Ukubuka Konke Komkhiqizo

I-RF front-end module iyisici esibalulekile sezinhlelo zokuxhumana zeselula zanamuhla, kanti izihlungi ze-RF ziphakathi kwezici zayo ezibaluleke kakhulu zokwakha. Ukusebenza kwezihlungi ze-RF kunquma ngqo ukusebenza kahle kwe-spectrum, ubuqotho besignali, ukusetshenziswa kwamandla, kanye nokuthembeka kohlelo lonke. Ngokwethulwa kwamabhendi emvamisa ye-5G NR kanye nokuguqukela okuqhubekayo ezindinganisweni ezingenantambo zesikhathi esizayo, izihlungi ze-RF ziyadingeka ukuze zisebenzeamaza aphezulu, ama-bandwidth abanzi, amazinga aphezulu wamandla, kanye nokuzinza okuthuthukisiwe kokushisa.

Njengamanje, izihlungi ze-RF acoustic zezinga eliphezulu zisalokhu zincike kakhulu kubuchwepheshe obungenisiwe, kuyilapho intuthuko yasekhaya ezintweni zokwakha, ukwakheka kwamadivayisi, kanye nezinqubo zokukhiqiza ilinganiselwe. Ngakho-ke, ukufeza izixazululo zezihlungi ze-RF ezisebenza kahle kakhulu, ezikwazi ukulinganiswa, futhi ezingabizi kakhulu kubaluleke kakhulu.

Isizinda Semboni kanye Nezinselele Zobuchwepheshe

Izihlungi ze-Surface acoustic wave (SAW) kanye ne-bulk acoustic wave (BAW) yizo zobuchwepheshe ezimbili ezivelele ezinhlelweni zokusebenza ze-RF eziphathwayo ngenxa yokukhetha kwazo okuhle kakhulu kwemvamisa, i-high quality factor (Q), kanye nokulahlekelwa okuphansi kokufakwa. Phakathi kwazo, izihlungi ze-SAW zinikeza izinzuzo ezicacile ku-izindleko, ukuvuthwa kwenqubo, kanye nokukhiqizwa okukhulu, okwenza kube yisisombululo esiyinhloko embonini yokuhlunga i-RF yasekhaya.

Kodwa-ke, izihlungi ze-SAW ezivamile zibhekene nemikhawulo yangaphakathi uma zisetshenziswa ezinhlelweni zokuxhumana ze-4G kanye ne-5G ezithuthukisiwe, okuhlanganisa:

  • Imvamisa ephakathi nendawo elinganiselwe, ikhawulela ukumbozwa kwe-spectrum ye-5G NR ephakathi nendawo ephezulu

  • I-Q factor enganele, ivimbela i-bandwidth kanye nokusebenza kwesistimu

  • Ukushintshashintsha kwezinga lokushisa okuphinyiselwe

  • Amandla okuphatha amandla alinganiselwe

Ukunqoba lezi zithiyo ngenkathi kulondolozwa izinzuzo zesakhiwo kanye nezinqubo zobuchwepheshe be-SAW kuyinselele ebalulekile yobuchwepheshe kumadivayisi e-RF acoustic esizukulwane esilandelayo.

Ifilosofi Yokuklama kanye Nendlela Yobuchwepheshe

Ngokombono ongokwenyama:

  • Imvamisa yokusebenza ephezulukudinga izindlela ze-acoustic ezinejubane lesigaba esiphezulu ngaphansi kwezimo ezifanayo zobude be-wavelength

  • Umkhawulokudonsa obanziidinga ama-coefficient amakhulu okuhlanganisa ama-electromechanical

  • Ukuphathwa kwamandla aphezulukuncike ezintweni ezingaphansi komhlaba ezine-conductivity enhle kakhulu yokushisa, amandla omshini, kanye nokulahlekelwa okuphansi kwe-acoustic

Ngokusekelwe kulokhu kuqonda,ithimba lethu lobunjiniyelaisungule indlela entsha yokuhlanganisa ehlukahlukene ngokuhlanganisaamafilimu amancane e-piezoelectric e-single-crystal lithium niobate (LiNbO₃, LN)ngeisivinini esiphezulu somsindo, ukuhanjiswa kokushisa okuphezulu okusekelayo, njenge-silicon carbide (SiC). Lesi sakhiwo esihlanganisiwe sibizwa ngokuthiI-LNOSiC.

