Ama-Couplers Aphansi Aqondisa I-Single PIM RF BroadBand Ama-Microwave Anamandla Aphezulu E-Coaial Millimeter Wave Radio Frequency
I-Low PIM Single Directional Coupler iyi-RF ekhethekile engasebenzi eyenzelwe ukusampula amandla esignali angaphambili noma angemuva ngenkathi igcina ubumsulwa besignali obukhethekile ngokunciphisa ukuphambuka kwe-intermodulation (PIM). Lawa ma-coupler anezici eziqondile zokuxhumanisa okuqondile ezibalulekile ezinhlelweni zanamuhla ezingenantambo ezisebenza kahle kakhulu.
Izici:
1. Ubuqotho Besignali Obungavamile
Umklamo othuthukisiwe unciphisa ukuphambuka kwe-passive intermodulation (PIM). Ukuqondisa okuphezulu kuqinisekisa ukuhlangana kwesignali okunembile nokuphazamiseka okuncane. Ukusebenza okuphezulu komugqa kugcina ubumsulwa besignali kulo lonke ibanga lokusebenza.
2. Ukusebenza kwe-Broadband
Ukumbozwa kwemvamisa ebanzi kusekela amabhendi amaningi okuxhumana. Ukusebenza okuzinzile kuzo zonke izinguquko zokushisa kanye nezimo zemvelo. Izici zokuxhuma ezihambisanayo kulo lonke i-bandwidth yokusebenza.
3. Ukwakhiwa Okuqinile
Izindlu ezakhiwe ngendlela enembile zinikeza izakhiwo ezinhle kakhulu zokuvikela. Izinto eziqinile zimelana nezimo zokufakwa ezidinga umzamo omkhulu. Isici sefomu esincane senza kube lula ukuhlanganiswa kwesistimu eguquguqukayo.
4. Ukusebenza Okuthembekile
Ikhono elihle kakhulu lokuphatha amandla ukuze kusebenze njalo. Ukulahlekelwa okuncane kokufakwa kugcina ukusebenza kahle kwesistimu. Ukusebenza okuzinzile kwe-VSWR kuqinisekisa ikhwalithi yesignali ehambisanayo.
Izicelo:
1. Izinhlelo Zokuxhumana Ezingenantambo
Amanethiwekhi okuphakela ama-antenna esiteshini esiyisisekelo engqalasizinda ye-5G/LTE. Izinhlelo ze-amplifier ezifakwe embhoshongweni (TMA). Izinhlelo ze-antenna ezisatshalaliswayo (DAS) zokumboza ngaphakathi.
2. Ukuhlolwa Nokulinganiswa
Ukuqapha isignali ezinhlelweni zokuhlola i-RF. Ukuhlanganiswa kwezinkomba zokuhlola i-intermodulation. Ukuqinisekiswa kokusebenza kwesistimu kanye nokuxazulula izinkinga.
3. Izindiza kanye Nokuvikela
Izinhlelo zokuxhumana zesathelayithi. Izinhlelo zokusebenza ze-radar kanye nezempi ze-elekthronikhi. Izixhumanisi zokuxhumana ezibalulekile emsebenzini.
4. Umsakazo Wokusakaza Nochwepheshe
Izinhlelo zokuhlanganisa ama-transmitter. Ukuqapha imigqa yokudlulisa ukusakaza. Amanethiwekhi okusabalalisa ama-RF anamandla aphezulu.
5. Izinzuzo Zobuchwepheshe
Kwenzelwe ukusebenza okuphansi kwe-PIM ezinhlelweni zokusebenza ezidinga amandla amaningi. Izinketho zokwenza ngokwezifiso eziguquguqukayo ziyatholakala. Kwenziwe ngezingxenye ezinembile zokusebenza okuthembekile. Ukuhlolwa kwekhwalithi okuphelele kuqinisekisa ukusebenza okulinganayo.
I-Qualwaveinikeza ama-couplers aqondene ne-broadband aphansi e-PIM ahlukene kakhulu kusukela ku-0.698GHz kuya ku-2.7GHz. Ama-couplers asetshenziswa kabanzi ezinhlelweni eziningi.
