I-RF High Stopband Rejection encinci yeTelecom High Pass Filters
Isihluzi esikwinqanaba eliphezulu sisihluzo sokwenza umqondiso ogcina iisiginiji ezihamba rhoqo ngokususa imiqondiso ephantsi.
Ivumela imiqondiso eneefrikhwensi ezinkulu kunomda othile ukuba idlule, kodwa iyala imiqondiso enezandi ezingaphantsi kwalo mda. I-passive high-pass filter yi-filter eyenziwe ngamacandelo angenayo (i-R, L kunye ne-C), isebenzisa umgaqo wokuba ukusabela kwe-capacitors kunye ne-inductors kuyatshintsha kunye nokutshintsha rhoqo. Iingenelo ze-high-pass filter zezi: isekethe ilula, ayifuni umbane we-DC, ukuthembeka okuphezulu; Inokucinezela ngokufanelekileyo isignali ephantsi yefrikhwensi kwaye yenze isiginali yefrikhwensi ephezulu idlule. Ukungalungi kwesihluzo esiphezulu kukuba izinga lokunciphisa lilikhulu, elinokuthi lichaphazele ukuchaneka komqondiso; Isibonakaliso kwi-passband inokulahlekelwa kwamandla, umphumo womthwalo uyabonakala, kwaye ukusetyenziswa kwee-inductors kulula ukubangela ukufakwa kwe-electromagnetic, kwaye umthamo kunye nobunzima bokucoca bukhulu kakhulu xa i-inductance L inkulu, engasetyenziswanga isizinda samaza aphantsi.
Izihluzi ze-high-pass ziqhele ukusetyenziswa kwi-audio, ividiyo, kunye nokulungiswa kwemifanekiso ukuphucula ukucaca komqondiso kunye nokunciphisa ingxolo. Umzekelo:
1. Ukucutshungulwa komsindo: Izihlungi eziphezulu zokupasa zingasetyenziselwa ukucutshungulwa komsindo ukwenza buthathaka ingxolo ye-low-frequency okanye ezinye iisignali ezingeyomfuneko eziphantsi, ngaloo ndlela ziphucula umgangatho womsindo.
2. Ukucutshungulwa komfanekiso: Ekuqhubekeni komfanekiso, izihlungi zokupasa eziphezulu zingasetyenziselwa ukuphucula iinkcukacha eziphezulu zefrikhwensi kwimifanekiso, zicace ngakumbi.
3. Ukulungiswa komqondiso we-Sensor: Izihlungi eziphezulu zokupasa zingasetyenziselwa ukucoca ingxolo ye-low-frequency kwimiqondiso ye-sensor, ngaloo ndlela iphucula ukuthembeka kwesignali kunye nokuchaneka.
4. Unxibelelwano lukanomathotholo: Kunxibelelwano lukanomathotholo, izihluzi zokupasa okuphezulu zingasetyenziselwa ukuhluza ingxolo ephantsi-izandi kunye nemiqondiso yokuphazamiseka, ngaloo ndlela kuphuculwe umgangatho wonxibelelwano.
QualwaveIbonelela nge-stopband ephezulu yokulahlwa kwezihluzi zokupasa eziphezulu kuluhlu lwamaza ukuya kuthi ga kwi-60GHz. Izihluzi zokupasa eziphezulu zisetyenziswa ngokubanzi kwizicelo ezininzi.