Ubuchwepheshe Obuyinhloko: I-LNOSiC I-Substrate Engafani

Ipulatifomu ye-LNOSiC inikeza izinzuzo zokusebenza ngokubambisana ngokuklama izinto zokwakha kanye nokwakha:

Ukuxhuma Okuphezulu Kwe-Electromechanical

Ifilimu encane ye-LN enekristalu elilodwa ikhombisa izakhiwo ezinhle kakhulu ze-piezoelectric, ivumela ukuvusa okusebenzayo kwamagagasi e-surface acoustic (SAW) namagagasi e-Lamb anama-coefficients amakhulu okuhlanganisa ama-electromechanical, ngaleyo ndlela isekela imiklamo yesihlungi se-RF se-wideband.

Ukusebenza Okuvame Kakhulu kanye Nokusebenza Okuphezulu Kwe-Q

Ijubane eliphezulu le-acoustic le-substrate esekelayo lenza kube nemvamisa yokusebenza ephezulu ngenkathi kuvimbela ngempumelelo ukuvuza kwamandla e-acoustic, okuholela ezicini zekhwalithi ezithuthukisiwe.

Ukuphathwa Okuphezulu Kokushisa

Ama-substrate asekelayo njenge-SiC ahlinzeka ngokuqhutshwa kokushisa okumangalisayo, okuthuthukisa kakhulu ikhono lokuphatha amandla kanye nokuzinza kokusebenza kwesikhathi eside ngaphansi kwezimo zamandla aphezulu e-RF.

Ukuhambisana Kwenqubo Nokukhula

I-substrate ehlukahlukene ihambisana ngokugcwele nezinqubo zokukhiqiza ze-SAW ezikhona, okwenza kube lula ukudluliselwa kobuchwepheshe okubushelelezi, ukukhiqizwa okukhuliswayo, kanye nokukhiqizwa okungabizi kakhulu.

Ukuhambisana Kwedivayisi kanye Nezinzuzo Zezinga Lesistimu

I-substrate ye-LNOSiC ehlukahlukene isekela ukwakheka kwamadivayisi amaningi e-RF acoustic kupulatifomu eyodwa yezinto ezibonakalayo, okuhlanganisa:

  • Izihlungi ze-SAW ezivamile

  • Amadivayisi e-SAW akhokhelwa izinga lokushisa (TC-SAW)

  • Amadivayisi e-SAW (IHP-SAW) athuthukisiwe nge-insulator (i-IHP-SAW)

  • Ama-resonator e-Lamb wave acoustic asebenza ngesivinini esiphezulu

Empeleni, i-wafer eyodwa ye-LNOSiC ingasekelaama-arrays ezihlungi ze-RF ezinamabhendi amaningi ahlanganisa izinhlelo zokusebenza ze-3G, 4G, kanye ne-5G, enikeza iqinisoIsixazululo se-RF acoustic substrate "Yonke-ku-One"Le ndlela inciphisa ubunzima besistimu ngenkathi ivumela ukusebenza okuphezulu kanye nobuningi obukhulu bokuhlanganiswa.

Inani Lamasu kanye nomthelela Wezimboni

Ngokugcina izindleko kanye nezinzuzo zenqubo yobuchwepheshe be-SAW ngenkathi kufinyelela igxathu elikhulu ekusebenzeni, i-substrate ye-LNOSiC ehlukahlukene inikezaindlela ewusizo, ekhiqizwayo, futhi enwebekayokumadivayisi e-RF acoustic aphezulu.

Lesi sixazululo asigcini nje ngokusekela ukuthunyelwa okukhulu ezinhlelweni zokuxhumana ze-4G kanye ne-5G kodwa futhi sisungula isisekelo sezinto zokwakha kanye nobuchwepheshe esiqinile samadivayisi e-RF acoustic asebenzisa imvamisa ephezulu kanye namandla aphezulu esikhathini esizayo. Simelela isinyathelo esibalulekile sokushintsha izihlungi ze-RF ezisezingeni eliphezulu kanye nokuzimela kwezobuchwepheshe isikhathi eside.
