Ukuthunyelwa kwamanje kwe-5G kufaka phakathi ibhendi engaphansi kwe-6G engu-3 ukuya ku-5 GHz kanye nebhendi ye-millimeter wave engu-24 GHz noma ngaphezulu.Ukwanda kwefrikhwensi yokuxhumana akudingi nje kuphela izici ze-piezoelectric zezinto zekristalu ukuthi zaneliswe, kodwa futhi kudinga ama-wafers azacile kanye nesikhala sama-electrode esineminwe emincane, ngakho inqubo yokwenziwa kwemishini inselele kakhulu.Ngakho-ke, izihlungi ze-acoustic ezingaphezulu ezilungiselelwe kusukaLNI-crystal ne-lithium tantalate crystal, eyayisetshenziswa kakhulu enkathini ye-4G nangaphambili, ibhekene nomncintiswanoi-acoustic ngobuningiidivayisi ye-wave (BAW) nefilimu encaneinqwabai-acoustic resonai-tor(FBAR) enkathini ye-5G.

Ucwaningo lweLNIkristalu kusihlungi sefrikhwensi ephezulu yenze inqubekelaphambili ngokushesha, futhi ubuchwepheshe bokulungiselela bezinto zokwakha namadivayisi zisakhombisa amandla amakhulu.Ngo-2018, uKimura et al.ulungise idivayisi yegagasi yomsindo ovuzayo engu-3.5 GHz longitudinal esekelwe ku-128°YLNchip.In 2019 Lu et al.ulungise umugqa wokulibaziseka usebenzisaLNifilimu yekristalu eyodwa enokulahlekelwa okuncane kokufakwa okungu-3.2 dB ku-2 GHz, engasetshenziswa ku-broadband yeselula ethuthukisiwe (eMMB) yokuxhumana kwe-5G.Ngo-2018, u-Yang et al.ilungisiweLNi-resonato ene-central frequency 10.8 GHzfuthiukulahlekelwa kokufaka 10. 8 dB;Ngawo lowo nyaka, uYang et al.iphinde yabika ama-resonators angu-21.4 GHz kanye nama-29.9 GHz ngokusekelweLNifilimu yekristalu, ephinde yabonisa amandla weLNi-crystal kumadivayisi wefrikhwensi ephezulu.Abacwaningiikholelwa ukuthi ingahlangabezana nesidingo sezihlungi ezincane zangaphambili ku-K_aibhendi (26.5 ~40 GHz) kunethiwekhi ye-5G.Ngo-2019, u-Yang et al.kubika isihlungi se-C-band esisekelweLNifilimu yekristalu eyodwa, esebenza ku-4.5 GHz.

Ngakho-ke, ngokuthuthukiswa kweLNikristalu eyodwanjengeimpahla yefilimu emincane kanye nobuchwepheshe obusha bedivayisi ye-acoustic, njengenye yamadivayisi ayisisekelo wokuxhumana kwe-5G esikhathini esizayo,iisihlungi se-RF esisekupheleni okusekelweLNIkristalu inethemba elibalulekile lesicelo.

Ikristalu yekhwalithi ephezulu ye-LN kanye neseli ye-LN Pockels ethuthukiswe yi-WISOPTIC (www.wisoptic.com)
