I-RF High Stopband Rejection Ubungakanani obuncinci beTelecom Izihluzi eziPhantsi zokuPasa
Isihluzi sokupasa esisezantsi sisihluzo sokwenza umqondiso ogcina iisignali ezisezantsi ngokususa iisignali eziphezulu.Ivumela imiqondiso enefrikhwensi engaphantsi komda othile ukuba idlule, kodwa iyala imiqondiso enefrikhwensi enkulu kunomqobo.
Iimbonakalo:
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 izihlungi ezisezantsi.
Isicelo:
1.umqondiso ogudileyo
icebo lokucoca elisezantsi lisetyenziswa ikakhulu ukugudisa umqondiso, linokususa ingxolo kwisiginali yefrikhwensi ephezulu, ukuze umqondiso uzinze ngakumbi.Kwiimeko apho isignali egudileyo ifunekayo, isihluzo esisezantsi sinokususa ingxolo yokuphazamiseka kwe-high-frequency, ngaloo ndlela yenza inkqubo ithembekile kwaye izinzile.
2.ukunciphisa ingxolo
icebo lokucoca ulwelo olusezantsi aluyi kuchaphazela umqondiso wefrikhwensi ephantsi, ngelixa ugcina isignali yefrikhwensi ephantsi, ingxolo ephezulu-frequency ingahluzwa ngaphandle.Kwinkqubo yeaudio okanye ukusetyenzwa komfanekiso, izihluzi ezidlulayo ezisezantsi zinokuhluza ingxolo kwaye zenze umqondiso ogqityiweyo ucace ngakumbi.
3.nciphisa impazamo
icebo lokucoca ulwelo olusezantsi lunokunciphisa imposiso, ingakumbi ilungele umlinganiselo wesixhobo esichanekileyo.Kweminye imilinganiselo efunekayo, isihluzo esisezantsi sinokususa ingxolo, ukuphazamiseka kunye nezinye izinto, ukwenzela ukuba iziphumo zokulinganisa zichaneke ngakumbi kwaye zithembeke.
4.uluhlu olubanzi lwesicelo
Isihluzi sokupasa esisezantsi sinoluhlu olubanzi kakhulu lwezicelo, ukusuka kwisandi ukuya kumfanekiso, ukusuka kunxibelelwano ukuya kulawulo, phantse yonke indawo.Ngokomzekelo, kwi-baseband signal processing, isihluzo esisezantsi siyimfuneko.
Kunxibelelwano, isihluzi esisezantsi sinokuhluza ingxolo ephezulu-frequency, ukuphazamiseka, njl., ukuqinisekisa umgangatho wonxibelelwano;Kwinkalo yolawulo, isihluzo esisezantsi-esezantsi singasetyenziselwa ukugudisa umqondiso kunye nokucoca ingxolo.
Qualwaveibonelela nge-stopband ephezulu yokwala izihluzi zokupasa ezisezantsi kuluhlu lwamaza e-DC-28GHz.Izihluzi zokupasa ezisezantsi zisetyenziswa ngokubanzi kwizicelo ezininzi.
