Cov lim dej RF thiab Microwavesiv los lim cov teeb liab tsis xav tau los ntawm kev nkag mus rau hauv lub cev. Nrog rau kev nce ntxiv ntawm cov qauv wireless hauv cov zaus uas twb muaj lawm, cov lim dej tam sim no ua lub luag haujlwm tseem ceeb heev thiab yuav tsum tau txo qis kev cuam tshuam. Lawv tau tsim los ua haujlwm ntawm cov zaus tshwj xeeb thiab tso cai / attenuator RF teeb liab ntawm ntau zaus sib txawv. RF Filters muaj ob hom zaus bands - passband thiab stopband. Cov teeb liab uas nyob hauv passband tuaj yeem hla dhau nrog qhov tsawg kawg nkaus attenuation thaum cov teeb liab uas nyob hauv stopband ntsib kev attenuation hnyav.
LimHom: Muaj ntau hom lim RF sib txawv - Cov Lim Band Pass, Cov Lim Low Pass, Cov Lim Band Stop, Cov Lim High Pass thiab lwm yam. Txhua hom ua haujlwm sib txawv.
Tshuab: Raws li daim ntawv thov thiab qhov loj ntawm lub wireless system muaj ntau hom lim - Notch Filters, SAW Filters, Cavity Filters, Waveguide Filters thiab lwm yam. Txhua tus muaj cov yam ntxwv sib txawv thiab cov qauv sib txawv.
Passband Zaus (MHz): Qhov no yog qhov ntau zaus uas cov teeb liab tuaj yeem hla dhau nrog qhov tsawg kawg nkaus attenuation.
Zaus ntawm qhov nres (MHz): Qhov no yog qhov zaus uas cov teeb liab raug txo qis. Qhov siab dua qhov kev txo qis zoo dua. Qhov no tseem hu ua kev cais tawm.
Kev Poob Ntxig (dB): Nws yog qhov poob uas tshwm sim thaum lub teeb liab taug kev hla qhov ntau zaus ntawm passband. Qhov qis dua qhov kev poob ntxig, qhov kev ua haujlwm ntawm lub lim dej zoo dua.
Kev Txo Qhov Nres (dB): Nws yog qhov kev txo qis uas cov teeb liab uas nyob hauv qhov nres ntawm ib lub lim dej muab. Qhov loj ntawm kev txo qis uas cov teeb liab ntsib tuaj yeem sib txawv raws li lawv qhov zaus.
Txhua yam RF tau teev cov lim dej RF los ntawm cov chaw tsim khoom ua lag luam hauv kev lag luam. Xaiv hom lim dej thiab tom qab ntawd siv cov cuab yeej tshawb nrhiav parametric xws li Zaus, Kev Ntxig, Hom Pob Khoom thiab Lub Hwj Chim kom nqaim cov lim dej raws li koj qhov xav tau. Rub tawm cov ntawv qhia txog cov ntaub ntawv thiab saib cov lus qhia ntawm cov khoom kom pom cov lim dej zoo rau koj daim ntawv thov.
Peb kuj tseem tuaj yeem kho cov khoom siv rf passive raws li koj xav tau. Koj tuaj yeem nkag mus rau nplooj ntawv kho kom raug kom muab cov lus qhia koj xav tau.
