VHF Tunable Fyuluta Yogwira Ntchito Kuchokera ku 152-174MHz Yokhala Ndi N Connectors
VHF fyuluta JX-SF1-152174-215N ndi mtundu umodzi wa fyuluta yosinthika ya VHF yomwe ikugwira ntchito kuchokera ku 152-174MHz yokhala ndi bandwidth ya 5-15MHz. kutaya pansi pa 0.5-2.2dB m'mabwalo osiyanasiyana, kubwereranso kutayika kwa 20dB, komanso kukana kwakukulu.
Zosefera zamtundu wotere zimapangidwira kuti zisinthe ma frequency ake molingana ndi ma frequency osinthika, kotero zitha kugwiritsidwa ntchito kwambiri pamayankho a VHF. Monga wopanga zosefera za RF, zosefera zomwe zimatha kusinthidwa zimatha kusinthidwanso. Monga momwe analonjezedwa, zigawo zonse za RF zomwe zili ku Jingxin zili ndi chitsimikizo cha zaka 3.

Custom RF Passive Components
Monga wopanga zigawo za RF zopanda pake, Jingxin akhoza kupanga zosiyanasiyana malinga ndi ntchito za makasitomala.
Njira zitatu Zokha Zothetsera Vuto Lanu la RF Passive Component
1. Kufotokozera gawo ndi inu.
2. Kupereka malingaliro kuti atsimikizidwe ndi Jingxin.
3. Kupanga chitsanzo choyesedwa ndi Jingxin.
