Izihlungi Zokwenqaba Ibhendi I-RF Coaxial Comb I-Interdigital Microstrip I-Microwave I-Millimeter Wave Radio Frequency Spiral Suspended Stripline
Isihlungi Sokwenqaba Ibhendi
I-Band Reject Filter iyisihlungi esisetshenziswa ekucubungulweni kwesignali ukucindezela ubukhulu besignali ngaphakathi kwebanga elithile lemvamisa ngenkathi ivumela amasignali kwamanye amabanga emvamisa ukuthi adlule. Umgomo osebenzayo wesihlungi se-band reject ukuhlaziya isignali yokufaka kusizinda semvamisa, nokucindezela ngokukhetha ubukhulu besignali ngokuya ngebanga lemvamisa elicacisiwe, ukuze kufezwe ukunciphisa umsindo kumvamisa ecacisiwe.
Izihlungi zokungafunwa kwebhendi zihlukaniswe kabanzi ngezihlungi zokungafunwa kwebhendi yekamu, izihlungi zokungafunwa kwebhendi yedijithali, izihlungi zokungafunwa kwebhendi yespiral, izihlungi zokungafunwa kwebhendi yestripline emisiwe.
Lokhu okulandelayo yizihlungi ze-millimeter wave band reject izici eziyinhloko:
1. Ukudluliswa kwesignali ye-block kububanzi obuthile bemvamisa: isihlungi se-band-stop asinawo umsebenzi wokudlulisa ongu-zero, kodwa sinomsebenzi wokudlulisa okungenani ku-center cutoff frequency. Ngakho-ke, singavimba ukudluliswa kwesignali ngebanga layo lemvamisa ephakathi.
2.Vumela ezinye izimpawu zemvamisa ukuthi zidlule: Ngaphezu kobubanzi bemvamisa ephakathi, isihlungi se-band-stop sivumela izimpawu zazo zonke ezinye imvamisa ukuthi zidlule. Lokhu kuvumela izihlungi ze-band-stop ukuthi zisetshenziswe ukususa umsindo, ukuphazamiseka nokuhlangabezana nezidingo ezithile zokuphendula imvamisa.
3. Ukuphambuka kwamagagasi amancane: uma kuqhathaniswa nezinye izinhlobo zezihlungi, izihlungi ze-band-stop zinokuphambuka kwamagagasi okuncane. Lokhu kusho ukuthi kungalondoloza kangcono ukuma kanye nobukhulu besiginali esidlula kusihlungi.
4. Ukucutshungulwa kwesignali ye-Broadband: Isihlungi se-band-stop singasetshenziswa ekucutshungulweni kwesignali ye-broadband, ngoba singagcina iningi lezingxenye zemvamisa futhi sivimbele kuphela ububanzi bemvamisa ethile.
5. Impendulo yesigaba: Impendulo yesigaba sesihlungi se-band-stop incike ekwakhiweni nasekusetshenzisweni kwaso, kodwa ngokuvamile iphakathi kwesihlungi esiphansi nesihlungi esiphezulu.
Ukusetshenziswa kwezihlungi ze-microstrip band reject:
1. Ukucubungula isignali kagesi: Izihlungi ze-RF band reject zingasetshenziswa ukuhlunga amaza athile okuphazamiseka ekucutshungulweni kwesignali kagesi, ngaleyo ndlela kuthuthukiswe ikhwalithi yesignali.
2. Ukuxhumana ngomsakazo: Ekuxhumaneni ngomsakazo, izihlungi zokulahla amaza omsakazo zingasetshenziswa ukuhlunga amaza angadingekile ezimpawini, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuxhumana.
3. Ama-elekthronikhi avame kakhulu: Izihlungi zebhendi zingasetshenziswa ukulungisa impendulo yemvamisa kumasekethe ukuze kufezwe ukusebenza kwesekethe okudingekayo.
4. Imishini yezokwelapha: Izihlungi ze-Coaxial band reject zingasetshenziswa emishini yezokwelapha, njengezinsimbi ze-electrocardiogram, ukuhlunga amaza avela emisipheni kanye neminye imithombo yokuphazamiseka kwangaphandle.
I-Qualwaveinikeza izihlungi zokwenqaba ibhendi yokuyeka eziphezulu ebangeni lemvamisa le-DC-40GHz. Izihlungi zokwenqaba ibhendi ye-microwave zisetshenziswa kabanzi ezinhlelweni eziningi zokusebenza.
