Qhov kev ua tau zoo ntawm txoj kab nruj yog txiav txim siab los ntawm cov yam ntxwv ntawm nws cov khoom, xws li nws cov hluav taws xob conductivity, dielectric tas li, thiab inductance. Cov yam ntxwv no yog qhov tseem ceeb vim tias lawv cuam tshuam rau txoj kab sib kis txoj kev muaj peev xwm hloov cov cim ntawm ib qho mus rau lwm qhov yam tsis muaj kev cuam tshuam lossis cuam tshuam. Tsis tas li ntawd, kev teeb tsa lub cev ntawm cov kab sib kis kuj cuam tshuam rau nws qhov kev ua tau zoo, xws li tus naj npawb ntawm cov lem, qhov ntev ntawm txoj kab, thiab qhov sib nrug ntawm qhov lem.
Txoj kab nruj yog dab tsi?
Ib txoj kab nruj muaj ntau yam khoom, qhov chaw thiab khoom siv. Cov khoom tseem ceeb muaj xws li cov kab xaim hluav taws xob, cov khoom siv hluav taws xob, cov xaim hauv av, thiab cov ntaub thaiv hlau hlau.

Tus neeg xyuas pib yog cov khoom tseem ceeb ntawm cov kab nrib pleb thiab yog lub luag haujlwm rau nqa tam sim no. Nws feem ntau yog ua los ntawm tooj liab, txhuas lossis lwm yam khoom siv zoo heev. Tus neeg xyuas pib txoj kab uas hla thiab lub ntsuas hluav taws xob yuav tsum tau ua tib zoo xaiv los xyuas kom meej tias nws tuaj yeem muaj kev nyab xeeb xa mus rau qhov xav tau voltage thiab tam sim no.

Insulators yog siv los tswj cov hluav taws xob hauv nruab nrab ntawm tus neeg xyuas pib thiab cov xaim hauv av. Insulators feem ntau yog ua los ntawm ceramic, roj hmab, yas los yog lwm yam khoom siv tsis siv.

Cov xaim hauv av yog siv los muab txoj hauv kev rau qhov tam sim no ntws rov qab mus rau qhov chaw. Nws feem ntau yog ua los ntawm tooj liab, txhuas lossis lwm yam khoom siv zoo heev.

Cov ntaub thaiv npog hlau yog siv los tiv thaiv cov kab hluav taws xob sib kis los ntawm kev cuam tshuam electromagnetic. Nws feem ntau yog ua los ntawm txhuas lossis lwm yam khoom siv hlau uas muaj permeability siab.

