Izixhumi ze-Radio frequency (RF) coaxial, ezaziwa nangokuthi izixhumi ze-RF, ziyizingxenye ezibalulekile ekudluliseni isignali ye-RF/microwave. Baxhuma imigqa yokudlulisa i-coaxial ukuze kusebenze ukuxhumana phakathi kwamadivayisi/amamojula, ukudlulisa ngempumelelo amasiginali e-RF nama-microwave. Zisetshenziswa kakhulu kwezokuxhumana okungenantambo, ukusakaza, ithelevishini, i-radar, neminye imikhakha.
Uma kuqhathaniswa nezinye izingxenye ze-elekthronikhi, izixhumi ze-RF zinomlando omfushane uma kuqhathaniswa. Isixhumi sakuqala se-RF{1}}isixhumi se-UHF-sasungulwa ngo-1930. Phakathi neMpi Yezwe II, ngenxa yezidingo eziphuthumayo zempi kanye nokuthuthukiswa kwe-radar, umsakazo, nokuxhumana nge-microwave, uchungechunge{4}}losayizi ophakathi olufana no-N, C, BNC, ne-TNC lwavela.
Ngemuva kuka-1958, kwavela imikhiqizo emincane efana ne-SMA, SMB, ne-SMC. Ngo-1964, izinga lezempi lase-US i-MIL-C-39012, "Ukucaciswa Okujwayelekile Kwezixhumi Ze-Radio Frequency Coaxial," kwamukelwa. Kusukela lapho kuqhubeke, izixhumi ze-RF zaqala ukuthuthukela ekumisweni, ukukhiqizwa kwe-serialization, kanye nokwenza yonke indawo.
Yiziphi izingxenye ezakha isixhumi se-RF coaxial? Yiziphi izinhlobo ezikhona? Ungasikhetha kanjani isixhumi esilungile se-RF coaxial sohlelo lwakho lokusebenza? Ake sibhekisise.
1. Ukubunjwa kanye Nezimpawu Ze-RF Coaxial Connectors
Izixhumi ze-RF coaxial ngokuvamile zihlanganisa i-conductor yangaphakathi, i-coaxial yangaphandle, i-insulator, nesixhumi. Ama-conductor angaphakathi nangaphandle ayi-conductor emaphakathi kanye nesihlangu sensimbi sangaphandle, ngokulandelana, ahlukaniswe isivikeli sokuvikela ukuvimbela ukuphazamiseka kwesignali nokuvuza. Isixhumi siyingxenye eyinhloko yesixhumi, esetshenziselwa ukufaka noma ukususa ikhanda lesixhumi ukuze kuqedelwe ukudluliswa kwesignali.
Lo mklamo wesakhiwo unikeza izixhumi ze-RF coaxial ukusebenza kahle okuphezulu-okusebenza kokudluliselwa kwemvamisa, amandla aqinile okumelana{1}}nokuphazamisa, kanye nokufaka okulula nokuthembekile.
2. Izindlela zokufaka ze-RF Coaxial Connectors
Izixhumi ze-RF coaxial zingafakwa ngezindlela ezintathu: ukukhwezwa kwamaphaneli (ngokuvamile ngama-flange angu-2-imbobo/4-ama-hole flange), ukukhwezwa kwe-PCB, nokukhwezwa kwekhebula (izixhumi zekhebula). Ukukhwezwa kwamaphaneli kungahlukaniswa futhi kube yinsimbi{5}}ngodonga, i-dielectric ngokusebenzisa-udonga, i-air through-wall, izinhlobo ezikhiphekayo, kanye ne-direct-connect.

3. Ukuhlelwa Kohlobo Lwesixhumi
Izixhumi ze-RF coaxial ziza ngezinhlobo eziningi ezihlukahlukene, ezinochungechunge oluhlonishwa umhlaba wonke olungaphezu kwama-20 kanye nokunye okucaciswe okwengeziwe. Izinhlobo ezijwayelekile zifaka izixhumi ze-BNC, izixhumi ze-SMA, izixhumi ze-N, nezixhumi ze-TNC. Izinhlobo ezahlukene zezixhumi ze-RF coaxial zisetshenziswa ezimeni ezahlukene.
Isibonelo, izixhumi ze-RF coaxial ze-Shenzhen Xinqiyuan Technology zinikela ngezinhlobo zezixhumi ezingafika kwezingama-22, okuhlanganisa u-1.85mm, 2.4mm, 2.92mm, 3.5mm, SMA, SSMA, SMP, SSMP (SMPM), BMA, BNC, TNC, MCX/MMCX0, 4.3/1MB isixhumi esibonakalayo esijwayelekile, N. Isixhumi ngasinye sihambisana ngokuqinile nezindinganiso, sihlangabezana ngokugcwele nezidingo zezicelo ezihlukahlukene zezempi nezohwebo.
