Jingxin Chaw tsim tshuaj paus ntawm RF isolators

An RF cais tawmyog ib tug passive ob-chaw nres nkoj ntaus ntawv feem ntau siv nyob rau hauv xov tooj cua zaus (RF) systems los muab kev rho tawm ntawm lub Cheebtsam los yog subsystems. Nws lub luag haujlwm tseem ceeb yog tso cai rau cov teeb liab hla mus rau hauv ib qho kev taw qhia thaum txo qis lossis thaiv cov teeb liab cuam tshuam los yog kis mus rau qhov sib txawv. RF isolator feem ntau muab tso rau ntawm ob lub cuab yeej lossis cov kab ke los tiv thaiv cov khoom rhiab los ntawm cov teeb meem tsis xav tau, txhim kho kev ua haujlwm, thiab tiv thaiv kev cuam tshuam.

Cov yam ntxwv tseem ceeb thiab cov yam ntxwv ntawm RF isolators suav nrog:

1. Kev rho tawm: RF cais tawm yog tsim los muab kev sib cais siab ntawm cov tswv yim thiab cov chaw nres nkoj. Kev rho tawm yog hais txog lub peev xwm ntawm tus neeg cais tawm los thaiv lossis txo qis lub teeb liab lub zog nyob rau hauv qhov kev taw qhia rov qab. Nws yog feem ntau teev nyob rau hauv decibels (dB) thiab sawv cev rau qhov piv ntawm lub hwj chim ntawm qhov chaw nres nkoj input thiab lub hwj chim ntawm qhov chaw nres nkoj cais.
2. Insertion Loss: Insertion poob yog hais txog tus nqi ntawm lub teeb liab lub zog uas ploj lawm thaum nws dhau los ntawm lub tshuab cais tawm. Qhov zoo tshaj plaws, ib qho kev sib cais yuav tsum muaj qhov tsawg kawg nkaus qhov poob kom ntseeg tau tias cov teeb liab kis tau zoo. Insertion poob yog teev nyob rau hauv decibels thiab sawv cev rau qhov piv ntawm lub hwj chim ntawm lub input chaw nres nkoj thiab lub hwj chim ntawm qhov chaw nres nkoj tso zis.
3. Rov Los Loss: Rov qab poob yog ib qho kev ntsuas ntawm tus nqi ntawm lub teeb liab lub zog rov qab los ntawm qhov chaw. Kev poob siab rov qab qhia tau tias zoo impedance txuam thiab qhov teeb meem tsawg heev. Nws tau teev nyob rau hauv decibels thiab sawv cev rau qhov sib piv ntawm lub zog ntawm lub teeb pom kev zoo thiab lub zog ntawm qhov teeb meem teeb meem.
4. Ntau zaus: RF cais tawm yog tsim los ua haujlwm nyob rau hauv qhov tshwj xeeb zaus. Qhov ntau zaus yog feem ntau teev nyob rau hauv cov nqe lus ntawm qhov tsawg kawg nkaus thiab siab tshaj plaws frequencies uas lub isolator muab kev pom zoo. Nws yog ib qho tseem ceeb uas yuav tau xaiv ib qho kev sib cais uas phim qhov ntau zaus ntawm cov phiaj xwm RF.
5. Lub Hwj Chim Muaj Peev Xwm Muaj Peev Xwm: RF cais tawm muaj nyob rau hauv ntau lub zog tuav lub peev xwm, xws li los ntawm cov ntawv thov hluav taws xob qis mus rau cov ntawv siv hluav taws xob siab. Lub peev xwm tuav lub zog qhia txog qib siab tshaj plaws uas lub tshuab cais tawm tuaj yeem ua haujlwm yam tsis muaj kev puas tsuaj lossis kev puas tsuaj.
6. VSWR (Voltage Standing Wave Ratio): VSWR yog ib qho kev ntsuas ntawm qhov tsis sib haum xeeb ntawm lub impedance ntawm lub isolator thiab impedance ntawm kev sib txuas RF system. VSWR qis qhia tau tias muaj kev sib txuam zoo, thaum lub siab VSWR qhia qhov tsis sib haum. Nws yog feem ntau teev raws li tus piv thiab sawv cev rau qhov piv ntawm qhov siab tshaj plaws voltage thiab qhov tsawg kawg nkaus voltage nyob rau hauv ib tug sawv yoj qauv.
7. Qhov kub thiab txias: RF cais tawm tau teev qhov kub thiab txias nyob rau hauv uas lawv tuaj yeem ua haujlwm tau zoo. Nws yog ib qho tseem ceeb uas yuav tau xav txog qhov ntsuas kub ntawm qhov kev sib cais kom ntseeg tau tias nws tuaj yeem tiv taus ib puag ncig ntawm daim ntawv thov.
8. Loj thiab Pob: RF cais tawm muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab pob hom, suav nrog cov pob khoom ntog thiab cov khoom sib txuas. Qhov loj thiab pob hom nyob ntawm seb qhov kev thov tshwj xeeb thiab cov qauv ntawm RF system.

Cov yam ntxwv thiab cov yam ntxwv no txiav txim siab qhov ua tau zoo thiab tsim nyog ntawm RF cais tawm rau ib daim ntawv thov. Nws yog ib qho tseem ceeb kom ua tib zoo xav txog cov xwm txheej no thaum xaiv ib qho kev sib cais kom ntseeg tau tias kev sib raug zoo nrog RF system thiab ua tiav qhov kev xav tau kev sib cais thiab cov yam ntxwv ntawm cov teeb liab.

Jingxin tsuas yog tsim thiab tsim covcoaxial caisrau cov kev daws teeb meem. Raws li cov lus tawm tswv yim, muaj qee tus neeg muag khoom zoo ntawm VHF, UHF thiab cov khoom siv hluav taws xob ntau zaus hauv peb cov npe khoom. Raws li tus tsim qauv kev cai, Jingxin tuaj yeem tshwj xeeb txiav ib qho raws li qhov xav tau. Cov lus nug tau txais tos: sales@cdjx-mw.com. ua tsaug ntau.
