Low Pass Filters RF Coaxial High Frekwinsje MicroStrip MilroSpave Millimeter Wave Radio Frequency Suspended Stripline WaveGuide
RF Low Pass Filter is in filterferwurkingsfilter dat lege frekwinsjeignalen bewarret troch it ferwiderjen fan hege frekwinsje. It lit sinjalen mei frekwinsje minder dan in bepaalde drompel om te passearjen, mar signalen fersmyt mei frekwinsjes grutter dan dy drompel.
Funksjes fan Radio Frequency Low Pass Filters:
1. Allinich signalen ûnder in spesifike frekwinsje meie trochgean, wylst signalen boppe dy frekwinsje wurde filtere of ferswakke.
2. As jo trochgean troch signalen fan leechfrekwinsje, is d'r hast gjin feroaring yn faze.
3. Normaal wurde ien of mear kondensatoren en incuctors brûkt om telecom-filters te konstruearjen.
Oanfraach fan Coaxiale lege pasfilters:
1.S.mOOCK sinjaal
Hege frekwinsje leechpasfilter wurdt fral brûkt om it sinjaal te glêdjen, it kin it lûd ferwiderje yn it signaal mei hege frekwinsje, sadat it sinjaal stabyl wurdt. Yn gefallen wêr't in glêde sinjaal nedich is, kin it MicroStrip Filter fan Low-Pass-leech-frekwinsje ynterferinsje ferwiderje, dus it systeem betrouber en stabyl meitsje.
2.Nederland reduksje
Low Pass filter sil ynfloed hawwe op it sinjaal fan it leechfrekwinsje, wylst jo it lege frekwinsje-sinjaal behâld hawwe, kin lûd wurde filtere. Yn audioferwurking as ôfbyldingsferwurking, kinne jo lege pas filters filterje út en meitsje de ferwurke sinjaal dúdliker.
3.DuCuce de flater
LOW PASFILS kin de flater ferminderje, foaral geskikt foar mjitting foar presys. Yn guon easkende mjittingen kinne it lege pas-filter lûd, ynterferinsje ferwiderje, ynterferinsje en oare faktoaren, sadat de mjitresultaten krekter en betrouber binne.
4.Wideo oanbod fan tapassing
Millimeter Wave Low Pass Filter hat in heul breed oanbod fan applikaasjes, fan Audio nei ôfbylding, fan kommunikaasje om te kontrolearjen, hast oeral. Bygelyks yn baseband-sinjaalferwurking, lyts grutte lege pasfilter is nedich.
Yn kommunikaasje kin ophâlden lege pass filter kinne filterje út it lûd fan hege frekwinsje, ynterferinsje, ensfh., Om kommunikaasjewaliteit te garandearjen; Op it mêd fan kontrôle kin it stripline leechpasfilter kinne wurde brûkt foar sinjaal glêd en lûdfiltering.
Kwalwaveleveringen Mikrowave Low Pass filters yn frekwinsje berik DC-50ghz. De Waveguide Lege Pass Filters wurde breed brûkt yn in protte applikaasjes.
