A isihlungi se-band-passisebenza:
Isihlungi esifanelekile kufanele sibe nebhendi yokudlula eyisicaba ngokuphelele, isibonelo, akukho nzuzo kubhendi yokudlula noma ukuncipha kuwo wonke amafrikhwensi angaphandle kwebhendi yokudlula kuncipha ngokuphelele Ngaphezu kwalokho, ukuguqulwa kwebhendi yokudlula ebangeni elincane kakhulu lokuvama ukuze kuqedwe. Eqinisweni, asikho isihlungi se-band-pass esifanele. Isihlungi asikwazi ukulindela ukuthi wonke amafrikhwensi angaphandle kwebanga lefrikhwensi anciphe ngokuphelele, ikakhulukazi, kukhona ibhande okufanele incishiswe kodwa lingahlukanisiwe. Lokhu kuvame ukubizwa ngokuthi isenzeko sokuphuma kwesihlungi, kanye nokuncishiswa ku-dB ngeshumi leminyaka okumele limele. Ngokuvamile, idizayini yesihlungi izama ukuqinisekisa ukuthi i-rolloff inciphisa ububanzi bokusebenza okungcono kwalowo mklamo wesihlungi eduze. Kodwa-ke, njengoba uhla lwe-roll-off luba luncane futhi luncane, i-pass-band ayisekho isicaba - yaqala ukubonakala "i-ripple". Lesi simo sibonakala ikakhulukazi onqenqemeni lwe-passband, lo mphumela ubizwa ngokuthi i-Gibbs phenomenon.
Isihlungi se-cavity yisihlungi se-microwave esinesakhiwo se-resonant cavity. Imbobo ingalingana ne-inductance ehambisana ne-capacitor ukuze yakhe isiteji esizwakalayo ukuze kubonakale umsebenzi wokuhlunga we-microwave. Uma kuqhathaniswa nezinye izinhlobo zezihlungi ze-microwave, isihlungi se-cavity sinesakhiwo esiqinile, ukusebenza okuzinzile nokuthembekile, inani eliphakeme le-Q, ukukhishwa okuhle kokushisa, futhi i-passband yayo ye-parasitic ephezulu ikude. Ngakho-ke, ukuhlunga i-cavity kusetshenziswa eziteshini ezinkulu zokuxhumana. Ukusetshenziswa kwedivayisi kuvame kakhulu.
I-Sichuan Keenlion Microwave ingomunye wabahlinzeki bezingxenye ze-RF/Microwave. Imikhiqizo eyinhloko isihlukanisi samandla, isihlungi se-band pass, i-coupler, i-duplexer. Ngokukhethekile imikhiqizo elandelayo i-microstrip power divider, i-directional coupler, i-band pass filter, i-Hybrid Bridge, i-Microwave Isolator, i-Microwave Circulator, i-Passive Components VHF Duplexer, Combiner, njll. I-Sichuan Keenlion Microwave isiphenduke inkampani yesimanje ye-R & D yobuchwepheshe obuphezulu, ukukhiqiza, ukuthengisa nesevisi. Imikhiqizo isetshenziswa kakhulu kwi-inradio paging, ithelevishini yedijithali, uhlelo lokuxhumana lwe-microwave (GSM, 3G, Wimax, LTE), uhlelo lwe-radar kanye nemikhiqizo ehlukahlukene ye-RF syste.Sichuan Keenlion Microwave idayiswa emhlabeni wonke futhi yaziswa kakhulu. Njengomunye womkhiqizi nabathekelisi be-microwave abafayelile, isithunzi semakethe ye-Sichuan Keenlion Microwave, imigudu ebanzi yebhizinisi, isisekelo esiqinile samakhasimende kanye nokuncintisana okuqinile kwemakethe.
Singakwazi futhi ukwenza ngokwezifiso izingxenye ze-rf passive ngokuya ngezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
