Cov Lim Dej Tsis lees txais Band RF Coaxial Comb Interdigital Microstrip Microwave Millimeter Wave Radio Frequency Spiral Suspended Stripline
Lim tsis lees txais Band
Lub lim dej tsis lees txais cov kab (band reject filter) yog ib lub lim dej siv rau hauv kev ua cov teeb liab kom txo qhov loj ntawm cov teeb liab hauv ib qho zaus tshwj xeeb thaum tso cai rau cov teeb liab hauv lwm qhov zaus dhau mus. Lub hauv paus ntsiab lus ua haujlwm ntawm lub lim dej tsis lees txais cov kab (band reject filter) yog los tshuaj xyuas cov teeb liab nkag hauv thaj chaw zaus, thiab xaiv qhov loj ntawm cov teeb liab raws li qhov zaus tshwj xeeb, kom ua tiav kev txo suab nrov ntawm qhov zaus tshwj xeeb.
Cov lim dej tsis lees txais cov hlua khi kuj tseem muab faib ua cov lim dej comb band reject, interdigital band reject filters, spiral band reject filters, thiab suspended stripline band reject filters.
Cov yam ntxwv tseem ceeb ntawm cov lim dej millimeter wave band reject:
1. Thaiv kev xa cov teeb liab hauv ib qho zaus tshwj xeeb: lub lim dej nres tsis muaj kev hloov pauv ntawm xoom, tab sis muaj qhov tsawg kawg nkaus ntawm kev hloov pauv ntawm qhov zaus txiav nruab nrab. Yog li ntawd, nws tuaj yeem thaiv kev xa cov teeb liab los ntawm nws qhov zaus nruab nrab.
2. Tso cai rau lwm cov teeb liab zaus kom dhau: Ntxiv rau qhov nruab nrab zaus, lub lim dej nres-stop tso cai rau cov teeb liab ntawm txhua lwm zaus kom dhau. Qhov no tso cai rau cov lim dej nres-stop siv los tshem tawm suab nrov, cuam tshuam thiab ua tau raws li cov kev cai teb zaus tshwj xeeb.
3. Kev cuam tshuam nthwv dej me me: piv rau lwm hom lim dej, cov lim dej band-stop muaj kev cuam tshuam nthwv dej me dua. Qhov no txhais tau tias nws tuaj yeem khaws cov duab thiab qhov loj ntawm lub teeb liab hla lub lim dej zoo dua.
4. Kev ua cov teeb liab Broadband: Lub lim dej band-stop siv tau rau kev ua cov teeb liab broadband, vim nws tuaj yeem khaws feem ntau ntawm cov khoom zaus thiab tsuas yog thaiv ib qho zaus tshwj xeeb.
5. Kev teb theem: Kev teb theem ntawm lub lim dej band-stop nyob ntawm nws txoj kev tsim thiab kev siv, tab sis feem ntau yog nyob nruab nrab ntawm lub lim dej qis-pass thiab lub lim dej siab-pass.
Daim ntawv thov ntawm microstrip band tsis lees txais cov lim dej:
1. Kev ua cov teeb liab hluav taws xob: Cov lim dej RF band tsis lees txais tuaj yeem siv los lim tawm qee qhov zaus cuam tshuam hauv kev ua cov teeb liab hluav taws xob, yog li txhim kho qhov zoo ntawm cov teeb liab.
2. Kev sib txuas lus hauv xov tooj cua: Hauv kev sib txuas lus hauv xov tooj cua, cov lim dej tsis lees txais 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 zaus siab: Cov lim dej nres siv tau los kho qhov teb zaus hauv cov voj voog kom ua tiav qhov kev ua haujlwm ntawm lub voj voog.
4. Cov khoom siv kho mob: Cov lim dej coaxial band reject siv tau rau hauv cov khoom siv kho mob, xws li cov cuab yeej electrocardiogram, los lim cov zaus los ntawm cov leeg thiab lwm yam kev cuam tshuam sab nraud.
Qualwavemuab cov lim dej tsis lees txais cov kab ke tsis lees txais uas muaj qhov nres siab hauv qhov zaus DC-40GHz. Cov lim dej tsis lees txais microwave band siv dav hauv ntau daim ntawv thov.
