RF High Stopband Rejection Me Me Telecom Band Reject Filters
Band Reject Filter
Band Reject Filter yog lub lim siv hauv kev ua cov teeb liab txhawm rau txhawm rau qhov loj ntawm lub teeb liab nyob rau hauv ib qho tshwj xeeb ntau zaus thaum tso cai rau cov teeb liab hauv lwm qhov ntau zaus dhau.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm band tsis kam lim yog txhawm rau txheeb xyuas cov teeb liab tawm tswv yim hauv qhov zaus, thiab xaiv qhov amplitude ntawm lub teeb liab raws li qhov ntau zaus, thiaj li ua tiav lub suab nrov txo ntawm qhov ntau zaus.
Cov hauv qab no yog nws cov yam ntxwv tseem ceeb:
1.Block teeb liab kis tau tus mob nyob rau hauv ib tug ntau zaus: lub band-nres lim tsis muaj kev hloov mus rau xoom, tab sis muaj ib tug hloov mus ua hauj lwm yam tsawg kawg nkaus ntawm qhov chaw txiav tawm zaus.Yog li ntawd, nws tuaj yeem thaiv kev sib kis ntawm cov teeb liab los ntawm nws qhov nruab nrab zaus ntau.
2.Cia lwm cov cim zaus kom dhau: Ntxiv rau qhov chaw ntau zaus, lub lim nres band tso cai rau cov cim ntawm tag nrho lwm zaus kom dhau.Qhov no tso cai rau band-stop lim siv los tshem tawm suab nrov, cuam tshuam thiab ua tau raws li cov lus teb tshwj xeeb.
3.Small yoj distortion: piv nrog rau lwm hom lim, band-stop lim muaj me yoj distortion.Qhov no txhais tau hais tias nws tuaj yeem khaws cia zoo dua cov duab thiab amplitude ntawm lub teeb liab hla lub lim.
4.Broadband teeb liab ua: Band-nres lim yuav siv tau rau kev ua cov broadband signals, vim hais tias nws muaj peev xwm khaws tau feem ntau ntawm cov zaus Cheebtsam thiab tsuas thaiv ib tug ntau zaus.
5. Theem teb: Cov lus teb theem ntawm lub lim nres band yog nyob ntawm nws tus qauv tsim thiab kev siv, tab sis feem ntau yog nruab nrab ntawm cov lim dej qis thiab cov lim dej siab.
Daim ntawv thov:
1. Kev ua cov teeb liab hluav taws xob: Band nres lim tuaj yeem siv los lim tawm qee qhov cuam tshuam ntau zaus hauv kev ua hluav taws xob teeb liab, yog li txhim kho cov teeb liab zoo.
2. Kev sib txuas lus hauv xov tooj cua: Hauv kev sib txuas lus hauv xov tooj cua, band nres lim tuaj yeem siv los lim tawm cov zaus tsis tsim nyog hauv cov teeb liab, yog li txhim kho kev sib txuas lus zoo.
3. Cov khoom siv hluav taws xob ntau zaus: Band nres lim tuaj yeem siv los kho cov lus teb zaus hauv circuits kom ua tiav qhov kev ua haujlwm hauv Circuit Court.
4. Cov khoom siv kho mob: Band nres lim tuaj yeem siv rau hauv cov khoom siv kho mob, xws li cov cuab yeej electrocardiogram, txhawm rau lim tawm cov zaus ntawm cov leeg thiab lwm qhov cuam tshuam sab nraud.
Qualwavekhoom siv siab nres band tsis lees txais band tsis lees txais cov lim dej hauv ntau zaus DC-18GHz.Cov band tsis lees txais cov ntxaij lim dej tau siv dav hauv ntau daim ntawv thov.
