Izihlungi ze-Bandstop/Isihlungi se-Notch sidlala indima ebalulekile emkhakheni wezokuxhumana ngokukhetha ngokukhetha ukuncisha ububanzi obukhethekile befrikhwensi futhi sicindezele amasiginali angafuneki.Lezi zihlungi zisetshenziswa kakhulu ezinhlelweni ezahlukahlukene zokuthuthukisa ukusebenza nokuthembeka kwezinhlelo zokuxhumana.
Izihlungi ze-Bandstop zithola ukusetshenziswa okubanzi ezindaweni ezilandelayo:
Ukucindezelwa Kwesiginali kanye Nokuqedwa Kokuphazamiseka: Izinhlelo zokuxhumana zivame ukuhlangana nezinhlobo ezahlukene zezimpawu zokuphazamiseka, njengalezo ezivela kwamanye amadivaysi angenawaya kanye nokuphazamiseka kokunikezwa kwamandla.Lokhu kugxambukela kungehlisa isithunzi ukwamukela kwesistimu namandla okulwa nokugxambukela.Izihlungi ze-Bandstop zicindezela ngokukhetha amasignali okuphazamisa, okuvumela isistimu ukuthi yamukele futhi icubungule amasignali afiswayo ngempumelelo kakhudlwana[[1]].
Ukukhethwa kwebhendi yefrikhwensi: Kwezinye izinhlelo zokusebenza zokuxhumana, kuyadingeka ukukhetha amabhendi athile akhethekile wokudlulisa isignali nokwamukela.Izihlungi ze-Bandstop zenza kube lula ukukhetha ibhendi ngokukhetha ukudlulisa noma ukunciphisa amasiginali phakathi kwamabanga athile.Isibonelo, ekuxhumaneni okungenantambo, amabhendi esignali ahlukene angase adinge ukucutshungulwa nokudluliswa okuhlukile.Izihlungi ze-Bandstop zisiza ekukhetheni nasekulungiseni amasignali ngaphakathi kwamabhendi athile efrikhwensi ukuze ahlangabezane nezidingo zezinhlelo zokuxhumana
Ukulungiswa Kwesiginali Nokuthuthukisa: Izihlungi ze-Bandstop zingasetshenziswa ukulungisa impendulo yemvamisa futhi zithole izici zamasiginali ezinhlelweni zokuxhumana.Amasistimu athile okuxhumana angase adinge ukuncishiswa noma ukuthuthukiswa kwamasignali phakathi kwebanga elithile lefrikhwensi.Izihlungi ze-Bandstop, ngedizayini efanele kanye nokulungiswa kwepharamitha, zivumela ukulungiswa kwesignali nokwenza ngcono ukuthuthukisa ikhwalithi yokuxhumana nokusebenza kwesistimu.
Ukucindezelwa Komsindo Wamandla: Umsindo wokuphakelwa kwamandla uyinkinga evamile ezinhlelweni zokuxhumana.Umsindo wokuphakelwa kwamandla ungasabalala emishinini yokuxhumana ngokusebenzisa izintambo zikagesi noma amanethiwekhi okuphakela, okubangela ukuphazamiseka ekwamukelweni kwesignali nokudluliswa.Izihlungi ze-Bandstop zingase zisetshenziswe ukucindezela ukusakazeka komsindo wokunikezwa kwamandla, ukuqinisekisa ukusebenza okuzinzile nokwamukela isignali okunembile ezinhlelweni zokuxhumana.
Izinhlelo ezibanzi zezihlungi ze-bandtop emkhakheni wezokuxhumana zifaka isandla kakhulu ekuthuthukiseni ukusebenza kwesistimu nokuthembeka.Ngokukhetha ukucindezela amasignali okuphazamisa, ukuvumela ukukhethwa kwebhendi yefrikhwensi, ukulungisa amasignali, kanye nokucindezela umsindo wokuphakelwa kwamandla, izihlungi ze-bandstop zithuthukisa ukudluliswa kwesignali nekhwalithi yokwamukela, zihlangabezana nezidingo ezihlukahlukene zezinhlelo zokuxhumana.
I-Concept Microwave ihlinzeka ngohlu oluphelele lwezihlungi ze-notch ukusuka ku-100MHz ukuya ku-50GHz, ezisetshenziswa kakhulu ekusetshenzisweni kwe-Telecom Infrastructures, Satellite Systems, 5G Test & Instrumentation&EMC kanye neMicrowave Links.
