I-RF High Stopband Rejection Usayizi Omncane we-Telecom Band Yenqaba Izihlungi
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.Isimiso sokusebenza sesihlungi sokunqatshelwa kwebhendi ukuhlaziya isignali yokufaka kusizinda samafrikhwensi, futhi ngokukhetha ucindezela i-amplitude yesiginali ngokuya ngebanga lefrikhwensi eshiwo, ukuze kuzuzwe ukuncishiswa komsindo kumafrikhwensi ashiwo.
Okulandelayo izici zayo 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.
Isicelo:
1. Ukucutshungulwa kwesignali kagesi: Izihlungi zokumisa ibhande zingasetshenziswa ukuhlunga amaza okuthikameza athile ekucubunguleni isignali kagesi, ngaleyo ndlela kuthuthukiswe ikhwalithi yesignali.
2. Ukuxhumana ngomsakazo: Ekuxhumaneni nomsakazo, izihlungi zokumisa ibhande zingasetshenziswa 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 zokumisa ibhande zingasetshenziswa emishinini yezokwelapha, njengamathuluzi e-electrocardiogram, ukuhlunga amafrikhwensi emisipha neminye imithombo yokuphazamiseka yangaphandle.
Qualwaveihlinzeka ngezihlungi zokwenqaba ibhendi ephezulu yokunqatshelwa kububanzi befrikhwensi ye-DC-18GHz.Izihlungi zokwenqaba ibhendi zisetshenziswa kakhulu ezinhlelweni eziningi.
