I-RF High Stopband Rejection Usayizi Omncane weTelecom High Pass Izihlungi
Isihlungi se-high-pass yisihlungi sokucubungula isignali esigcina amasignali amafrikhwensi aphezulu ngokususa amasignali aphansi.
Ivumela amasignali anamaza amakhulu kunomkhawulo othile ukuthi adlule, kodwa yenqaba amasiginali anamaza angaphansi kwalowo mkhawulo. Isihlungi se-passive high-pass isihlungi esakhiwe izingxenye ze-passive (R, L kanye no-C), sisebenzisa isimiso sokuthi ukusabela kwama-capacitor nama-inductors kuyashintsha ngokushintsha kwemvamisa. Izinzuzo zesihlungi se-high-pass yilezi: isifunda silula, asidingi ukunikezwa kwamandla ka-DC, ukuthembeka okuphezulu; Ingakwazi ukucindezela ngempumelelo isignali yefrikhwensi ephansi futhi yenze isignali yefrikhwensi ephezulu idlule. Ukungalungi kwesihlungi se-high-pass ukuthi izinga lokunciphisa likhulu ngokuqhathaniswa, elingase lithinte ukunemba kwesignali; Isignali ku-passband inokulahlekelwa kwamandla, umphumela wokulayisha uyabonakala, futhi ukusetshenziswa kwama-inductors kulula ukubangela ukungeniswa kwe-electromagnetic, futhi ivolumu nesisindo sesihlungi kukhulu uma i-inductance L inkulu, engasebenzi isizinda sefrikhwensi ephansi.
Izihlungi ze-high-pass zivame ukusetshenziswa kumsindo, ividiyo, nokucubungula isithombe ukuze kuthuthukiswe ukucaca kwesignali nokunciphisa umsindo. Ngokwesibonelo:
1. Ukucutshungulwa komsindo: Izihlungi zokudlula okuphezulu zingasetshenziswa ekucutshungulweni komsindo ukuze kwehliswe umsindo wemvamisa ephansi noma amanye amasiginali wefrikhwensi engadingekile, ngaleyo ndlela kuthuthukiswe ikhwalithi yomsindo.
2. Ukucutshungulwa kwesithombe: Ekucutshungulweni kwesithombe, izihlungi zokudlula okuphezulu zingasetshenziswa ukuthuthukisa imininingwane yefrikhwensi ephezulu ezithombeni, zicace kakhudlwana.
3. Ukucutshungulwa kwesignali yenzwa: Izihlungi zokudlula okuphezulu zingasetshenziswa ukuhlunga umsindo wemvamisa ephansi kumasignali enzwa, ngaleyo ndlela kuthuthukiswe ukuthembeka kwesignali nokunemba.
4. Ukuxhumana ngomsakazo: Ekuxhumaneni komsakazo, izihlungi zokudlula okuphezulu zingasetshenziswa ukuhlunga umsindo wefrikhwensi ephansi kanye namasignali okuphazamisa, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuxhumana.
Qualwaveihlinzeka ngezihlungi zokudlula okuphezulu kwe-stopband enqatshelwe ebangeni lemvamisa kufika ku-60GHz. Izihlungi zokudlula okuphezulu zisetshenziswa kabanzi ezinhlelweni eziningi.
