Pfupi Ongororo yeLithium Niobate Crystal uye Zvishandiso Zvayo - Chikamu 8: Iyo Acoustic Kushandisa kweLN Crystal

Ikozvino 5G deployment inosanganisira sub-6G bhendi ye3 kusvika 5 GHz uye millimeter wave bhendi ye24 GHz kana kupfuura.Kuwedzera kwemafafitera ekutaurirana hakungodi kuti piezoelectric zvimiro zvekristaro zvinhu zvigutsikane, asi zvinodawo mawafer matete uye madiki interfingered electrode spacing, saka maitiro ekugadzira emidziyo anoshorwa zvakanyanya.Naizvozvo, iyo yepamusoro acoustic mafirita akagadzirirwa kubvaLNcrystal uye lithium tantalate crystal, iyo yaishandiswa zvakanyanya munguva ye4G uye mberi, yakatarisana nemakwikwi e.bulk acousticwave mudziyo (BAW) uye firimu rakatetepazvakawandaacoustic resonator(FBAR) munguva ye5G.

Tsvakurudzo yeLNcrystal in high frequency filter yafambira mberi nekukurumidza, uye tekinoroji yekugadzirira yezvishandiso nemidziyo ichiri kuratidza kugona kukuru.Muna 2018, Kimura et al.yakagadzira 3.5 GHz longitudinal leaky inonzwika pamusoro pemhepo wave mudziyo wakavakirwa pa128 ° YLNchip.In 2019 Lu et al.gadzirira mutsara wekunonoka uchishandisaLNfirimu rekristaro rimwechete rine kushomeka kwekuisa kurasikirwa kwe3.2 dB pa2 GHz, iyo inogona kuiswa kune yakagadziridzwa mobile Broadband (eMMB) ye5G kutaurirana.Muna 2018, Yang et al.yakagadzirirwaLNresonato nepakati frequency 10.8 GHzuyekuisa kurasikirwa 10. 8 dB;Mugore rimwe chetero, Yang et al.zvakare yakashuma 21.4 GHz uye 29.9 GHz resonators zvichibva paneLNfirimu rekristaro, iro rakaratidza zvakare kugona kweLNcrystal mune yakakwira frequency zvishandiso.Vatsvakurudziaitenda kuti yaigona kusangana nezvinodiwa zveminiaturized kumberi-kumagumo mafirita muKabhendi (26.5 ~ 40 GHz) mu5G network.Muna 2019, Yang et al.yakashuma C-bhendi sefa yakavakirwa paLNsingle crystal film, inoshanda pa4.5 GHz.

Naizvozvo, nekuvandudzwa kweLNkristaro imwe chetese adzakatetepa firimu zvinhu uye nyowani acoustic mudziyo tekinoroji, seimwe yepakati michina ye5G kutaurirana mune ramangwana,thekumberi-kumagumo RF sefa yakavakirwa paLNcrystal ine tarisiro yakakosha yekushandisa.
