Dab tsi yog passive intermodulation (PIM)?

Thaum cov phiajcim no sib cuam tshuam nyob rau hauv cov kev sib tham tsis huv, lawv tuaj yeem tsim cov khoom siv tsis tau muaj ntau yam uas paub tias yog cov khoom lag luam intermodulation. Cov khoom no tuaj yeem cuam tshuam nrog thawj cov cim thiab ua rau distortion lossis kev poob qis hauv qhov kev ua haujlwm tag nrho.

Pim feem ntau tau ntsib hauv lub tshuab sib txuas lus wireless, tshwj xeeb tshaj yog nyob rau hauv lub high-fais fab ib puag ncig zoo li cov yees txawb lossis chaw nres tsheb. Nws tuaj yeem ua rau muaj teeb meem teeb meem, txo lub peev xwm network, thiab cov nqi hloov pauv cov ntaub ntawv txo qis.

Txhawm rau txo qis kev sib txuas lus, nws yog qhov tseem ceeb kom siv cov khoom siv zoo, tsim qauv zoo thiab tswj cov kab ke, thiab txo cov peev txheej ntawm kev cuam tshuam. Kev ntsuas kev tu ncua thiab kev ua ntu zus PIM kuj tau pom zoo kom ntseeg tau tias kev ua tau zoo tshaj plaws.
