Mafirita eRF neMicrowaveanoshandiswa kusefa masaini asingadiwe kuti asapinde musystem. Nekuwedzera kwemazinga ewireless muma frequency bands aripo, ma filters ikozvino anoita basa rakakosha uye anodiwa kuderedza kupindira. Akagadzirwa kuti ashande pama frequency chaiwo uye abvumire/attenuator RF signals pama frequency akasiyana. Ma RF filters ane mhando mbiri dzema frequency bands - passband ne stopband. Ma signals ari mu passband anogona kupfuura nepashoma asi ma signals ari mu stopband anonzwa attenuation yakakura.

SefaRudzi: Kune mhando dzakasiyana dzemafirita eRF - Mafirita eBand Pass, Mafirita eLow Pass, Mafirita eBand Stop, Mafirita eHigh Pass nezvimwewo. Rudzi rumwe nerumwe runoshanda nenzira yakasiyana.

Tekinoroji: Zvichienderana nezvinodiwa uye saizi yesystem yewaya isina waya, kune mhando dzakasiyana dzemafirita - Notch Filters, SAW Filters, Cavity Filters, Waveguide Filters nezvimwewo. Imwe neimwe ine hunhu hwakasiyana uye zvinhu zvakasiyana zvechimiro.

Kufamba kwePassband Frequency (MHz): Iyi ndiyo frequency range apo masaini anogona kupfuura nepaasina kudzikamisa zvakanyanya.

Kureba kweStopband (MHz): Iyi ndiyo frequency range apo masaini anodzikira. Kudzikira kwesimba kunowedzera zviri nani. Izvi zvinonziwo isolation.

Kurasikirwa Nekuiswa (dB): Kurasikirwa kunoitika kana chiratidzo chichifamba nepa passband frequency range. Kurasikirwa nekuisa kwakaderera kunoita kuti firita ishande zvakanaka.

Kudzikira kweStopband (dB): Kudzikira kwesimba kunoitika nezviratidzo zviri mustopband yefirita yakapihwa. Hukuru hwekudzikira kwesimba kunosangana nezviratidzo hunogona kusiyana zvichienderana nehuwandu hwazvo.

Zvese RF yakanyora maRF filters kubva kuvagadziri vanotungamira muindasitiri iyi. Sarudza rudzi rwefirita wobva washandisa maturusi ekutsvaga eparametric akadai seFrequency, Insertion Loss, Package Type uye Power kuti uderedze mafirita zvichienderana nezvaunoda. Dhawunirodha ma datasheets uye tarisa matsanangudzo echigadzirwa kuti uwane firita yakakodzera application yako.

Tinogonawo kugadzirisa zvikamu zveRF passive zvinoenderana nezvamunoda. Munogona kupinda papeji rekugadzirisa kuti mupe zvinodiwa zvamunoda.
