Beijing, Nyamavhuvhu 21, 2025-Munzvimbo dziri kusimukira nekukurumidza dzakaita se5G communications, setiraiti internet, uye millimeter-wave radar, RF coaxial connectors zvinhu zvakakosha zvekufambisa kwemasaini, uye kuita kwavo kunokanganisa kugadzikana kwehurongwa hwese. Nekuwedzera kwekudiwa kweakakwira-frequency application, mainjiniya ari kutarisana nematambudziko akanyanya. Munguva pfupi yapfuura, nyanzvi dzeindasitiri dzakapfupikisa matipi mashanu anoshanda ekubatsira mainjiniya kukwenenzvera dhizaini yekubatanidza, kuvandudza kushanda kwekuyedza, uye kuwedzera hupenyu hwemidziyo.
Zano 1: Sarudza Yakakodzera Impedans Matching
Iyo impedance yeRF coaxial connectors (kazhinji 50Ω kana 75Ω) inofanira kunyatsoenderana nehurongwa; kana zvisina kudaro, zviratidzo zvechiratidzo uye kurasikirwa kwesimba zvichaguma. "Mumillimeter-wave frequency mabhendi (semuenzaniso, pamusoro pe28GHz), kunyangwe kutsauka kwechidimbu che 0.1mm kunogona kukonzera kuderera kukuru muSWR," akadaro mumwe director wehunyanzvi pane imwe nyika inogadzira chinongedzo. Mainjiniya anofanirwa kukoshesa kushandisa yakajairwa impedance modhi inopihwa nemugadziri uye kuona iyo chaiyo inofananidzwa vachishandisa vector network analyzer (VNA).
Zano 2: Teerera kuchenesa uye kuchengetedza iyo yekuonana interface.
Connector pini uye zvigadziko zvinowanzoita oxidation uye marara esimbi mushure mekudzokororwa kuiswa uye kubviswa, zvichiita kuti kuwedzere kupikisa kuramba. "Tinokurudzira kushandisa doro-isina donje swab kuchenesa zvinobatika uye kuisa zvivharo zveguruva munzvimbo dzakaoma," akadaro mainjiniya ane chekuita ne6G prototype development. Kune-kuvimbika kwepamusoro (sekuitwa kwemuchadenga), ukobvu hwegoridhe replating hunofanira kudarika 1μm kuti uwedzere kusakara.
Zano 3: Gadzirisa yekuisa torque control.
Kuwedzeredza kana kuomesa pasi kunogona kupfupisa hupenyu hwekubatanidza. Indasitiri data inoratidza kuti torque yakakurudzirwa yeSMA connectors i 0.7-1.0 N · m, nepo 2.92mm kunyatsobatanidza zvibatanidza zvinoda huchokwadi hwe 0.35 N · m. "Kushandisa torque-isina chipanera chinoderedza kukanganisa kwevanhu, izvo zvakanyanya kukosha mukugadzirwa kwehuwandu," akasimbisa R&D maneja wemugadziri wemidziyo yekuyedza.
Zano 4: Kuvandudza kuchengetedzwa kwekudzivirira pamhepo huru.
Mune 5G millimeter wave frequency bhendi, kusakwana kwekubatanidza kudzivirira kushanda kunogona kutungamira kune electromagnetic interference (EMI) nyaya. Zvigadziriso zvichangoburwa zvinosanganisira katatu shielding uye yakaderera-dielectric-constant insulation materials. "Murabhoritari yedu, takaona kuti kuwedzera PTFE (polytetrafluoroethylene) padding kunogona kuvandudza kudzivirira kwekudzivirira nekupfuura 10dB," akadaro mutungamiri wechikwata cheyunivhesiti.
Zano 5: Kurumidza Kugadzirisa Matambudziko
Kana sisitimu ikasangana nemasaini, mainjiniya anogona kushandisa-nhanho nhatu kutsvaga zvinonetsa zvekubatanidza:
1. Kuongorora kwekuona: Cherekedza mapini akabhenda kana kupepeta kweplating;
2. Time domain reflectometry (TDR) kuedza: Tsvaga impedance discontinuities;
3. Kutsiva nzira: Tsiva iyo inofungidzirwa yekubatanidza kuti uone nyaya.
"Kukanganisa kwepamusoro-kunowanzoitika pamakotanisheni matatu ekutanga. Kuisa pamberi penzvimbo idzi kunogona kuchengetedza inodarika 50% yenguva yekugadzirisa matambudziko," anopa zano mumwe injiniya weRF.
Indasitiri Trend: Miniaturization uye yakakwira frequency inoungana mukufanana
Sezvo saizi yepasuru yechip ichidzikira, kudiwa kweakanyanya-makotanidzi madiki, kunyangwe 1.0mm ne0.8mm, kuri kukura nekukurumidza. Panguva imwe cheteyo, waveguide-ku-coaxial conversion tekinoroji inotsigira ma frequency ari pamusoro pe110 GHz yave nzvimbo yekutsvaga nekusimudzira. Vanamazvikokota vanofanotaura kuti vakangwara vanobatanidza neyakasanganiswa tembiricha muripo zvichava zvakajairika mukati memakore mashanu anotevera.
Mhedziso
Kugadzirisa mashandiro eRF coaxial connectors kunoda kubatanidzwa kwakadzama kwedzidziso uye maitiro. Kuziva nzira dziri pamusoro hakungonatsiridza huinjiniya hunobudirira chete asiwo kunoisa hwaro hwakasimba kune-mafarondesheni enhaurirano echizvarwa chinotevera. Sekutaura kwakaita imwe nyanzvi yeindasitiri, "Details inoona kubudirira kana kutadza kwepamusoro-masaini enguva zhinji, uye zvinobatanidza zviri pamwoyo wezvimbo izvi."
