A lim dej bandpassua haujlwm:
Ib lub lim zoo tagnrho yuav tsum muaj ib txoj kab hla tiaj tiaj, piv txwv li, tsis muaj qhov nce hauv txoj kab hla lossis kev txo qis ntawm txhua qhov zaus sab nraum txoj kab hla yog qhov txo qis tag nrho. Ntxiv rau, kev hloov pauv ntawm txoj kab hla hauv qhov ntau zaus me me kom ua tiav. Qhov tseeb, tsis muaj lub lim band-pass zoo tagnrho. Lub lim tsis tuaj yeem cia siab tias txhua qhov zaus sab nraum qhov ntau zaus yuav txo qis tag nrho, tshwj xeeb, muaj ib txoj kab uas yuav tsum tau txo qis tab sis tsis yog qhov sib cais. Qhov no feem ntau hu ua qhov xwm txheej ntawm lub lim dov tawm, thiab kev txo qis hauv dB ib xyoo caum los sawv cev. Feem ntau, tus qauv lim sim ua kom ntseeg tau tias qhov kev dov tawm nqaim qhov ntau thiab tsawg ntawm kev ua tau zoo dua ntawm kev tsim lim zoo li no. Txawm li cas los xij, nrog rau qhov ntau ntawm kev dov tawm tau me dua thiab me dua, txoj kab hla tsis tiaj tus lawm - pib tshwm sim rau "ripple". Qhov xwm txheej no pom tseeb tshwj xeeb hauv ntug kab hla, qhov cuam tshuam no hu ua qhov xwm txheej Gibbs.
Lub lim dej yog lub lim dej microwave nrog lub qauv resonant cavity. Lub cavity tuaj yeem sib npaug rau qhov inductance ua ke nrog lub capacitor los tsim ib theem resonant kom paub txog lub microwave filtering function. Piv nrog rau lwm hom microwave filters, lub lim dej muaj lub qauv ruaj khov, kev ua haujlwm ruaj khov thiab txhim khu kev qha, tus nqi Q siab, cua sov zoo dissipation, thiab nws cov high-end parasitic passband nyob deb. Yog li ntawd, cavity filtering yog siv rau hauv cov chaw sib txuas lus loj. Daim ntawv thov ntawm lub cuab yeej yog qhov ntau heev.
