Shaandheeyaha Qaybta Baadhitaanka ee VHF Lumped oo ka shaqaynaysa 155-245MHz
VHF band pass LC filter JX-LCF1-155M245M-S20 waxaa naqshadeeyay & soo saaray Jingxin. Soo noqnoqoshadeedu waxa ay dabooshaa 155-245Mhz oo wadata xariiqda baaska ee 90MHz, oo ay ku jirto gelinta luminta wax ka yar 1.5dB, soo laabasha luminta 14dB, ka hooseeya 0.4dB, diidmo ka badan 20dBc@DC-40MHz & 320-480MHz,60dBc@480-1 . Cabbiraadda 40.4mm x 12mm x 10mm mug yar, waxaa lagu heli karaa xirayaasha SMA, rinji midab madow ah nolosha dheer.
Sida naqshadeeye shaandhaynta LC, nooca shaandhaynta qaybta burbursan ee nidaamka VHF ayaa aad ugu badan buugga Jingxin, Jingxin ayaa kaa caawin karta dhibaato kasta oo ka mid ah qaybaha RF dadban. Samee ballan qaadka, dhammaan qaybaha RF ee aan tooska ahayn ee Jingxin waxay leeyihiin dammaanad 3 sano ah.
