Kev xa tawm 5G tam sim no suav nrog sub-6G band ntawm 3 txog 5 GHz thiab millimeter yoj band ntawm 24 GHz lossis siab dua.Qhov nce ntawm kev sib txuas lus zaus tsis tsuas yog yuav tsum tau lub piezoelectric zog ntawm cov khoom siv lead ua kom txaus siab, tab sis kuj yuav tsum tau thinner wafers thiab me me interfingered electrode spacing, yog li cov txheej txheem fabrication ntawm cov khoom yog heev nyuaj.Yog li ntawd, qhov chaw acoustic lim tau npaj los ntawmLNsiv lead ua thiab lithium tantalate siv lead ua, uas tau siv dav hauv 4G era thiab ua ntej, tab tom ntsib kev sib tw ntawmacoustic ntauwave device (BAW) thiab nyias zaj duab xislojacoustic suabtor(FBAR) hauv 5G era.

Kev tshawb fawb ntawmLNsiv lead ua nyob rau hauv ntau zaus lim tau ua tiav sai, thiab kev npaj technology ntawm cov ntaub ntawv thiab cov cuab yeej tseem qhia tau hais tias muaj peev xwm zoo.Hauv 2018, Kimura et al.npaj lub 3.5 GHz longitudinal leaky suab nto yoj ntaus ntawv raws li 128 ° YLNnti.In 2019 Lu et al.npaj ib txoj kab ncua sivLNib leeg siv lead ua zaj duab xis nrog qhov tsawg kawg nkaus qhov poob ntawm 3.2 dB ntawm 2 GHz, uas tuaj yeem siv rau kev txhim kho mobile broadband (eMMB) ntawm 5G kev sib txuas lus.Xyoo 2018, Yang et al.npajLNresonato nrog nruab nrab zaus 10.8 GHzthiabntxig poob 10. 8 dB;Nyob rau hauv tib lub xyoo, Yang et al.kuj tau tshaj tawm 21.4 GHz thiab 29.9 GHz resonators raws liLNsiv lead ua zaj duab xis, uas ntxiv nthuav qhia lub peev xwm ntawmLNsiv lead ua hauv cov khoom siv ntau zaus.Cov kws tshawb fawbntseeg tias nws tuaj yeem ua tau raws li qhov kev thov rau cov lim dej me me hauv ntej hauv K_aband (26.5 ~ 40 GHz) hauv 5G network.Xyoo 2019, Yang et al.qhia txog C-band lim raws liLNib leeg siv lead ua zaj duab xis, ua haujlwm ntawm 4.5 GHz.

Yog li ntawd, nrog rau txoj kev loj hlob ntawmLNib leeg siv lead uaas acov khoom siv zaj duab xis nyias thiab cov cuab yeej siv suab paj nruag tshiab, ua ib qho ntawm cov khoom siv tseem ceeb ntawm 5G kev sib txuas lus yav tom ntej,tuspem hauv ntej-kawg RF lim raws liLNCrystal muaj ib qho tseem ceeb daim ntawv thov kev cia siab.
