Izihlungi ze-Low Pass RF Coaxial High Frequency Microstrip Microwave Millimeter Wave Radio Frequency Suspended Stripline Waveguide
Isihlungi se-RF low pass yisihlungi sokucubungula isignali esigcina amasignali amafrikhwensi aphansi ngokususa amasiginali aphezulu. Ivumela amasiginali anamafrikhwensi angaphansi komkhawulo othize ukuthi adlule, kodwa yenqaba amasiginali anamaza amakhulu kunalowo mkhawulo.
Izici zezihlungi zokudlula okuphansi kwerediyo:
1. Amasignali angaphansi kwefrikhwensi ethile kuphela avunyelwe ukudlula, kuyilapho amasignali angaphezu kwaleyo frequency ayahlungwa noma abe buthakathaka.
2. Uma udlula kumasignali we-low-frequency, cishe alukho ushintsho esigabeni.
3. Ngokuvamile, i-capacitor eyodwa noma ngaphezulu nama-inductors asetshenziselwa ukwakha izihlungi ze-telecom low pass.
Ukusetshenziswa kwezihlungi ze-coaxial low pass:
1.Isiginali ebushelelezi
Isihlungi se-high-frequency low pass sisetshenziswa kakhulu ukushelela isignali, singasusa umsindo kusiginali yefrikhwensi ephezulu, ukuze isiginali izinze kakhudlwana. Ezimeni lapho isignali ebushelelezi idingeka khona, isihlungi se-microstrip low pass singasusa umsindo wokuphazamiseka we-high-frequency, ngaleyo ndlela senze isistimu ithembeke futhi izinze.
2.Ukunciphisa umsindo
Isihlungi se-low pass ngeke sithinte isignali yefrikhwensi ephansi, kuyilapho sigcina isignali yefrikhwensi ephansi, umsindo we-high-frequency ungahlungwa. Ekucutshungulweni komsindo noma ekucubungulweni kwesithombe, izihlungi zokudlula kancane zingahlunga umsindo futhi zenze isignali ecutshunguliwe icace.
3.Yehlisa iphutha
Isihlungi sokudlula okuphansi singanciphisa iphutha, ikakhulukazi esilungele ukukalwa kwensimbi enembayo. Kwezinye izilinganiso ezinzima, isihlungi sokudlula okuphansi singasusa umsindo, ukuphazamiseka nezinye izici, ukuze imiphumela yokulinganisa inembe kakhulu futhi ithembeke.
4.Uhla olubanzi lohlelo lokusebenza
Isihlungi se-Millimeter wave low pass sinohlu olubanzi kakhulu lwezinhlelo zokusebenza, kusukela kumsindo kuya esithombeni, kusukela ekuxhumaneni kuya ekulawuleni, cishe yonke indawo. Isibonelo, ekucubunguleni isignali ye-baseband, isihlungi sokudlula esiphansi siyadingeka.
Ekuxhumaneni, isihlungi sephasi eliphansi esimisiwe singahluza umsindo wemvamisa ephezulu, ukuphazamiseka, njll., ukuze kuqinisekiswe ikhwalithi yokuxhumana; Emkhakheni wokulawula, isihlungi se-stripline low pass singasetshenziselwa ukushelela kwesignali nokuhlunga umsindo.
Qualwaveinikeza izihlungi ze-microwave low pass ebangeni le-DC-50GHz. Izihlungi ze-waveguide low pass zisetshenziswa kabanzi ezinhlelweni eziningi.