Thaum xaiv cov khoom siv rau cov kab nrib pleb, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov kev khiav hauj lwm voltage thiab tam sim no, zaus, thiab qhov kub thiab txias. Tsis tas li ntawd, cov khoom yuav tsum raug xaiv los xyuas kom meej tias lawv sib haum nrog ib leeg, thiab cov kab sib kis tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob thiab cov khoom siv.
Muaj pes tsawg hom kab nrib pleb?
Muaj ob hom kab tsis sib xws: coaxial cables thiab waveguides. Coaxial cables feem ntau yog siv los nqa cov teeb liab hluav taws xob ntau zaus, thaum waveguide tsim los nqa hluav taws xob hluav taws xob ntawm xov tooj cua zaus. Qhov sib txawv tseem ceeb ntawm ob yog tias cov coaxial cables muaj ib tus neeg xyuas pib nyob ib puag ncig los ntawm tus neeg xyuas pib sab nraud, thaum lub waveguides muaj ib tus neeg xyuas pib nyob ib puag ncig los ntawm cov khoom siv dielectric, xws li iav lossis yas. Tsis tas li ntawd, waveguides feem ntau loj dua thiab tuaj yeem nqa lub zog siab dua li coaxial cables.
Yuav ua li cas xaiv txoj kab nruj zoo?
Thaum xaiv txoj kab nruj zoo tshaj plaws rau lub chaw nres tsheb xov tooj cua tshaj tawm, nws yog ib qho tseem ceeb uas yuav tau xav txog qib fais fab thiab zaus ntawm qhov chaw nres tsheb, hom kav hlau txais xov thiab ib puag ncig hauv zos. Tsis tas li ntawd, nws yog ib qho tseem ceeb los saib xyuas cov chaw tsim khoom cov lus qhia tshwj xeeb rau cov kab sib kis thiab cov khoom muaj kev lav phib xaub, nrog rau tag nrho cov nqi thiab kev xav txog kev teeb tsa.
Yuav ua li cas txuas txoj kab nruj hauv qhov chaw sib kis?
Txhawm rau txuas cov kab nruj hauv xov tooj cua hauv xov tooj cua, koj yuav tsum pib los ntawm kev ua kom cov kab sib kis tau zoo. Tom ntej no, koj yuav tsum txuas cov kab xa mus rau lub xov tooj cua chaw nres tsheb lub kav hlau txais xov. Koj yuav tsum tau kuaj xyuas kom paub tseeb tias cov kab sib raug zoo rau lub kav hlau txais xov. Thaum kawg, koj yuav tsum txuas cov kab sib txuas mus rau lub tshuab hluav taws xob thiab kho lub chaw nres tsheb xov tooj cua transmitter mus rau qhov tseeb zaus.
Dab tsi yog qhov tseem ceeb tshaj plaws ntawm txoj kab nruj?
Qhov tseem ceeb tshaj plaws lub cev thiab RF specifications ntawm ib tug nruj kab yog: impedance, hluav taws xob ntev, insertion poob, thiab rov qab poob. Lwm cov yam ntxwv los xav txog suav nrog qhov ntsuas kub coefficient, qhov kub thiab txias, kev khiav hauj lwm zaus, thiab qhov siab tshaj plaws voltage sawv yoj piv (VSWR).
Yuav ua li cas thiaj tswj tau txoj kab nruj hauv qhov chaw sib kis?
Txhawm rau ua kom zoo txhua hnub ntawm cov kab nruj hauv lub chaw nres tsheb hauv xov tooj cua raws li tus kws tshaj lij, koj yuav tsum pib los ntawm kev soj ntsuam cov kab nruj rau txhua qhov kev puas tsuaj, corrosion, lossis hnav. Koj yuav tsum tau xyuas kom meej tias tag nrho cov kev sib txuas yog nruj nruj thiab tag nrho cov clamps ruaj ntseg. Tom qab kuaj xyuas cov kab, koj yuav tsum xyuas cov kab xa mus rau txhua qhov kev hloov pauv ntawm cov hluav taws xob tsis zoo xws li lub zog nkag, VSWR, thiab rov qab poob. Thaum kawg, koj yuav tsum txheeb xyuas cov qauv ntawm cov kav hlau txais xov hluav taws xob kom ntseeg tau tias nws ua raws li qhov raug thiab ua haujlwm hauv cov lus qhia tshwj xeeb.
Yuav ua li cas kho ib txoj kab nruj yog tias nws tsis ua haujlwm?
1. Tshawb xyuas cov kab sib kis kom pom tias muaj kev puas tsuaj lossis hnav. Tshawb xyuas cov khoom tawg lossis xoob, cov xov hlau frayed, lossis khoov cov khoom txuas.

2. Hloov cov khoom tawg lossis hnav nrog cov tshiab. Xyuas kom tseeb tias cov khoom tshiab yog qhov loj thiab zoo tib yam li cov qub.

3. Ntxuav cov kab sib kis nrog lub degreaser thiab ib daim ntaub mos muag.

4. Rov ua cov kab sib txuas, xyuas kom txhua qhov chaw raug kaw kom ruaj ntseg.

5. Ntsuas cov kab sib kis kom paub tseeb tias nws ua haujlwm raug.

6. Yog tias cov kab sib txuas tsis ua haujlwm, xyuas seb puas muaj teeb meem ntxiv xws li cov pa tawm los yog luv luv hauv kab. Hloov cov khoom ntxiv raws li qhov tsim nyog.
Hom kev txuas twg yog siv rau txoj kab nruj?
Hom kev sib txuas siv rau cov kab sib kis tsis zoo suav nrog crimp-on thiab soldered connectors. Crimp-on connectors feem ntau yog tsim los ntawm tooj liab lossis txhuas thiab yuav tsum tau siv lub cuab yeej crimping los nias lub connector mus rau kab. Soldered connectors feem ntau yog ua los ntawm tooj liab los yog tin thiab yuav tsum tau ib tug soldering hlau thiab solder los txuas lub connector rau kab. Muaj ntau ntau hom crimp-on thiab soldered connectors muaj, xws li compression connectors, twist-on connectors, spade lugs, thiab taub qab connectors. Txhua hom muaj nws tus kheej qhov zoo thiab qhov tsis zoo. Tus naj npawb ntawm txhua hom kev sib txuas yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau.
