Sezvatinoziva tese, coaxial tambo ndeye Broadband yekufambisa tambo ine yakaderera kurasikirwa uye yakanyanya kuzviparadzanisa nevamwe.Iyo coaxial tambo ine maviri concentric cylindrical conductor akapatsanurwa ne dielectric gaskets.Capacitance uye inductance yakagoverwa pamwe neiyo coaxial mutsara inoburitsa impedance yakagoverwa muchimiro chese, chinoti hunhu impedance.
Kurasika kwekupokana pamwe nekoaxial tambo kunoita kuti kurasikirwa uye hunhu pamwe netambo kufungidzira.Pasi pezvakasanganiswa mhedzisiro yezvinhu izvi, kurasikirwa kwecoaxial tambo kana uchifambisa magetsi emagetsi (EM) simba ishoma pane iyo yeantenna munzvimbo yemahara, uye kupindira kwacho kushoma.
(1) Chimiro
Coaxial cable zvigadzirwa zvine yekunze conductive shielding layer.Mamwe matanda anogona kushandiswa kunze kweiyo coaxial tambo yekuvandudza kuchengetedzwa kwezvakatipoteredza kuita, EM kudzivirira kugona uye kuchinjika.Coaxial tambo inogona kugadzirwa neyakarukwa conductor yakasungwa waya, uye nehungwaru yakaturikidzana, iyo inoita kuti tambo ive yakanyanya kuchinjika uye kurongekazve, yakareruka uye yakasimba.Chero bedzi iyo cylindrical conductor ye coaxial tambo ichichengetedza concentricity, kukotama uye kutsauka hazvizokanganisa kuita kwetambo.Naizvozvo, coaxial tambo dzinowanzobatanidzwa kune coaxial connectors vachishandisa screw type michina.Shandisa torque wrench kudzora kusimba.
2） Kushanda musimboti
Coaxial mitsara ine mamwe akakosha frequency ane hukama maitiro, ayo anotsanangura mashandisiro avo anogona kudzika kweganda uye kucheka-kuremara frequency.Kudzika kweganda kunotsanangura chiitiko chepamusoro frequency zviratidzo zvinopararira pamwe neiyo coaxial line.Kana yakakwira frequency, maerekitironi anowedzerawo kufamba akananga kune conductor pamusoro peiyo coaxial line.Ganda mhedzisiro inotungamira kune yakawedzera attenuation uye dielectric kudziyisa, zvichiita kuti kurasikirwa kwekupokana pamwe neiyo coaxial mutsara kuve kukuru.Kuti uderedze kurasikirwa kunokonzerwa nekugadzirwa kweganda, coaxial tambo ine dhayamita yakakura inogona kushandiswa.
Zviripachena, kuvandudza mashandiro eiyo coaxial tambo mhinduro inoyevedza, asi kuwedzera saizi yecoaxial tambo kunoderedza iyo yakanyanya frequency iyo coaxial tambo inogona kufambisa.Kana iyo wavelength yeEM simba ichipfuura iyo transverse electromagnetic (TEM) modhi uye yotanga "kubounce" ichitevedza coaxial mutsara kune inochinjika yemagetsi 11 modhi (TE11), iyo coaxial tambo yekucheka-kudzima frequency ichagadzirwa.Iyi nyowani frequency modhi inounza mamwe matambudziko.Sezvo iyo nyowani frequency modhi ichipararira nekumhanya kwakasiyana kubva kuTEM modhi, icharatidza nekukanganisa TEM modhi chiratidzo chinofambiswa kuburikidza neiyo coaxial tambo.
Kuti tigadzirise dambudziko iri, isu tinofanirwa kudzikisa saizi yecoaxial tambo uye kuwedzera kucheka-kubvisa frequency.Kune tambo dzekoaxial uye coaxial zvinongedzo zvinogona kusvika kune millimeter wave frequency - 1.85mm uye 1mm coaxial connectors.Izvo zvakakosha kucherechedza kuti kudzikisa saizi yemuviri kuti ienderane kune yakakwirira mafrequency kuchawedzera kurasikirwa kwecoaxial tambo uye kuderedza simba rekugadzirisa simba.Rimwe dambudziko mukugadzira zvinhu izvi zvidiki nderekunyatso kudzora ma mechanic tolerances kudzikisa akakosha emagetsi kukanganisa uye impedance shanduko pamutsara.Kune tambo dzine kunzwisiswa kwakanyanya, zvinodhura zvakanyanya kuita izvi.
