Chikamu Chidiki Chinosiyana-siyana Chekushanda Kwepamusoro cheRF Acoustic Devices (LNOSiC)

Substrate Inoshanda Zvakanyanya Kusiyana-siyana yeRF Acoustic Devices (LNOSiC) Mufananidzo Unoratidzwa

Tsananguro pfupi:

Module yeRF front-end chikamu chakakosha chemasisitimu ekukurukurirana emazuva ano, uye maRF filters ndiwo mamwe emabhuroko ayo akakosha. Kushanda kwemaRF filters kunotarisa zvakananga kushandiswa kwespectrum zvakanaka, kuvimbika kwemasaini, kushandiswa kwesimba, uye kuvimbika kwesystem yese. Nekuiswa kwemabhendi e5G NR frequency uye kushanduka kuri kuramba kuchienderera mberi kune mwero wenguva yemberi wewireless, maRF filters anofanirwa kushanda pamafrequency akakwira, bandwidth yakafara, masimba akakwira, uye kugadzikana kwekupisa kuri nani.

Parizvino, mafirita eRF acoustic emhando yepamusoro achiri kuvimba zvakanyanya netekinoroji dzinobva kunze kwenyika, nepo kuvandudzwa kwezvinhu, magadzirirwo emidziyo, uye maitiro ekugadzira ari mashoma. Saka kuwana mhinduro dzeRF filter dzinoshanda zvakanyanya, dzinokwanisa kukura, uye dzisingadhuri kwakakosha zvikuru.

Matambudziko eIndasitiri neTechnical

Mafirita eSurface acoustic wave (SAW) nebulk acoustic wave (BAW) ndiwo matekinoroji maviri anonyanya kushandiswa mumafoni eRF front-end nekuda kwekusarudza kwawo frequency, high quality factor (Q), uye kurasikirwa kwakaderera kwekuisa. Pakati pawo, mafirita eSAW ane mabhenefiti akajeka mumutengo, kukura kwemaitiro, uye kugona kugadzira zvinhu zvakakura, zvichiita kuti zvive mhinduro huru muindasitiri yeRF filter yemuno.

Zvisinei, mafirita eSAW akajairika anosangana nemiganhu yemukati kana akashandiswa kune masisitimu ekukurukurirana e4G ne5G epamusoro, anosanganisira:

Kuwanda kwepakati, zvichideredza kufukidzwa kwe5G NR spectrum yepakati nepamusoro
Q factor haina kukwana, inodzivisa bandwidth uye mashandiro esystem
Kufamba kwekupisa kunodudzwa
Kugona kubata simba shoma

Kukunda zvipingamupinyi izvi uku uchichengetedza mabhenefiti eSAW uye maitiro ayo idambudziko guru rehunyanzvi kune zvishandiso zveRF zvechizvarwa chinotevera.

Uzivi hweKugadzira uye Maitiro eUnyanzvi

Kubva pamaonero emuviri:

Kushanda kwakawanda kwepamusoroinoda acoustic modes ine phase velocity yakakwira pasi pemamiriro akafanana e wavelength
Bandwidth yakafarainoda ma coefficients makuru ekubatanidza emagetsi
Kubata nesimba kwakanyanyazvinoenderana nemidziyo ine simba rakanaka rekupisa, simba remuchina, uye kurasikirwa kweacoustic kwakaderera

Zvichibva pakunzwisisa uku,timu yedu yeinjiniyayakagadzira nzira itsva yekubatanidza yakasiyana-siyana nekubatanidzaMafirimu matete e piezoelectric e single-crystal lithium niobate (LiNbO₃, LN)nesimba repamusoro-soro, simba repamusoro-soro rinotsigira simba remhepo, zvakaita sesilicon carbide (SiC). Chimiro ichi chakabatanidzwa chinonziLNOSiC.

Tekinoroji Yepakati: LNOSiC Substrate Yakasiyana-siyana

Puratifomu yeLNOSiC inopa zvakanakira zvekushanda pamwe chete kuburikidza nekugadzirwa kwezvinhu uye dhizaini yekuvaka:

Kubatanidza Kwakakwirira Kwemagetsi

Firimu rakatetepa reLN rine kristalo imwe chete rinoratidza hunhu hwakanaka hwepiezoelectric, zvichiita kuti mafungu epamusoro acoustic (SAW) nemafungu eGwayana afambe zvakanaka ane ma electromechanical coupling coupling coefficients makuru, nokudaro zvichitsigira dhizaini ye RF filter ye broadband.

