ʻO ka module RF front-end kahi ʻāpana koʻikoʻi o nā ʻōnaehana kamaʻilio kelepona hou, a ʻo nā kānana RF kekahi o kāna mau poloka kūkulu koʻikoʻi loa. Hoʻoholo pololei ka hana o nā kānana RF i ka pono o ka hoʻohana ʻana i ka spectrum, ka pono o ka hōʻailona, ​​​​ka hoʻohana ʻana i ka mana, a me ka hilinaʻi holoʻokoʻa o ka ʻōnaehana. Me ka hoʻolauna ʻana o nā kaula alapine 5G NR a me ka ulu mau ʻana i nā kūlana uea ʻole e hiki mai ana, pono nā kānana RF e hana manā alapine kiʻekiʻe, nā bandwidth ākea, nā pae mana kiʻekiʻe, a me ka hoʻomaikaʻi ʻana i ke kūpaʻa wela.

I kēia manawa, ke hilinaʻi nui nei nā kānana acoustic RF kiʻekiʻe i nā ʻenehana i lawe ʻia mai, ʻoiai ua kaupalena ʻia ka hoʻomohala kūloko i nā mea hana, nā hoʻolālā hāmeʻa, a me nā kaʻina hana. No laila, he mea nui loa ka hoʻokō ʻana i nā hopena kānana RF hana kiʻekiʻe, hiki ke hoʻonui ʻia, a me ke kumukūʻai kūpono.

Ka ʻIke o ka ʻOihana a me nā Pilikia ʻenehana

ʻO nā kānana nalu acoustic surface (SAW) a me nā kānana nalu acoustic bulk (BAW) nā ʻenehana nui ʻelua i nā noi RF mobile ma muli o ko lākou koho alapine maikaʻi loa, ke kumu kūlana kiʻekiʻe (Q), a me ka pohō hoʻokomo haʻahaʻa. Ma waena o lākou, hāʻawi nā kānana SAW i nā pono maopopo i lokoke kumukūʻai, ka oʻo ʻana o ke kaʻina hana, a me ka hiki ke hana ʻia ma ka nui, e hoʻolilo ana iā lākou i ka hopena nui i ka ʻoihana kānana RF kūloko.

Eia nō naʻe, ke kū nei nā kānana SAW maʻamau i nā palena kūloko i ka wā e hoʻopili ʻia ai i nā ʻōnaehana kamaʻilio 4G a me 5G holomua, me:

  • Alapine waena palena ʻia, e kaupalena ana i ka uhi ʻana o ka spectrum 5G NR waena a me ke kiʻekiʻe

  • ʻAʻole lawa ka Q factor, e kaupalena ana i ka bandwidth a me ka hana ʻōnaehana

  • Ka neʻe ʻana o ka mahana i haʻi ʻia

  • Ka mana lawelawe mana i kaupalena ʻia

ʻO ka lanakila ʻana i kēia mau palena me ka mālama ʻana i nā pono o ke ʻano a me ke kaʻina hana o ka ʻenehana SAW he pilikia loea koʻikoʻi ia no nā polokalamu acoustic RF hanauna e hiki mai ana.

ʻIke Hoʻolālā a me ke ʻAno Hana ʻenehana

Mai kahi hiʻohiʻona kino:

  • ʻOi aku ka pinepine o ka hanakoi i nā ʻano acoustic me ka wikiwiki pae kiʻekiʻe ma lalo o nā kūlana nalu like

  • Ka laulā ākeakoi aku i nā coefficients electromechanical coupling nui aʻe

  • Ka lawelawe ʻana i ka mana kiʻekiʻehilinaʻi ia ma nā substrates me ka conductivity thermal maikaʻi loa, ka ikaika mechanical, a me ka pohō acoustic haʻahaʻa

Ma muli o kēia ʻike,kā mākou hui ʻenekiniaua hoʻomohala i kahi ala hoʻohui heterogeneous hou ma o ka hoʻohui ʻananā kiʻiʻoniʻoni lahilahi piezoelectric lithium niobate kristal hoʻokahi (LiNbO₃, LN)menā substrates e kākoʻo ana i ka wikiwiki leo kiʻekiʻe, ka conductivity wela kiʻekiʻe, e like me ka silicon carbide (SiC). Ua kapa ʻia kēia ʻano i hoʻohui ʻia ʻoLNOSiC.

ʻEnehana Koʻikoʻi: LNOSiC Heterogeneous Substrate

Hāʻawi ka paepae LNOSiC i nā pono hana synergistic ma o ka hoʻolālā like ʻana o nā mea a me ke kūkulu ʻana:

Hoʻopili Electromechanical kiʻekiʻe

Hōʻike ka ʻili lahilahi LN kristal hoʻokahi i nā waiwai piezoelectric maikaʻi loa, e hiki ai ke hoʻoulu maikaʻi ʻia nā nalu acoustic o luna (SAW) a me nā nalu Hipa me nā coefficients electromechanical nui, no laila e kākoʻo ana i nā hoʻolālā kānana RF wideband.

Hana Alapine Kiʻekiʻe a me ka Hana Kiʻekiʻe-Q

ʻO ka wikiwiki acoustic kiʻekiʻe o ke substrate kākoʻo e hiki ai i nā alapine hana kiʻekiʻe aʻe me ka hoʻopau pono ʻana i ka leakage ikehu acoustic, e hopena ana i nā kumu maikaʻi i hoʻomaikaʻi ʻia.

