2.92mm ya cholumikizira wamba RF

2.92mm coaxial cholumikizira ndi mtundu watsopano wa cholumikizira cha millimeter wave coaxial chokhala ndi m'mimba mwake wa kondakitala wakunja wa 2.92mm ndi kulephera kwa 50 Ω.Mndandanda wa zolumikizira za RF coaxial zidapangidwa ndi Wiltron.Old mu 1983 Field engineers apanga mtundu watsopano wa cholumikizira kutengera kale anapezerapo millimeter wave cholumikizira, wotchedwanso K-mtundu cholumikizira, kapena SMK, KMC, WMP4 cholumikizira.

Kugwira ntchito pafupipafupi kwa cholumikizira cha 2.92mm coaxial kumatha kufika 46GHz pamwamba kwambiri.Ubwino wa mzere wotumizira mpweya umagwiritsidwa ntchito pofotokozera, kotero kuti VSWR yake ndi yotsika komanso kutayika koyikirako kumakhala kochepa.Mapangidwe ake ndi ofanana ndi 3.5mm / SMA chojambulira, koma gulu lafupipafupi ndilothamanga ndipo voliyumu ndi yaying'ono.Ndi amodzi mwa zolumikizira zomwe zimagwiritsidwa ntchito kwambiri pa millimeter wave padziko lapansi.Ndi malo a millimeter wave coaxial teknoloji mu zida zoyesera asilikali ku China, 2.92mm coaxial connectors akhala akugwiritsidwa ntchito kwambiri mu radar engineering, countermeasures zamagetsi, mauthenga a satana, zida zoyesera ndi zina.

2.92mm main performance indexes

Kusokoneza kwakhalidwe: 50 Ω

Nthawi zambiri: 0 ~ 46GHz

Chiyankhulo maziko: IEC 60169-35

Kukhazikika kwa cholumikizira: 1000 nthawi

Monga tanena kale, zolumikizira za cholumikizira cha 2.92mm ndi cholumikizira cha 3.5mm/SMA ndizofanana, chifukwa kuyanjana ndi SMA ndi mtundu wa 3.5 kumaganiziridwa bwino pamapangidwe amkati ndi akunja ndi mawonekedwe a nkhope yomaliza a cholumikizira.

Monga momwe tawonetsera mu Table 1, miyeso ya zolumikizira zachimuna ndi zazikazi za mitundu itatu ya zolumikizira izi ndizokhazikika, ndipo mwamalingaliro, zimatha kulumikizidwa popanda kusintha.Komabe, ziyenera kukumbukiridwa kuti kukula kwawo kwakunja kwa conductor, ma frequency apamwamba, insulating dielectric materials, etc. ndizosiyana kwambiri, kotero kuti ntchito yopatsirana ndi kulondola kwa mayeso zidzakhudzidwa pamene mitundu yosiyanasiyana ya zolumikizira imagwiritsidwa ntchito polumikizana.Zimanenedwanso kuti cholumikizira chachimuna cha SMA chili ndi zofunikira zochepa zololera pakuzama kwa pini ndi kukulitsa kwa pini.Ngati cholumikizira chachimuna cha SMA chikalowetsedwa mu cholumikizira chachikazi cha 3.5mm kapena 2.92mm, kugwiritsa ntchito nthawi yayitali kungayambitse kuwonongeka kwa cholumikizira chachikazi, makamaka kuwonongeka kwa cholumikizira chachidutswa chowongolera.Chifukwa chake, ngati zolumikizira zosiyanasiyana zalumikizidwa, kulumikizana kotereku kuyeneranso kupewedwa momwe mungathere.
