SMA connector yog ib tug dav siv semi precision subminiature RF thiab microwave connector, tshwj xeeb tshaj yog haum rau RF kev twb kev txuas nyob rau hauv hluav taws xob systems nrog frequencies mus txog 18 GHz los yog ntau dua.SMA connectors muaj ntau hom, txiv neej, poj niam, ncaj, txoj cai lub kaum sab xis, diaphragm fittings, thiab lwm yam., uas tuaj yeem ua tau raws li qhov yuav tsum tau ua.Nws qhov loj me me kuj tso cai rau nws siv, txawm tias hauv cov khoom siv hluav taws xob me me.
1, Taw qhia rau SMA connector
SMA feem ntau yog siv los muab RF kev sib txuas ntawm cov laug cam.Ntau lub tshuab microwave muaj xws li lim, attenuators, mixers thiab oscillators.Lub connector muaj ib tug threaded sab nraud kev twb kev txuas interface, uas muaj ib tug hexagon puab thiab yuav tsum tau nruj nrog ib tug ciaj ntswj.Lawv tuaj yeem raug kaw kom nruj kom raug siv qhov tshwj xeeb torque ciaj ntswj, kom qhov kev sib txuas zoo tuaj yeem ua tiav yam tsis tas yuav nruj dua.
Thawj SMA connector yog tsim los rau 141 semi-rigid coaxial cable.Tus thawj SMA connector tuaj yeem raug hu ua qhov sib txuas me tshaj plaws, vim tias qhov chaw nruab nrab ntawm cov coaxial cable tsim lub hauv paus tus pin ntawm kev sib txuas, thiab tsis tas yuav hloov pauv ntawm tus neeg xyuas pib coaxial thiab lub nruab nrab tus pin ntawm qhov tshwj xeeb txuas.
Nws qhov zoo dua yog tias cable dielectric txuas ncaj qha mus rau qhov sib txuas tsis muaj qhov sib txawv ntawm huab cua, thiab nws qhov tsis zoo yog tias tsuas yog qee qhov kev sib txuas / kev sib txuas tsis sib xws tuaj yeem nqa tawm.Txawm li cas los xij, rau cov ntawv thov siv cov kab hluav taws xob semi-rigid coaxial, qhov no yuav tsis zoo li qhov teeb meem, vim tias qhov kev teeb tsa feem ntau yog kho tom qab pib sib dhos.
2, Kev ua tau zoo ntawm SMA connector
SMA connector yog tsim los kom muaj qhov impedance tas li ntawm 50 ohms ntawm lub connector.SMA connectors tau tsim thiab tsim los rau kev ua haujlwm txog 18 GHz, txawm hais tias qee cov qauv muaj qhov zaus ntawm 12.4 GHz thiab qee cov qauv tau raug xaiv los ua 24 lossis 26.5 GHz.Cov kev txwv siab dua tuaj yeem xav tau kev ua haujlwm nrog kev rov qab poob ntau dua.
Feem ntau, SMA connectors muaj qhov xav tau siab dua li lwm cov khoom txuas mus txog 24 GHz.Qhov no yog vim qhov nyuaj ntawm kev kho cov kev txhawb nqa dielectric kom raug, tab sis txawm tias qhov nyuaj no, qee cov tuam ntxhab tau tswj kom kov yeej qhov teeb meem no tau zoo thiab muaj peev xwm xaiv lawv cov khoom sib txuas rau 26.5GHz kev ua haujlwm.
Rau cov cables hloov tau yooj yim, qhov txwv zaus feem ntau yog txiav txim siab los ntawm cov cable es tsis yog qhov txuas.Qhov no yog vim SMA connectors txais cov cables me me, thiab lawv cov kev poob yog ib txwm muaj ntau dua li cov khoom sib txuas, tshwj xeeb tshaj yog nyob rau zaus lawv siv tau.
3, Rated zog ntawm SMA connector
Qee qhov xwm txheej, qhov ntsuas ntawm SMA connector yuav yog qhov tseem ceeb.Qhov tseem ceeb parameter los txiav txim qhov nruab nrab lub zog tuav lub peev xwm ntawm mating ncej connector yog tias nws muaj peev xwm kis tau siab tam sim no thiab ua kom lub tshav kub nce mus rau ib tug nruab nrab kub.
Cov nyhuv cua sov feem ntau yog tshwm sim los ntawm kev tiv thaiv kev tiv thaiv, uas yog ib qho kev ua haujlwm ntawm qhov chaw sib tiv tauj thiab txoj kev sib txuas ntawm cov ntaub qhwv ua ke.Ib cheeb tsam tseem ceeb yog qhov chaw sib cuag, uas yuav tsum tau tsim kom zoo thiab haum zoo ua ke.Nws kuj tseem yuav tsum tau muab sau tseg tias qhov nruab nrab ntsuas lub zog txo qis nrog zaus vim tias qhov tsis kam tiv thaiv nce nrog zaus.
Lub zog ua cov ntaub ntawv ntawm SMA connectors sib txawv heev ntawm cov tuam txhab, tab sis qee cov duab qhia tau hais tias qee tus tuaj yeem ua 500 watts ntawm 1GHz thiab poob rau me ntsis tsawg dua 200 watts ntawm 10GHz.Txawm li cas los xij, qhov no kuj yog cov ntaub ntawv ntsuas, uas tej zaum yuav siab dua.
Rau SMA microstrip connector muaj plaub hom: detachable hom, hlau TTW hom, Medium TTW hom, ncaj qha txuas hom.Thov nias rau:https://www.dbdesignmw.com/microstrip-connector-selection-table/xaiv qhov kev yuav khoom.
