Siyini Isihlungi se-RF/Microwave?

Ifrikhwensi yomsakazo (RF) nezihlungi ze-microwave zichazwa njengohlobo lwesihlungi se-elekthronikhi, esiklanyelwe ukusebenza kumasiginali ku-megahertz kuya kububanzi befrikhwensi ye-gigahertz (ifrikhwensi emaphakathi ukuya kumafrikhwensi aphezulu kakhulu). Lolu hlu lwamafrikhwensi luwububanzi obusetshenziswa umsakazo osakazwa kakhulu, umabonakude, ukuxhumana okungenantambo (omakhalekhukhwini, i-Wi-Fi, njll.), futhi ngenxa yalokho iningi lemishini ye-RF ne-microwave izobandakanya uhlobo oluthile lokuhlunga kumasiginali adluliswayo noma awamukelwe. Izihlungi ezinjalo zivame ukusetshenziswa njengamabhulokhi wokwakha ama-duplexer nama-diplexer ukuze ahlanganise noma ahlukanise amabhande amafrikhwensi amaningi.

Imisebenzi:
1. Isihlungi se-Rf singanciphisa ukuphazamiseka kwebhendi yefrikhwensi futhi sithuthukise ukusebenza kwezisetshenziswa ezibekwe ngokuhlanganyela.
2. Isihlungi se-RF sivumela kuphela ifrikhwensi neshaneli esakazwayo noma eyamukelwe ukuba idlule futhi sinciphisa ukuphazamiseka kwesignali ngaphandle kweshaneli.

Ngokwesisekelo somsebenzi wayo, ngokuya ngebanga lemvamisa yesiginali yokusebenza yokuhlukanisa izihlungi ze-RF, zihlukaniswe ikakhulukazi izigaba ezine, okungukuthi, isihlungi sokudlula okuphansi (LPF), isihlungi sokudlula okuphezulu (HPF), isihlungi sokudlula ibhendi ( BPF) kanye nesihlungi sokumisa ibhande (BSF).

1. Isihlungi se-low-pass : Sibhekisela kusihlungi lapho isignali yefrikhwensi ephansi ingadlula khona kodwa isignali yefrikhwensi ephezulu ayikwazi ukudlula;
2. Isihlungi se-High-pass: Kungokuphambene, okungukuthi, amasignali amafrikhwensi aphezulu angadlula futhi amasignali amaza aphansi awakwazi ukudlula;
3. Isihlungi se-band-pass: Sibhekisela kumafrikhwensi ochungechunge oluthile lwamasignali angadlula, isihlungi se-RF nangaphandle kwebanga lefrikhwensi yamasignali ayikwazi ukudlula;
4. Isihlungi sokumisa ibhendi: Ukusebenza kwesihlungi sokumisa ibhendi kuphambene, okungukuthi, amasiginali ebangeni lebhendi avinjelwe, kodwa amasiginali angaphandle kwalobu bubanzi befrikhwensi avunyelwe ukudlula;

Izihlungi ze-RF zingahlukaniswa zibe isihlungi se-SAW, isihlungi se-BAW, isihlungi se-LC, isihlungi somgodi, isihlungi se-ceramic ngokuya ngesakhiwo noma impahla yazo futhi.

Jingxin, njengochwephesheumenzi wezingxenye ze-RF ze-passive, inganikeza lezi zihlungi ze-RF ezingenhla ukuze zisetshenziswe, osekuyiminyaka engaphezu kwe-10 yakha futhi ikhiqize izihlungi ze-RF zezinhlelo zokusebenza ezihlukahlukene, njengesixazululo se-DAS, uhlelo lwe-BAD, ukuxhumana kwezempi, futhi zuza ukutuswa okukhulu ngokuzuziwe amaklayenti. Izihlungi zokuklama ngokwezifiso zingenziwa nguJingxin ngokuya ngencazelo futhi, imibuzo eminingi yamukelekile.
