Cov Lim Dej Qis Dhau RF Coaxial High Frequency Microstrip Microwave Millimeter Wave Radio Frequency Suspended Stripline Waveguide
RF low pass filter yog lub lim dej ua haujlwm teeb liab uas khaws cov teeb liab zaus qis los ntawm kev tshem tawm cov teeb liab zaus siab. Nws tso cai rau cov teeb liab nrog zaus tsawg dua qhov txwv kom dhau, tab sis tsis lees txais cov teeb liab nrog zaus ntau dua qhov txwv ntawd.
Cov yam ntxwv ntawm cov lim dej tsawg zaus hauv xov tooj cua:
1. Tsuas yog cov teeb liab qis dua ib qho zaus tshwj xeeb thiaj li raug tso cai hla dhau, thaum cov teeb liab siab dua ntawd raug lim lossis qaug zog.
2. Thaum dhau los ntawm cov teeb liab qis 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 qis hauv telecom.
Daim ntawv thov ntawm coaxial qis dhau cov ntxaij lim dej:
1. Lub teeb liab du
Cov lim dej qis zaus siab feem ntau yog siv los ua kom lub teeb liab du, nws tuaj yeem tshem tawm lub suab nrov hauv lub teeb liab zaus siab, kom lub teeb liab ruaj khov dua. Hauv cov xwm txheej uas xav tau lub teeb liab du, lub lim dej qis microstrip tuaj yeem tshem tawm lub suab nrov cuam tshuam zaus siab, yog li ua rau lub kaw lus txhim khu kev qha thiab ruaj khov dua.
2. Txo suab nrov
Cov lim dej qis dhau yuav tsis cuam tshuam rau lub teeb liab qis, thaum khaws cov teeb liab qis, suab nrov siab tuaj yeem lim tawm. Hauv kev ua suab lossis kev ua duab, cov lim dej qis dhau tuaj yeem lim tawm suab nrov thiab ua rau cov teeb liab ua tiav meej dua.
3. Txo qhov yuam kev
Cov lim dej qis dhau tuaj yeem txo qhov yuam kev, tshwj xeeb tshaj yog haum rau kev ntsuas cov cuab yeej precision. Hauv qee qhov kev ntsuas uas nyuaj, cov lim dej qis dhau tuaj yeem tshem tawm suab nrov, kev cuam tshuam thiab lwm yam, yog li cov txiaj ntsig ntsuas tau raug dua thiab txhim khu kev qha.
4. Ntau yam ntawm daim ntawv thov
Cov lim dej millimeter wave low pass muaj ntau yam kev siv, los ntawm lub suab mus rau duab, los ntawm kev sib txuas lus mus rau kev tswj hwm, yuav luag txhua qhov chaw. Piv txwv li, hauv kev ua cov teeb liab baseband, cov lim dej me me yog qhov tsim nyog.
Hauv kev sib txuas lus, lub lim dej qis qis uas raug tshem tawm tuaj yeem lim tawm cov suab nrov siab, kev cuam tshuam, thiab lwm yam, kom ntseeg tau tias kev sib txuas lus zoo; Hauv kev tswj hwm, lub lim dej qis qis stripline tuaj yeem siv rau kev ua kom du thiab lim suab nrov.
Qualwavemuab cov lim dej microwave qis dhau hauv qhov ntau zaus DC-50GHz. Cov lim dej qis dhau waveguide siv dav hauv ntau daim ntawv thov.