Hoʻokele Wera Kiʻekiʻe

Hāʻawi nā substrates kākoʻo e like me SiC i ka conductivity thermal kūikawā, e hoʻonui nui ana i ka hiki ke lawelawe mana a me ke kūpaʻa hana lōʻihi ma lalo o nā kūlana mana RF kiʻekiʻe.

Ka Hoʻohālikelike ʻana o ke Kaʻina Hana a me ka Scalability

Hoʻohālikelike piha ʻia ka substrate heterogeneous me nā kaʻina hana SAW e kū nei, e hoʻomaʻamaʻa ana i ka hoʻoili ʻenehana maʻalahi, ka hana ʻana i hiki ke hoʻonui ʻia, a me ka hana ʻana me ke kumukūʻai kūpono.

Ka Hoʻohālikelike ʻana o nā Hāmeʻa a me nā Pōmaikaʻi Pae ʻŌnaehana

Kākoʻo ka substrate heterogeneous LNOSiC i nā hoʻolālā hāmeʻa acoustic RF he nui ma kahi kahua mea hoʻokahi, me:

  • Nā kānana SAW maʻamau

  • Nā mea hana SAW i uku ʻia e ka mahana (TC-SAW)

  • Nā mea hana SAW hana kiʻekiʻe (IHP-SAW) i hoʻonui ʻia e ka insulator

  • Nā mea hoʻoheheʻe leo leo alapine (frequency) o ke Keiki hipa

Ma ke kumumanaʻo, hiki i kahi wafer LNOSiC hoʻokahi ke kākoʻonā ʻāpana kānana RF multi-band e uhi ana i nā noi 3G, 4G, a me 5G, e hāʻawi ana i kahi ʻoiaʻiʻoHoʻonā substrate leo RF "All-in-One"Hoʻemi kēia ʻano hana i ka paʻakikī o ka ʻōnaehana ʻoiai e hiki ai ke hana kiʻekiʻe aʻe a me ka nui o ka hoʻohui ʻana.

Ka Waiwai Hoʻolālā a me ka Hopena ʻOihana

Ma ka mālama ʻana i nā pono kumukūʻai a me ke kaʻina hana o ka ʻenehana SAW me ka hoʻokō ʻana i kahi lele nui i ka hana, hāʻawi ka substrate heterogeneous LNOSiC i kahiala kūpono, hiki ke hana ʻia, a hiki ke hoʻonui ʻiae pili ana i nā polokalamu acoustic RF kiʻekiʻe.

ʻAʻole wale kēia hopena e kākoʻo i ka hoʻolaha nui ʻana ma nā ʻōnaehana kamaʻilio 4G a me 5G akā hoʻokumu pū i kahi kahua paʻa o nā mea hana a me nā ʻenehana no nā mea kani RF kiʻekiʻe a me ka mana kiʻekiʻe i ka wā e hiki mai ana. Hōʻike ia i kahi ʻanuʻu koʻikoʻi i ka hoʻololi kūloko o nā kānana RF kiʻekiʻe a me ka hilinaʻi ʻenehana lōʻihi.

Nā nīnau i nīnau pinepine ʻia no LNOSIC

Q1: Pehea ka ʻokoʻa o LNOSiC mai nā substrates SAW maʻamau?

A:Hana pinepine ʻia nā mea hana SAW maʻamau ma nā substrates piezoelectric nui, kahi e kaupalena ai i ke alapine (frequency), Q factor, a me ka lawelawe ʻana i ka mana. Hoʻohui ʻo LNOSiC i kahi ʻili lahilahi LN kristal hoʻokahi me kahi substrate wikiwiki kiʻekiʻe, conductivity thermal kiʻekiʻe, e hiki ai ke hana alapine kiʻekiʻe, bandwidth ākea, a me ka mana mana i hoʻomaikaʻi nui ʻia me ka mālama ʻana i ka hoʻohālikelike ʻana o ke kaʻina hana SAW.

Q2: Pehea e hoʻohālikelike ai ʻo LNOSiC me nā ʻenehana BAW/FBAR?

A:ʻOi aku ka maikaʻi o nā kānana BAW ma nā alapine kiʻekiʻe loa akā koi i nā kaʻina hana paʻakikī a loaʻa nā kumukūʻai kiʻekiʻe. Hāʻawi ʻo LNOSiC i kahi hopena hoʻopihapiha ma ka hoʻonui ʻana i ka ʻenehana SAW i nā hui alapine kiʻekiʻe me ke kumukūʻai haʻahaʻa, ka oʻo ʻana o ke kaʻina hana ʻoi aku ka maikaʻi, a me ka maʻalahi no ka hoʻohui ʻana i nā hui multi-band.

Q3: He kūpono anei ʻo LNOSiC no nā noi 5G NR?

A:ʻAe. ʻO ka wikiwiki acoustic kiʻekiʻe, ka hoʻopili electromechanical nui, a me ka hoʻokele thermal kiʻekiʻe o LNOSiC e kūpono ia no nā kānana 5G NR waena a me ke kiʻekiʻe, me nā noi e koi ana i ka bandwidth ākea a me ka lawelawe ʻana i ka mana kiʻekiʻe.
