Hawlgalka Shaandheynta Bandpass VHF LC Laga bilaabo 87.5-108MHz oo leh Xidhiidhiyayaasha SMA
JX-LCF-98-20 waa hal nooc oo ka mid ah filtarrada LC band ka shaqeeya 87.5-108MHz oo leh band baaska 20.5MHz ee codsiga VHF. Iyada oo muujinta 50mm x 20mm x 15mm oo leh xiriiriyaha SMA, waxay la kulmeysaa luminta gelinta wax ka yar 2dB, soo noqoshada luminta in ka badan 15dB, diidmo sare oo ka badan 60dB, awoodda shaqada ee hoos timaada 2w.
Nooca nooca bandpass LC filter waxaa si gaar ah loogu talagalay iyadoo loo eegayo xalka VHF, waxaa lagu muujiyey waxqabadka xasilloon ee goobta. Faahfaahin dheeraad ah oo tijaabo ah ayaa la bixin karaa tixraac ahaan. Jingxin waxay bixin kartaa naqshad shaandhaynta LC oo dheeraad ah sida ku cad qeexitaanka. Sidii ballan-qaadku ahaa, dhammaan qaybaha RF dadban ee Jingxin waxay leeyihiin dammaanad 3 sano ah.
