RF coaxial switch ndi chipangizo chomwe chimagwiritsidwa ntchito mu RF ndi makina olumikizirana ma microwave kuti akhazikitse kapena kusinthana kulumikizana pakati panjira zosiyanasiyana za chingwe cha coaxial. Zimalola kusankha njira yolowera kapena yotulutsa kuchokera ku zosankha zingapo, kutengera kasinthidwe komwe mukufuna.
Makhalidwe awa:
1. Kusintha mwachangu: Ma RF coaxial switch amatha kusintha mwachangu pakati pa njira zosiyanasiyana za RF, ndipo nthawi yosinthira nthawi zambiri imakhala pamlingo wa millisecond.
2. Kutayika kwapang'onopang'ono: Kusintha kosinthika kumakhala kophatikizana, ndi kutayika kwa chizindikiro chochepa, chomwe chingatsimikizire kufalikira kwa khalidwe la chizindikiro.
3. Kudzipatula kwakukulu: Kusintha kuli ndi kudzipatula kwakukulu, komwe kungachepetse bwino kusokoneza pakati pa zizindikiro.
4. Kudalirika kwakukulu: Kusintha kwa RF coaxial kumagwiritsa ntchito zipangizo zamakono komanso zamakono zamakono zopangira, zomwe zimakhala zodalirika komanso zokhazikika.
Malingaliro a kampani Qualwaves IncRF coaxial switches yokhala ndi ma frequency a DC ~ 110GHz komanso moyo wofikira mpaka 2 miliyoni.
Nkhaniyi ikuwonetsa ma switch a 2.92mm coaxial a DC~40GHz ndi SP7T~SP8T.
