Kugeza ubu 5G yoherejwe harimo sub-6G ya 3 kugeza 5 GHz hamwe na milimetero yumurongo wa 24 GHz cyangwa irenga.Ubwiyongere bwinshuro zitumanaho ntibisaba gusa piezoelectric yibikoresho bya kristu kugirango ihaze, ahubwo bisaba na wafer yoroheje hamwe nu mwanya muto wa interineti wa interineti, bityo rero uburyo bwo guhimba ibikoresho biragoye cyane.Kubwibyo, hejuru ya acoustic filteri yateguwe kuvaLNkristu na lithium tantalate kristal, yakoreshejwe cyane mugihe cya 4G na mbere, ihura naya marushanwa yaubwinshi bwa acousticigikoresho cyo kuzunguruka (BAW) na firime yorohejeubwinshiacoustic resonator(FBAR) mugihe cya 5G.
Ubushakashatsi bwaLNkristu murwego rwo hejuru rwiyungurura rwateye imbere byihuse, kandi tekinoroji yo gutegura ibikoresho nibikoresho iracyerekana imbaraga zikomeye.Muri 2018, Kimura n'abandi.yateguye igikoresho cya 3.5 GHz cyamajwi yamenetse hejuru ya 128 ° Y.LNchip.In 2019 Lu n'abandi.yateguye umurongo wo gutinda ukoreshejeLNfirime imwe ya kristu ifite byibuze igabanuka rya 3.2 dB kuri 2 GHz, irashobora gukoreshwa mugukwirakwiza umurongo mugari wa mobile (eMMB) ya 5G itumanaho.Muri 2018, Yang n'abandi.byateguweLNresonato hamwe na radiyo yo hagati 10.8 GHznaigihombo cyo gushiramo 10. 8 dB;Muri uwo mwaka, Yang n'abandi.yanatangaje 21.4 GHz na 29.9 GHz resonator ishingiyeLNfirime ya kristu, yerekanaga ubushobozi bwaLNkristu mubikoresho byinshyi.Abashakashatsiyizeraga ko ishobora guhaza icyifuzo cya miniaturized imbere-iherezo rya filtri muri K.abande (26.5 ~ 40 GHz) mumurongo wa 5G.Muri 2019, Yang n'abandi.yatangaje C-band muyunguruzi ishingiyeLNfirime imwe ya kristu, ikora kuri 4.5 GHz.
Kubwibyo, hamwe niterambere ryaLNkristu imwenka aibikoresho bya firime yoroheje hamwe nubuhanga bushya bwa acoustic, nkimwe mubikoresho byingenzi byitumanaho rya 5G mugihe kizaza,iImbere-Impera ya RF muyunguruzi ishingiyeLNkristu ifite icyifuzo cyingenzi cyo gusaba.
