Gawo Losayerekezeka Kwambiri la Zipangizo Zakumveka za RF (LNOSiC)

Chojambula Chosiyana Kwambiri cha Zipangizo Zamagetsi za RF (LNOSiC)

Kufotokozera Kwachidule:

Gawo la RF front-end ndi gawo lofunika kwambiri pa njira zamakono zolumikizirana pafoni, ndipo zosefera za RF ndi zina mwa zomangira zake zofunika kwambiri. Kagwiridwe ka ntchito ka zosefera za RF kumatsimikizira mwachindunji momwe magwiritsidwe ntchito a spectrum amagwirira ntchito, kukhulupirika kwa chizindikiro, kugwiritsa ntchito mphamvu, komanso kudalirika kwa makina onse. Ndi kuyambitsidwa kwa ma band a 5G NR frequency komanso kusinthika kosalekeza kupita ku miyezo yamtsogolo yopanda zingwe, zosefera za RF ziyenera kugwira ntchito pama frequency apamwamba, bandwidth yokulirapo, mphamvu zambiri, komanso kukhazikika kwa kutentha.

Pakadali pano, zosefera zapamwamba za RF acoustic zikudalira kwambiri ukadaulo wochokera kunja, pomwe chitukuko cha m'dziko muno cha zipangizo, kapangidwe ka zipangizo, ndi njira zopangira n'chochepa. Chifukwa chake, kukwaniritsa mayankho a RF filter ogwira ntchito bwino, otheka kukula, komanso otsika mtengo ndikofunikira kwambiri.

Mbiri ya Makampani ndi Mavuto a Zaukadaulo

Zosefera za Surface acoustic wave (SAW) ndi bulk acoustic wave (BAW) ndi njira ziwiri zazikulu zogwiritsira ntchito mafoni a RF front-end chifukwa cha kusankha kwawo bwino kwa ma frequency, high quality factor (Q), komanso kuchepa kwa insertion. Pakati pa izi, zosefera za SAW zimapereka ubwino womveka bwino mumtengo, kukhwima kwa ntchito, ndi kuthekera kwakukulu kopanga, zomwe zimapangitsa kuti zikhale njira yodziwika bwino mumakampani opanga zosefera za RF mdziko muno.

Komabe, zosefera zachikhalidwe za SAW zimakhala ndi zoletsa zake zikagwiritsidwa ntchito pamakina apamwamba olumikizirana a 4G ndi 5G, kuphatikiza:

Kuchuluka kwa ma frequency pakati, zomwe zimalepheretsa kufalikira kwa 5G NR spectrum yapakati ndi yapamwamba
Q factor yosakwanira, yoletsa bandwidth ndi magwiridwe antchito a dongosolo
Kusinthasintha kwa kutentha kotchulidwa
Mphamvu yochepa yogwiritsira ntchito mphamvu

Kuthana ndi zopinga izi pamene mukusunga ubwino wa kapangidwe kake ndi njira zomwe zimagwiritsidwa ntchito ndi ukadaulo wa SAW ndi vuto lalikulu laukadaulo pazida zamakono za RF acoustic.

Filosofi Yopanga ndi Njira Yaukadaulo

Kuchokera ku malingaliro akuthupi:

Mafupipafupi ogwirira ntchito apamwambaimafuna njira zoyankhulirana zokhala ndi liwiro lalikulu la gawo pansi pa mikhalidwe yofanana ya kutalika kwa mafunde
Bandwidth yokulirapoimafuna ma coefficients akuluakulu olumikizirana ndi ma electromechanical
Kugwiritsa ntchito mphamvu zambirizimadalira magawo okhala ndi kutentha kwabwino kwambiri, mphamvu yamakina, komanso kutayika kochepa kwa mawu

Kutengera ndi kumvetsetsa kumeneku,gulu lathu la mainjiniyayapanga njira yatsopano yophatikiza yosiyana mwa kuphatikizaMafilimu opyapyala a piezoelectric a single-crystal lithium niobate (LiNbO₃, LN)ndimphamvu ya mawu amphamvu, mphamvu ya kutentha kwambiri yothandizira ma substrates, monga silicon carbide (SiC). Kapangidwe kophatikizana aka kamadziwika kutiLNOSiC.

Ukadaulo Wapakati: LNOSiC Heterogeneous Substrate

Pulatifomu ya LNOSiC imapereka ubwino wogwirizana pogwiritsa ntchito kapangidwe ka zinthu ndi kapangidwe kake:

Kulumikizana Kwambiri kwa Ma Electromechanical

Filimu yopyapyala ya LN yokhala ndi kristalo imodzi imasonyeza mphamvu zabwino kwambiri za piezoelectric, zomwe zimathandiza kuti mafunde a pamwamba pa acoustic (SAW) ndi mafunde a Lamb azigwira ntchito bwino kwambiri pogwiritsa ntchito ma coefficients akuluakulu a electromechanical coupling, motero imathandizira mapangidwe a fyuluta ya RF ya wideband.

