I-VHF Bandpass Lumped Component Filter Esebenza kusukela ku-155-245MHz
I-VHF band pass LC isihlungi i-JX-LCF1-155M245M-S20 yakhelwe futhi yakhiqizwa ngu-Jingxin. Imvamisa yayo ihlanganisa ukusuka ku-155-245MHz ngebhendi yokudlula engu-90MHz, efaka ukulahlekelwa kokufaka okungaphansi kuka-1.5dB, ukulahlekelwa kokubuyisela ngaphezu kuka-14dB, i-ripple ngaphansi kuka-0.4dB, ukwenqatshwa ngaphezu kuka-20dBc@DC-40MHz & 320-480MHz,60dBc0040Mz . Ikalwe ngo-40.4mm x 12mm x 10mm ngevolumu encane, itholakala ngezixhumi ze-SMA, ezipendwe ngombala omnyama impilo ende.
Njengomklami wesihlungi se-LC, uhlobo olunjalo lwesihlungi esinezigaxa sohlelo lwe-VHF luningi kukhathalogi ye-Jingxin, i-Jingxin ingakusiza kunoma iyiphi inkinga yezingxenye ze-RF ezingenzi lutho. Yenza njengesithembiso, zonke izingxenye ze-RF ezingenzi lutho ezivela ku-Jingxin zinewaranti yeminyaka emi-3.

Izingxenye ze-RF Passive zangokwezifiso
Izinyathelo Ezi-3 Kuphela Zokuxazulula Inkinga Yakho Yengxenye Ye-RF Passive
1.Ukuchaza ipharamitha nguwe.
2.Ukunikeza isiphakamiso sokuqinisekiswa nguJingxin.
3.Ukukhiqiza i-prototype ukuze ihlolwe ngu-Jingxin.
