Lim Dej Band Pass: Kev Hloov Pauv Tshiab rau Kev Lag Luam Hluav Taws Xob

Ua ib lub tuam txhab tsim khoom siv hluav taws xob, peb zoo siab los qhia txog kev tsim kho tshiab tshaj plaws hauv peb cov khoom - lub Lim dej hla (BPF). BPFs yog cov khoom siv hluav taws xob passive uas tau tsim los xaiv qee qhov zaus hla dhau, thaum thaiv lwm tus. Hauv tsab blog no, peb yuav tshawb nrhiav seb BPFs raug siv li cas hauv kev lag luam hluav taws xob los tsim cov khoom zoo dua thiab txhim kho kev ua tau zoo.

Dab tsi yog Band Pass Filter?

Lub lim dej Band Pass yog ib hom lim hluav taws xob uas tso cai rau ntau yam zaus kom dhau los ntawm nws lub voj voog. Lub lim no nquag tswj hwm txhua qhov zaus sib nrug ntawm qhov bandwidth xav tau, ua rau nws yog ib qho cuab yeej zoo rau kev ua cov teeb liab. Kev siv BPFs hauv Kev Lag Luam ElectronicsBPFs yog siv thoob plaws ntau yam kev lag luam, suav nrog kev sib txuas lus, suab thiab video, thiab cov khoom siv kho mob.

Nov yog cov ntawv thov tseem ceeb tshaj plaws ntawm BPFs hauv kev lag luam hluav taws xob.

Kev sib txuas lus wireless:Cov lim dej Band Pass feem ntau raug koom ua ke rau hauv cov kab ke sib txuas lus wireless, xws li xov tooj ntawm tes, kom tswj tau lub teeb liab ruaj khov. BPFs muaj txiaj ntsig zoo tshwj xeeb thaum nws los txog rau kev tswj cov teeb liab tawm ntawm band, uas tuaj yeem ua rau muaj kev cuam tshuam thiab txo qhov zoo ntawm lub teeb liab.

Suab thiab video:Cov lim dej Band Pass kuj tseem siv rau hauv cov tshuab suab kom tiv thaiv cov zaus tsis xav tau los ntawm kev hla dhau. Lawv ua rau muaj suab zoo tsis muaj suab nrov lossis kev cuam tshuam. Hauv kev tsim cov yeeb yaj kiab, BPFs tau dhau los ua qhov tsim nyog rau kev tsim cov duab HD. Lawv pab txhawb kev tshem tawm cov zaus tsis xav tau thiab harmonics thaum khaws cia qhov ntau yam xav tau.

Cov khoom siv kho mob:Cov BPFs tau dhau los ua cov khoom tseem ceeb hauv cov khoom siv kho mob xws li cov tshuab magnetic resonance imaging (MRI). Los ntawm kev tswj cov zaus sab nraud ntawm qhov xav tau, lawv tsim cov duab meej dua. Ib yam li ntawd, lawv siv rau hauv cov tshuab ntsuas ntshav los lim cov qe ntshav liab thiab dawb ntawm cov qauv.

Xaus lus, Band Pass Filters yog cov cuab yeej muaj zog uas tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob. Lawv lub peev xwm los tswj cov zaus tsis xav tau thiab txhim kho qhov sib piv ntawm lub teeb liab thiab suab nrov ua rau lawv muaj txiaj ntsig zoo rau ntau yam kev siv.

Ua ib lub tuam txhab tsim khoom siv hluav taws xob, peb muaj kev txaus siab rau kev siv cov thev naus laus zis no rau hauv peb cov khoom kom muab kev ua tau zoo tshaj plaws rau peb cov neeg siv khoom. Nws qhov tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov hluav taws xob ua rau Band Pass Filters yog ib qho tseem ceeb hauv kev lag luam hluav taws xob.

Si Chuan Keenlion Microwave Muaj ntau hom kev xaiv hauv narrowband thiab broadband configurations, npog cov zaus txij li 0.5 txog 50 GHz. Lawv tau tsim los tswj hwm los ntawm 10 txog 30 watts input zog hauv 50-ohm transmission system. Microstrip lossis stripline designs siv, thiab optimized rau kev ua tau zoo tshaj plaws.

Peb kuj tuaj yeem ua tau kho kom haum lub rf Band Pass Filter raws li koj xav tau. Koj tuaj yeem nkag mus rau nplooj ntawv kho kom haum rau koj kom muab cov lus qhia uas koj xav tau.
