Yintoni iRF / iMicrowave Filter?

Iifrikhwensi zikanomathotholo (RF) kunye nezihluzo ze-microwave zichazwa njengodidi lwesihluzo sombane, eziyilelwe ukusebenza kwiimiqondiso kwi-megahertz ukuya kwigigahertz amaza amaza (amaza aphakathi aphakathi ukuya phezulu kakhulu). Olu luhlu lwefrikhwensi yesihluzo luluhlu olusetyenziswa luninzi losasazo lukanomathotholo, umabonakude, unxibelelwano olungenazingcingo (iiselfowuni, iWi-Fi, njl.njl.), kwaye ke ngoko uninzi lwezixhobo zeRF kunye ne-microwave ziya kubandakanya uhlobo oluthile lokucoca kwiimpawu ezigqithisiweyo okanye ezifunyenweyo. Ezo zihluzo ziqhele ukusetyenziswa njengeebhloko zokwakha zeeduplexer kunye nediplexers ukudibanisa okanye ukwahlula iibhendi zamaza amaninzi.

Imisebenzi:
1. Isihluzi se-Rf sinokunciphisa ukuphazamiseka kwebhendi kunye nokuphucula ukusebenza kwezixhobo ezikuyo.
2. Isihluzo se-RF sivumela kuphela amaza kunye nejelo elisasazwayo okanye elifunyenweyo ukuba lidlule kwaye linciphisa ukuphazamiseka komqondiso ngaphandle kwejelo.

Ngokwesiseko somsebenzi wayo, ngokoluhlu lwamaxesha omqondiso wokusebenza ukwahlula izihluzi zeRF, zahlulwe ikakhulu zibe ziindidi ezine, oko kukuthi, isihluzo sokupasa esisezantsi (LPF), isihluzi sokupasa okuphezulu (HPF), isihluzo sokupasa ibhendi ( BPF) kunye ne-band stop filter (BSF).

1. Isihluzi esikwinqanaba elisezantsi: Sibhekisa kwisihluzi apho isiginali yefrikhwensi ephantsi inokudlula kodwa isignali ephezulu ayinakudlula;
2. Isihluzi se-High-pass filter: Yinto echaseneyo, oko kukuthi, imiqondiso ye-frequency ephezulu inokudlula kwaye imiqondiso ephantsi-frequency ayikwazi ukudlula;
3. Isihluzo se-Band-pass: Sibhekisa kumaza ohlobo oluthile lweempawu ezinokudlula, isihluzo se-RF nangaphandle koluhlu lwamaza emiqondiso ayinakudlula;
4. Isihluzo sokumisa ibhendi: Ukusebenza kwesihluzo sokumisa ibhanti kuchasene, oko kukuthi, imiqondiso kuluhlu lwebhendi ivaliwe, kodwa imiqondiso engaphandle kolu luhlu lwamaza ivumelekile ukuba idlule;

Izihluzi ze-RF zinokuhlelwa ngokwe-SAW filter, i-BAW filter, i-LC filter, i-cavity filter, isihluzo se-ceramic ngokwesakhiwo okanye imathiriyeli yazo ngokunjalo.

Jingxin, njengengcaliumenzi wamalungu e-RF asebenzayo, inokubonelela ngezi zihluzo zeRF zingentla ukuze zibhekiselele, eziye zaphuhlisa ngaphezu kweminyaka eyi-10 ukuyila nokuvelisa izihluzi zeRF ukwenzela izicelo ezahlukeneyo, njengesisombululo se-DAS, inkqubo ye-BAD, unxibelelwano lwasemkhosini, kunye nokuzuza indumiso ephezulu ngokufezekiswa kwayo. abathengi. Izihluzi zoyilo lwesiko zinokwenziwa nguJingxin ngokwengcaciso kwakhona, umbuzo omninzi wamkelekile.