Magwiridwe Abwino Kwambiri ndi Kuchita Bwino Kwambiri

Liwiro lalikulu la mawu a gawo lothandizira limapangitsa kuti ma frequency ogwirira ntchito akhale apamwamba kwambiri pomwe limaletsa kutulutsa kwa mphamvu ya mawu, zomwe zimapangitsa kuti zinthu zikhale bwino.

Kusamalira Kutentha Kwambiri

Ma substrates othandizira monga SiC amapereka mphamvu yabwino kwambiri yoyendetsera kutentha, zomwe zimawonjezera kwambiri mphamvu yogwiritsira ntchito mphamvu komanso kukhazikika kwa ntchito kwa nthawi yayitali pansi pa mphamvu ya RF yapamwamba.

Kugwirizana kwa Njira ndi Kukula

Chigawo chosiyanachi chikugwirizana kwathunthu ndi njira zomwe zilipo zopangira SAW, zomwe zimathandiza kusamutsa ukadaulo mosavuta, kupanga zinthu zokulirapo, komanso kupanga zinthu zotsika mtengo.

Kugwirizana kwa Chipangizo ndi Ubwino wa Dongosolo

Gawo losiyana la LNOSiC limathandizira mapangidwe angapo a zida zamawu a RF papulatifomu imodzi, kuphatikiza:

Zosefera za SAW zachizolowezi
Zipangizo za SAW (TC-SAW) zolipiridwa ndi kutentha
Zipangizo za SAW (IHP-SAW) zolimbikitsidwa ndi insulator
Ma resonator amphamvu a Lamb wave acoustic resonators amphamvu kwambiri

Mwachidule, chikwama chimodzi cha LNOSiC chimatha kuthandiziraMa RF filter a multi-band omwe akuphatikizapo mapulogalamu a 3G, 4G, ndi 5G, kupereka chowonadiYankho la "All-in-One" la RF acoustic substrateNjira imeneyi imachepetsa zovuta za dongosolo pamene ikulola kuti magwiridwe antchito apamwamba komanso kuchuluka kwa kuphatikizana kukhale kwakukulu.

Mtengo Wabwino ndi Zotsatira Zamakampani

Mwa kusunga mtengo ndi ubwino wa ukadaulo wa SAW pamene ukukwaniritsa bwino ntchito, gawo losiyana la LNOSiC limaperekanjira yothandiza, yopangidwa, komanso yowonjezedwaku zipangizo zamakono za RF acoustic.

Yankho ili silimangothandiza kufalikira kwakukulu mu njira zolumikizirana za 4G ndi 5G komanso limakhazikitsa zida zolimba ndi ukadaulo wamakono wa zida zamawu a RF zama frequency apamwamba komanso amphamvu kwambiri. Limayimira gawo lofunikira kwambiri pakusinthira ma filters apamwamba a RF m'dziko muno komanso kudzidalira kwaukadaulo kwa nthawi yayitali.

Mafunso Ofunsidwa Kawirikawiri a LNOSIC

Q1: Kodi LNOSiC imasiyana bwanji ndi ma SAW substrates achikhalidwe?

A:Zipangizo za SAW zachizolowezi nthawi zambiri zimapangidwa pogwiritsa ntchito ma substrates a piezoelectric ambiri, zomwe zimachepetsa ma frequency, Q factor, ndi mphamvu. LNOSiC imaphatikiza filimu yopyapyala ya LN yokhala ndi kristalo imodzi yokhala ndi liwiro lapamwamba, kutentha kwambiri, zomwe zimathandiza kuti ma frequency agwire ntchito bwino, bandwidth yayikulu, komanso mphamvu yabwino kwambiri pamene ikusunga kuyenderana kwa njira ya SAW.

Q2: Kodi LNOSiC ikufanana bwanji ndi ukadaulo wa BAW/FBAR?

A:Zosefera za BAW zimagwira ntchito bwino kwambiri pama frequency apamwamba koma zimafuna njira zovuta zopangira ndipo zimawononga ndalama zambiri. LNOSiC imapereka yankho lowonjezera powonjezera ukadaulo wa SAW m'ma frequency apamwamba okhala ndi mtengo wotsika, kukhwima bwino kwa njira, komanso kusinthasintha kwakukulu kophatikizana kwa ma multiband.

Q3: Kodi LNOSiC ndi yoyenera kugwiritsa ntchito 5G NR?

A:Inde. Liwiro lamphamvu la mawu, kulumikizana kwakukulu kwamagetsi, komanso kuyang'anira bwino kutentha kwa LNOSiC kumapangitsa kuti ikhale yoyenera kwambiri pazosefera za 5G NR zapakati komanso zapamwamba, kuphatikiza mapulogalamu omwe amafuna bandwidth yayikulu komanso kugwiritsa ntchito mphamvu zambiri.
