VHF Bandpass Lumped Component Filter o lo'o galue mai le 155-245MHz
VHF band pass LC faamama JX-LCF1-155M245M-S20 ua mamanuina & gaosia e Jingxin. O lona alapine e aofia ai le 155-245MHz ma le pasi o le 90MHz, faʻaalia i lalo ifo o le 1.5dB le gau, toe leiloa i luga ole 14dB, galu i lalo ole 0.4dB, teena ile 20dBc@DC-40MHz & 320-480MHz,60dBc@00M-60dBc@00M- . Fua 40.4mm x 12mm x 10mm i le voluma laiti, o loʻo avanoa ma fesoʻotaʻiga SMA, valiina i le lanu uliuli mo le ola umi.
I le avea ai o le LC filter designer, o sea ituaiga o mea faʻapipiʻi vaega mo le VHF e sili atu i le Jingxin catalog, e mafai e Jingxin ona fesoasoani ia te oe i soʻo se faʻafitauli o vaega RF passive. Faia e pei o le folafolaga, o vaega uma RF passive mai Jingxin e 3 tausaga faʻamaonia.
