Zosefera Zapamwamba za RF Coaxial Comb Interdigital Microstrip Microwave Millimeter Wave Radio Frequency Spiral Suspended Stripline

Imalola ma siginecha okhala ndi ma frequency akulu kuposa malire ena kuti adutse, koma imakana ma siginecha okhala ndi ma frequency ocheperako. Fyuluta yodutsa kwambiri ndi fyuluta yopangidwa ndi zinthu zopanda kanthu (R, L ndi C), pogwiritsa ntchito mfundo yakuti ma capacitor ndi ma inductors amasintha ndi kusintha kwafupipafupi. Ubwino wa fyuluta yapamwamba ndi: dera ndi losavuta, silifuna magetsi a DC, kudalirika kwakukulu; Imatha kupondereza bwino ma frequency otsika ndikupangitsa kuti ma frequency apamwamba adutse. Kuipa kwa fyuluta yapamwamba kwambiri ndikuti chiwerengero cha kuchepa ndi chachikulu, chomwe chingakhudze kulondola kwa chizindikiro; Chizindikiro mu passband ndi kutaya mphamvu, zotsatira katundu n'zoonekeratu, ndipo kugwiritsa ntchito inductors n'zosavuta kuyambitsa electromagnetic induction, ndipo voliyumu ndi kulemera kwa fyuluta ndi lalikulu pamene inductance L ndi lalikulu, amene si ntchito mu otsika ankalamulira.
Zosefera zapamwamba zimagawidwanso kukhala zosefera zachisa chapamwamba, zosefera za interdigital high pass, spiral high pass filters, zosefera zoyimitsidwa za stripline high pass.
