RF High Stopband Rejection Me Me Telecom Low Pass Lim
Lub lim dej qis yog lub teeb liab ua cov lim dej uas khaws cov cim tsis tshua muaj los ntawm kev tshem tawm cov teeb liab siab. Nws tso cai rau cov teeb liab nrog ntau zaus tsawg dua li ib qho chaw pib dhau, tab sis tsis lees paub cov cim nrog ntau zaus ntau dua li qhov pib.
Nta:
1. Tsuas yog cov cim qhia hauv qab ib lub sijhawm tshwj xeeb raug tso cai hla dhau, thaum cov cim saum toj no tau lim lossis tsis muaj zog.
2. Thaum dhau los ntawm cov teeb liab tsawg zaus, yuav luag tsis muaj kev hloov pauv hauv theem.
3. Feem ntau, ib lossis ntau lub capacitors thiab inductors yog siv los tsim cov lim dej qis.
Daim ntawv thov:
1.Smooth teeb liab
low-pass lim feem ntau yog siv los ua kom lub teeb liab du, nws tuaj yeem tshem tawm lub suab nrov hauv lub teeb liab siab, kom lub teeb liab ua kom ruaj khov. Nyob rau hauv cov ntaub ntawv uas yuav tsum tau ib tug du teeb liab, lub low-pass lim yuav tshem tawm high-frequency interference suab, yog li ua rau lub system txhim khu kev qha thiab ruaj khov.
2. suab nrov txo
low-pass lim yuav tsis cuam tshuam rau lub teeb liab tsawg zaus, thaum khaws cov teeb liab tsawg zaus, lub suab nrov nrov tuaj yeem lim tawm. Hauv kev ua suab lossis kev ua cov duab, cov ntxaij lim dej qis dhau tuaj yeem lim tawm suab nrov thiab ua kom cov teeb liab ua tiav.
3. txo qhov yuam kev
low-pass lim tuaj yeem txo qhov yuam kev, tshwj xeeb tshaj yog haum rau kev ntsuas ntsuas ntsuas. Hauv qee qhov kev xav tau kev ntsuas, qhov ntsuas qis qis tuaj yeem tshem tawm cov suab nrov, cuam tshuam thiab lwm yam, kom qhov ntsuas ntsuas tau zoo dua thiab txhim khu kev qha.
4.ntau yam ntawm daim ntawv thov
Tsawg pass lim muaj ntau yam kev siv, los ntawm suab mus rau duab, los ntawm kev sib txuas lus mus rau kev tswj, yuav luag txhua qhov chaw. Piv txwv li, nyob rau hauv baseband teeb liab ua, ib tug low-pass lim yog tsim nyog.
Hauv kev sib txuas lus, cov lim dej qis tuaj yeem lim tawm cov suab nrov nrov, cuam tshuam, thiab lwm yam, kom ntseeg tau tias kev sib txuas lus zoo; Hauv kev tswj hwm, lub lim dej qis tuaj yeem siv rau kev teeb tsa kom du thiab suab nrov lim.
QualwaveCov khoom siv siab nres tsis lees txais cov ntxaij lim dej tsawg dhau hauv ntau zaus DC-50GHz. Cov lim dej qis dhau tau siv dav hauv ntau daim ntawv thov.
