Sivana Pass Low RF Coaxial High Frequency Microstrip Microwave Millimeter Wave Radio Frequency mihantona Stripline Waveguide
RF low pass filter dia sivana fanodinana famantarana izay mitahiry famantarana matetika amin'ny alàlan'ny fanesorana ireo famantarana avo lenta. Izy io dia mamela ny famantarana misy faneriterena latsaky ny tokonana iray, saingy mandà ny famantarana misy faneriterena lehibe kokoa noho io tokonam-baravarana io.
Endri-javatra amin'ny sivana fandalovan'ny radio frequency:
1. Ny famantarana eo ambanin'ny frequence manokana ihany no avela handalo, fa ny famantarana eo ambonin'io frequence io kosa dia voasivana na malemy.
2. Rehefa mandalo amin'ny mari-pamantarana ambany matetika, dia saika tsy misy fiovana eo amin'ny dingana.
3. Matetika, iray na maromaro capacitors sy inductors no ampiasaina mba hanorina telecom sivana ambany pass.
Fampiharana ny sivana ambany pass coaxial:
1.Smooth signal
High frequency low pass filter no tena ampiasaina hanesorana ny signal, afaka manala ny tabataba ao amin'ny signal high-frequency, mba hahatonga ny signal ho marin-toerana kokoa. Amin'ny toe-javatra izay ilaina ny famantarana malefaka, ny sivana microstrip low pass dia afaka manala ny tabataba midadasika matetika, ka mahatonga ny rafitra azo antoka sy azo antoka kokoa.
2.Mihena ny tabataba
Ny sivana fandalovana ambany dia tsy hisy fiantraikany amin'ny mari-pandrefesana ambany, raha mitazona ny mari-pandrefesana ambany, ny tabataba avo lenta dia azo voasivana. Amin'ny fanodinana feo na fanodinana sary, ny sivana ambany dia afaka manivana ny tabataba ary manazava kokoa ny famantarana voavoatra.
3. Ahena ny fahadisoana
Low pass sivana dia afaka mampihena ny fahadisoana, indrindra mety amin'ny fandrefesana fitaovana mazava tsara. Amin'ny fandrefesana sasany mitaky, ny sivana ambany dia afaka manala ny tabataba, ny fitsabahana ary ny antony hafa, mba hahatonga ny valin'ny fandrefesana ho marina sy azo antoka kokoa.
4. Wide fampiharana
Milimeter wave low pass filter dia manana fampiharana maro be, manomboka amin'ny feo ka hatramin'ny sary, manomboka amin'ny fifandraisana ka hatramin'ny fanaraha-maso, saika na aiza na aiza. Ohatra, amin'ny fanodinana famantarana baseband, ilaina ny sivana ambany ambany habe kely.
Amin'ny fifandraisana, ny sivana ambany ambany mihantona dia afaka manivana ny tabataba avo lenta, ny fitsabahana, sns., Mba hiantohana ny kalitaon'ny fifandraisana; Eo amin'ny sehatry ny fanaraha-maso, ny stripline low pass filter dia azo ampiasaina amin'ny fanalefahana ny famantarana sy ny fanivanana ny feo.
Qualwavemamatsy sivana mikraoba ambany mandeha amin'ny elanelana matetika DC-50GHz. Ny sivana fandalovan'ny waveguide dia ampiasaina betsaka amin'ny fampiharana maro.
