VHF Bandpass Lumped Component Filter Ṣiṣẹ lati 155-245MHz
VHF band pass LC àlẹmọ JX-LCF1-155M245M-S20 jẹ apẹrẹ & ṣejade nipasẹ Jingxin. Igbohunsafẹfẹ rẹ ni wiwa lati 155-245MHz pẹlu ẹgbẹ kọja ti 90MHz, ifihan pẹlu pipadanu ifibọ ti o kere ju 1.5dB, ipadanu ipadabọ lori 14dB, ripple ni isalẹ 0.4dB, ijusile lori 20dBc@DC-40MHz & 320-480MHz,60dBc@480-1 . Iwọn 40.4mm x 12mm x 10mm ni iwọn kekere, o wa pẹlu awọn asopọ SMA, ti a ya ni awọ dudu fun igbesi aye gigun.
Gẹgẹbi oluṣeto àlẹmọ LC, iru iru àlẹmọ paati lumped fun eto VHF jẹ diẹ sii ninu iwe akọọlẹ Jingxin, Jingxin le ṣe iranlọwọ fun ọ ni eyikeyi iṣoro ti awọn paati palolo RF. Ṣe bi ileri, gbogbo awọn paati palolo RF lati Jingxin ni atilẹyin ọja ọdun 3.
