I-Band Reject Filters RF Coaxial Comb Interdigital Microstrip Microwave Millimeter Wave Radio Frequency Spiral Suspended Stripline
Isihlungi Senqaba Ibhendi
I-Band Reject Filter yisihlungi esisetshenziswa ekucubunguleni isignali ukucindezela ubukhulu besignali phakathi kwebanga elithile lefrikhwensi kuyilapho ivumela amasignali kwamanye amafrikhwensi ukuthi adlule. Umgomo wokusebenza wesihlungi sokunqatshelwa kwebhendi ukuhlaziya isignali yokufaka kusizinda samafrikhwensi, futhi ngokukhetha ucindezela i-amplitude yesiginali ngokuya ngebanga lefrikhwensi eshiwo, ukuze kuzuzwe ukuncishiswa komsindo kumafrikhwensi ashiwo.
Izihlungi zokulahlwa kwebhendi ziphinde zihlukaniswe zibe izihlungi zokulahla ibhande le-comb, izihlungi zokulahla ibhande le-interdigital, izihlungi zokulahla i-spiral band, izihlungi ezimisiwe ze-stripline zokulahla.
Okulandelayo yizihlungi ze-millimeter wave zenqaba izici eziyinhloko:
1.Vimba ukudluliswa kwesignali ebangeni elithile lefrikhwensi: isihlungi sokumisa ibhande asinawo umsebenzi wokudlulisa onguziro, kodwa sinomsebenzi wokudlulisa obuncane endaweni yokunqamuka okumaphakathi. Ngakho-ke, ingavimbela ukudluliswa kwamasignali ngokusebenzisa ububanzi bayo obuphakathi.
2.Vumela amanye amasiginali wefrikhwensi ukuthi adlule: Ngokungeziwe kububanzi befrikhwensi emaphakathi, isihlungi se-band-stop sivumela amasignali awo wonke amanye amafrikhwensi ukuthi adlule. Lokhu kuvumela izihlungi ze-band-stop ukuthi zisetshenziselwe ukususa umsindo, ukuphazamiseka kanye nokuhlangabezana nezidingo ezithile zokuphendula imvamisa.
3.Ukuhlanekezela kwegagasi elincane: uma kuqhathaniswa nezinye izinhlobo zezihlungi, izihlungi ze-band-stop zinokuhlanekezela kwamagagasi amancane. Lokhu kusho ukuthi ingagcina kangcono umumo nobukhulu besiginali edlula esihlungini.
I-4.Ukucubungula isignali ye-Broadband: Isihlungi se-band-stop singasetshenziselwa ukucubungula amasignali e-broadband, ngoba singagcina izingxenye eziningi zefrikhwensi futhi sivimbele kuphela ububanzi obukhethekile befrikhwensi.
5. Impendulo yesigaba: Ukusabela kwesigaba sesihlungi sokumisa ibhande kuncike ekwakhiweni nasekusetshenzisweni kwaso, kodwa ngokuvamile kuphakathi kwesihlungi sephasi eliphansi nesihlungi se-high-pass.
Ukusetshenziswa kwezihlungi ze-microstrip zenqaba:
1. Ukucutshungulwa kwesignali kagesi: Izihlungi ze-RF band reject zingasetshenziswa ukuhlunga amafrikhwensi athile okuphazamisa ekucubunguleni isignali kagesi, ngaleyo ndlela kuthuthukiswe ikhwalithi yesiginali.
2. Ukuxhumana ngomsakazo: Ekuxhumaneni nomsakazo, izihlungi ezilandula ibhande lomsakazo zingasetshenziselwa ukuhlunga amaza angadingekile kumasignali, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuxhumana.
3. Ama-electronics ahamba phambili: Izihlungi zokumisa ibhande zingasetshenziswa ukulungisa impendulo yemvamisa kumasekhethi ukuze kuzuzwe ukusebenza kwesekethe edingekayo.
4. Imishini yezokwelapha: Izihlungi zokulahla i-coaxial band zingasetshenziswa emishinini yezokwelapha, njengamathuluzi e-electrocardiogram, ukuze kuhlungwe amaza emisipha neminye imithombo yokuphazamiseka yangaphandle.
Qualwaveihlinzeka ngezihlungi zokwenqaba ibhendi ephezulu yokunqatshelwa kububanzi befrikhwensi ye-DC-40GHz. Izihlungi zokulahla ibhande le-microwave zisetshenziswa kakhulu ezinhlelweni eziningi.
