

Agaciro k'ingamba n'ingaruka ku nganda

Mu kubungabunga ikiguzi n'inyungu z'ikoranabuhanga rya SAW mu gihe rigera ku ntambwe ikomeye mu mikorere, LNOSiC substrate itandukanye itangainzira ifatika, ishobora gukorwa, kandi ishobora kwagukaku bikoresho by'amajwi bya RF byo mu rwego rwo hejuru.

Iki gisubizo ntigishyigikira gusa ishyirwa mu bikorwa rinini rya sisitemu z'itumanaho za 4G na 5G, ahubwo kinashyiraho ibikoresho n'ishingiro rikomeye ry'ikoranabuhanga ku bikoresho by'amajwi bya RF bikoresha amajwi menshi kandi bifite imbaraga nyinshi mu gihe kizaza. Ni intambwe ikomeye mu gusimbuza ama-filters ya RF yo mu gihugu no kwishingikiriza ku ikoranabuhanga mu gihe kirekire.

Ibibazo Bikunze Kubazwa kuri LNOSIC

Q1: Ni gute LNOSiC itandukanye n'ibice bisanzwe bya SAW?

A:Ibikoresho bisanzwe bya SAW bikunze gukorwa ku bikoresho bya piezoelectric byinshi, bigabanya frequency, Q factor, no gukoresha ingufu. LNOSiC ihuza filime nto ya LN ifite umuvuduko mwinshi, ifite thermal-conductivity, ituma frequency ikora neza, bandwidth yagutse, kandi ikagira ubushobozi bwo kongera ingufu mu gihe igumana imikorere ya SAW.

Q2: Ni gute LNOSiC igereranywa n'ikoranabuhanga rya BAW/FBAR?

A:Imashini ziyungurura za BAW zirakora neza cyane ku murongo wo hejuru cyane ariko zisaba inzira zigoye zo gukora kandi zitwara amafaranga menshi. LNOSiC itanga igisubizo cyuzuzanya binyuze mu kwagura ikoranabuhanga rya SAW mu mirongo yo hejuru y’umurongo hamwe n’igiciro gito, iterambere ryiza ry’imikorere, no koroshya ikoreshwa ry’imirongo myinshi.

Q3: Ese LNOSiC ikwiriye gukoreshwa muri porogaramu za 5G NR?

A:Yego. Umuvuduko mwinshi w'amajwi, guhuza cyane kw'amashanyarazi, hamwe n'imicungire myiza y'ubushyuhe bwa LNOSiC bituma ikoreshwa neza mu kuyungurura 5G NR mu buryo bwo hagati n'ubwo hejuru, harimo porogaramu zisaba bandwidth nini no gucunga ingufu nyinshi.
