Hawlgelinta 5G ee hadda waxa ka mid ah qayb-6G-hoosaadka 3 ilaa 5 GHz iyo milimitirka hirarka 24 GHz ama ka sareeya.Korodhka soo noqnoqda isgaadhsiinta maaha oo kaliya waxay u baahan tahay sifooyinka piezoelectric ee alaabta crystal si ay u qanciso, laakiin sidoo kale waxay u baahan tahay wafers khafiif ah iyo kala fogaansho yar oo fardaha elektiroonigga ah, sidaas darteed habka wax-soo-saarka aaladaha ayaa si weyn loogu loolama.Sidaa darteed, filtarrada acoustic ee dusha laga diyaariyeyLNcrystal iyo lithium tantalate crystal, kuwaas oo si weyn loo isticmaali jiray waagii 4G iyo ka hor, ayaa wajahaya tartankaacoustic badanQalabka hirarka (BAW) iyo filim khafiif ahbadanresona acoustictor(FBAR) xilligii 5G.

Cilmi-baarista eeLNcrystal in filter soo noqnoqda sare ayaa horumar degdeg ah sameeyey, iyo technology diyaarinta ee alaabta iyo qalabka weli waxay muujinaysaa awood weyn.2018, Kimura et al.waxa la diyaariyay qalab mowjad dhawaaq ah oo soo dareeraya 3.5 GHz oo ku salaysan 128°YLNjajab.In 2019 Lu et al.diyaarisay khadka dib u dhigista adoo isticmaalayaLNhal filim crystal ah oo leh ugu yaraan gelinta 3.2 dB at 2 GHz, kaas oo lagu dabaqi karo kobcinta ballaadhan ee mobilada (eMMB) ee isgaarsiinta 5G.2018, Yang et al.diyaarisayLNresonato la inta jeer ee dhexe 10,8 GHziyoluminta gelinta 10. 8 dB;Isla sanadkaas, Yang et al.Waxa kale oo la sheegay 21.4 GHz iyo 29.9 GHz resonators oo ku salaysanLNfilm crystal, kaas oo sii muujiyay kartida eeLNcrystal ee qalabka soo noqnoqda sare.Cilmi-baarayaashala rumeysan yahay inay dabooli karto baahida filtarrada hore ee la yareeyey ee K_aband (26.5 ~ 40 GHz) ee shabakada 5G.Sanadka 2019, Yang et al.ayaa sheegay shaandhada C-band oo ku salaysanLNhal filim crystal ah, oo ku shaqeeya 4.5 GHz.

Sidaa darteed, iyadoo horumarinta eeLNhal crystalsidaWaxyaabaha filimada khafiifka ah iyo tignoolajiyada cusub ee aaladda acoustic, oo ah mid ka mid ah aaladaha asaasiga ah ee isgaarsiinta 5G mustaqbalka,ahshaandhada RF-dhamaadka hore ku salaysanLNcrystal waxay leedahay rajo codsi muhiim ah.