Kushanda Kwakawanda uye Kushanda Kwakanyanya KweQ

Kumhanya kwakanyanya kweacoustic substrate inotsigira kunoita kuti mafrequency ekushanda akwire ukuwo ichidzivirira kubuda kweacoustic energy, zvichikonzera kuvandudzwa kwemhando yezvinhu.

Kutarisira Kupisa Kwepamusoro

Zvishandiso zvinotsigira zvakaita seSiC zvinopa mafambiro ekupisa anoshamisa, zvichiwedzera zvakanyanya kugona kwekubata simba uye kugadzikana kwekushanda kwenguva refu pasi pemamiriro emagetsi eRF akakwira.

Kuenderana Kwemaitiro uye Kukura

Chikamu ichi chakasiyana-siyana chinoenderana zvizere nemaitiro aripo ekugadzira SAW, zvichibatsira kutamisa tekinoroji zviri nyore, kugadzira zvinhu zvinokwanisa kukura, uye kugadzira zvinhu zvisingadhuri.

Kuenderana Kwemidziyo uye Mabhenefiti Emazinga Ehurongwa

Iyo LNOSiC substrate yakasiyana inotsigira akawanda maRF acoustic device architectures pane imwe chete material platform, kusanganisira:

Mafirita eSAW akajairika
Midziyo yeSAW inobhadharwa netembiricha (TC-SAW)
Midziyo yeSAW (IHP-SAW) inowedzerwa simba repamusoro inopinzwa mudura
Ma "resonator" e "Lamb wave acoustic" anowanzo shandiswa ne "high-frequency"

Chaizvoizvo, wafer imwe chete yeLNOSiC inogona kutsigirama "multi-band RF filter arrays" anofukidza 3G, 4G, uye 5G applications, kupa chokwadiMhinduro ye "All-in-One" RF acoustic substrateNzira iyi inoderedza kuoma kwehurongwa ukuwo ichigonesa kushanda kwepamusoro uye kuwanda kwekubatanidzwa.

Kukosha Kwehurongwa uye Mhedzisiro Yemaindasitiri

Nekuchengetedza mari uye mabhenefiti eSAW tekinoroji uku uchibudirira zvikuru mukushanda, LNOSiC substrate yakasiyana inopa mukana wenzira inoshanda, inogadzirwa, uye inokwenenzverwakumidziyo yepamusoro yeRF acoustic.

Mhinduro iyi haingotsigire chete kuiswa kukuru mumasisitimu ekutaurirana e4G ne5G asiwo inosimbisa zvinhu zvakasimba uye hwaro hwetekinoroji yemidziyo yeRF acoustic yeramangwana ine mafrequency akakwirira uye ine simba guru. Inomiririra danho rakakosha rekuchinja mafirita eRF epamusoro-soro munyika uye kuzvivimba kwenguva refu kwetekinoroji.

Mibvunzo Inowanzo bvunzwa yeLNOSIC

Mubvunzo 1: LNOSiC inosiyana sei neSAW substrates dzechinyakare?

A:Midziyo yeSAW yakajairika inowanzogadzirwa pamidziyo ye piezoelectric yakawanda, iyo inoderedza frequency, Q factor, uye power handling. LNOSiC inobatanidza firimu reLN rakatetepa rine crystal imwe chete ine substrate ine speed yakakwira, high-thermal-conductivity substrate, zvichiita kuti frequency operation yakakwira, bandwidth yakafara, uye simba rakavandudzwa zvakanyanya uku ichichengetedza SAW process compatibility.

Mubvunzo wechipiri: LNOSiC inoenzaniswa sei neBAW/FBAR technologies?

A:Mafirita eBAW anoshanda zvakanaka pamafrequencies akakwira zvikuru asi anoda maitiro akaoma ekugadzira uye anodhura zvakanyanya. LNOSiC inopa mhinduro yekuwedzera nekuwedzera tekinoroji yeSAW mumabhendi efrequency akakwira ane mutengo wakaderera, kukura kwemaitiro kuri nani, uye kuchinjika kukuru kwekubatanidzwa kwemabhendi akawanda.

Mubvunzo wechitatu: Ko LNOSiC yakakodzera here kushandiswa kwe5G NR?

A:Ehe. Kumhanya kwakanyanya kweacoustic, kubatana kukuru kwemagetsi, uye manejimendi yepamusoro yekupisa kweLNOSiC zvinoita kuti ive yakakodzera mafirita e5G NR epakati nepamusoro, kusanganisira maapplication anoda bandwidth yakakura uye kubata nesimba rakawanda.
