A band-pass filterisebenza:

Isihluzi esifanelekileyo kufuneka sibe nebhendi yokupasa ethe tyaba ngokupheleleyo, umzekelo, akukho nzuzo kwibhendi yokupasa okanye ukuthomalalisa kuzo zonke iifrikhwensi ezingaphandle kwebhendi yokupasa ithomalalisa ngokupheleleyo Ukongeza, ukuguqulwa kwebhendi yokupasa kuluhlu oluncinci lwamaza ukugqibezela. Ngapha koko, akukho sihluzo sifanelekileyo sokupasa ibhendi. Isihluzi asikwazi ukulindela zonke iifrikhwensi ezingaphandle koluhlu lwamaza zithobe ngokupheleleyo, ngakumbi, kukho ibhendi eza kuthotywa kodwa ingeyiyo yodwa uluhlu. Oku ngokuqhelekileyo kubhekiselwa kuko njengesenzeko sokuqengqeleka kokucoca, kunye nokuthomalalisa kwi-dB ngeshumi leminyaka ukumela. Ngokwesiqhelo, uyilo lokucoca luzama ukuqinisekisa ukuba ukuqengqeleka kucutha umda womsebenzi ongcono woyilo lwesihluzi ngokusondeleyo. Nangona kunjalo, kunye noluhlu lwe-roll-off luba luncinci kwaye luncinci, i-pass-band ayisekho i-flat - yaqala ukubonakala "i-ripple". Le nto ibonakala ngokukodwa kwi-passband edge, esi siphumo sibizwa ngokuba yi-Gibbs phenomenon.

Isihluzi seCavity

Isihluzo somgodi sisihluzo se-microwave esinesakhiwo sombhobho ovakalayo. Umgodi unokulingana ne-inductance ngokuhambelana ne-capacitor ukwenza inqanaba elivakalayo ukuqonda umsebenzi wokucoca i-microwave. Xa kuthelekiswa nezinye iintlobo ze-microwave filters, i-cavity filter inesakhiwo esiqinileyo, esizinzileyo kunye nokusebenza okuthembekileyo, ixabiso eliphezulu le-Q, ukuchithwa kakuhle kobushushu, kunye ne-pasband yayo ephezulu ye-parasitic ikude. Ke ngoko, ukuhluzwa kwecango kusetyenziswa kwizikhululo eziphambili zonxibelelwano. Ukusetyenziswa kwesixhobo kuxhaphake kakhulu.

I-Sichuan Keenlion Microwave ngomnye wababoneleli be-RF/Microwave. Iimveliso eziphambili zesahluli samandla, isihluzo sokudlula ibhendi, i-coupler, i-duplexer. Ngokukodwa ezi mveliso zilandelayo ziyi-microstrip power divider, i-directional coupler, i-band pass filter, i-Hybrid Bridge, i-Microwave Isolator, i-Microwave Circulator, i-Passive Components i-VHF Duplexer, i-Combiner, njl. I-Sichuan Keenlion Microwave iye yaba yi-R & D ye-high-tech, imveliso, ukuthengisa kunye nenkampani yenkonzo. Iimveliso zisetyenziswa ngokubanzi kwi-inradio paging, umabonakude wedijithali, inkqubo yonxibelelwano lwe-microwave (GSM, 3G, Wimax, LTE), inkqubo ye-radar kunye neemveliso ezahlukeneyo zeRF syste.Sichuan Keenlion Microwave zithengiswa kwihlabathi liphela kwaye ziyaxatyiswa. Njengomnye wabavelisi kunye nabathumeli ngaphandle kwe-microwave efakiweyo, iSichuan Keenlion Microwave isandi semarike yodumo, amajelo oshishino abanzi, isiseko esiluqilima sabathengi kunye nokhuphiswano oluluqilima lwemarike.

Sisenokwenza ngokwezifiso amalungu e-rf passive ngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
