Izihluzo zokuPasa okuPhantsi RF iCoaxial ePhezulu iMicrostrip iMillimeter yamaza amaza amaza erediyo iFrequency enqunyanyisiweyo yeStripline Waveguide
I-RF low pass filter iyisihluzo sokwenza umqondiso ogcina iisignali ezisezantsi ngokususa iisignali eziphezulu. Ivumela imiqondiso enefrikhwensi engaphantsi komda othile ukuba idlule, kodwa iyala imiqondiso enefrikhwensi enkulu kunomqobo.
Iimpawu zerediyo zokucoca iipasi ezisezantsi:
1. Iisignali kuphela ezingaphantsi kwe-frequency ethile evumelekileyo ukuba zidlule, ngelixa iisignali ezingaphezulu kweso sihlandlo zihluzwayo okanye zenziwe buthathaka.
2. Xa udlula kwiimpawu ze-low-frequency, akukho phantse utshintsho kwisigaba.
3. Ngokuqhelekileyo, i-capacitor enye okanye ngaphezulu kunye ne-inductors zisetyenziselwa ukwakha i-telecom low pass filters.
Ukusetyenziswa kwezihluzo ze-coaxial pass low:
1.Umqondiso ogudileyo
Isihluzi sokudlula esisezantsi sisetyenziswa ikakhulu ukugudisa umqondiso, sinokususa ingxolo kwisiginali yefrikhwensi ephezulu, ukuze umqondiso uzinze ngakumbi. Kwiimeko apho umqondiso ogudileyo ufuneka, i-microstrip low pass filter inokususa ingxolo yokuphazamiseka kwe-high-frequency, ngaloo ndlela yenza inkqubo ithembekile kwaye izinzile.
2.Ukunciphisa ingxolo
Isihluzi sokudlula esisezantsi asiyi kuchaphazela isignali yefrikhwensi ephantsi, ngelixa ugcina isignali yefrikhwensi ephantsi, ingxolo ephezulu-frequency ingahluzwa ngaphandle. Kwinkqubo yeaudio okanye ukusetyenzwa komfanekiso, izihluzi zokudlula ezisezantsi zinokuhluza ingxolo kwaye zenze umqondiso ogqityiweyo ucace ngakumbi.
3.Nciphisa impazamo
Isihluzi sokudlula esisezantsi sinokuyinciphisa imposiso, ngakumbi ifanelekile kumlinganiselo wesixhobo esichanekileyo. Kweminye imilinganiselo enyanzelisayo, isihluzi sokudlula esisezantsi sinokususa ingxolo, ukuphazamiseka kunye nezinye izinto, ukuze iziphumo zomlinganiselo zichaneke ngakumbi kwaye zithembeke.
4.Uluhlu olubanzi lwesicelo
Isihluzi se-Millimeter wave low pass pass inoluhlu olubanzi kakhulu lwezicelo, ukusuka kwisandi ukuya kumfanekiso, ukusuka kunxibelelwano ukuya kulawulo, phantse kuyo yonke indawo. Umzekelo, ekusetyenzweni kwesignali ye-baseband, isihluzo esincinci esisezantsi siyimfuneko.
Kunxibelelwano, isihluzo esinqunyanyisiweyo sokupasa esisezantsi sinokuhluza ingxolo ephezulu, ukuphazamiseka, njl., ukuqinisekisa umgangatho wonxibelelwano; Kumhlaba wolawulo, isihluzo se-stripline low pass singasetyenziselwa ukugudisa umqondiso kunye nokucoca ingxolo.
QualwaveIbonelela ngezihluzi zokupasa eziphantsi kwi-microwave kuluhlu lwamaza e-DC-50GHz. Izihluzi ze-waveguide pass low zisetyenziswa ngokubanzi kwizicelo ezininzi.
