Ii-PIM eziphantsi ze-Single Directional Couplers RF BroadBand Amandla aphezulu e-Coaial Microwave Millimeter Wave Radio Frequency
I-Low PIM Single Directional Coupler yinxalenye ekhethekileyo ye-RF engasebenziyo eyenzelwe ukusampula amandla esignali phambili okanye ekubuyiseleni umva ngelixa igcina ubumsulwa besignali obugqwesileyo ngokunciphisa i-passive intermodulation distortion (PIM). Ezi couplers zineempawu ezichanekileyo zokudibanisa kwicala elichanekileyo ezibalulekileyo kwiinkqubo zanamhlanje ezingenazingcingo ezisebenza kakhulu.
Iimbonakalo:
1. Ukunyaniseka kweSignali okungaqhelekanga
Uyilo oluphambili lunciphisa ukuphazamiseka kwe-passive intermodulation (PIM). Ulawulo oluphezulu luqinisekisa ukudibana kwesignali ngokuchanekileyo kunye nokuphazamiseka okuncinci. Ukusebenza okuphezulu komgca kugcina ubumsulwa besignali kulo lonke uluhlu lokusebenza.
2. Ukusebenza kweBroadband
Ukugubungela amaza amaninzi kuxhasa iibhendi zonxibelelwano ezininzi. Ukusebenza okuzinzileyo kuzo zonke iinguqu zobushushu kunye neemeko zendalo. Iimpawu zokudibanisa ezihambelanayo kuyo yonke i-bandwidth yokusebenza.
3. Ulwakhiwo Oluqinileyo
Indlu eyakhiwe ngokuchanekileyo inika iipropati zokukhusela ezibalaseleyo. Izinto ezihlala ixesha elide ziyamelana neemeko zokufakelwa ezifuna umgudu omkhulu. I-compact form factor ivumela ukuhlanganiswa kwenkqubo okuguquguqukayo.
4. Ukusebenza okuthembekileyo
Ubuchule obugqwesileyo bokuphatha amandla ukuze isebenze rhoqo. Ukulahleka okuncinci kokufakwa kugcina inkqubo isebenza kakuhle. Ukusebenza okuzinzileyo kwe-VSWR kuqinisekisa umgangatho wesignali ohambelanayo.
Izicelo:
1. Iinkqubo zoNxibelelwano olungenazingcingo
Iinethiwekhi zokuphakelwa kwee-antenna kwisikhululo sesiseko seziseko ze-5G/LTE. Iinkqubo ze-amplifier ezifakwe kwiTower-mounted (TMA). Iinkqubo ze-antenna ezisasazwayo (DAS) zokugubungela ngaphakathi.
2. Uvavanyo kunye nokulinganisa
Ukubeka iliso kwiimpawu kwiinkqubo zovavanyo lwe-RF. Ukudibanisa iireferensi zovavanyo lwe-intermodulation. Ukuqinisekiswa kokusebenza kwenkqubo kunye nokusombulula iingxaki.
3. Inqwelo-moya kunye noKhuselo
Iinkqubo zonxibelelwano lwesathelayithi. Izicelo zeradar kunye nemfazwe ye-elektroniki. Amakhonkco onxibelelwano abalulekileyo kwimisebenzi.
4. Usasazo kunye nonomathotholo woBugcisa
Iinkqubo zokudibanisa i-transmitter. Ukubeka esweni imigca yokusasaza. Iinethiwekhi zokusasaza i-RF ezinamandla aphezulu.
5. Iingenelo zobuGcisa
Yenzelwe ukusebenza okuphantsi kwe-PIM kwizicelo ezifuna amandla amaninzi. Kukho iindlela zokwenza ngokwezifiso eziguquguqukayo. Yenziwe ngezinto ezichanekileyo zokusebenza okuthembekileyo. Uvavanyo lomgangatho olupheleleyo luqinisekisa ukusebenza okuzinzileyo.
I-Qualwaveibonelela ngee-couplers ze-broadband ezisezantsi ze-PIM ezikwi-single directional kuluhlu olubanzi ukusuka kwi-0.555GHz ukuya kwi-2.7GHz. Ezi couplers zisetyenziswa kakhulu kwizicelo ezininzi.
