Tlhaloso
VHF Bandpass Lumped Component Filter E sebetsang ho tloha 155-245MHz
VHF band pass LC filthara JX-LCF1-155M245M-S20 e entsoe le ho hlahisoa ke Jingxin . Khafetsa ea eona e akaretsa ho tloha ho 155-245MHz le sehlopha sa pasa sa 90MHz, se nang le tahlehelo ea ho kenya e ka tlase ho 1.5dB, tahlehelo ea ho khutla ho feta 14dB, ripple e ka tlase ho 0.4dB, ho hana ho feta 20dBc@DC-40MHz & 320-480MHz,60dBc000000000M. . E lekantsoe 40.4mm x 12mm x 10mm ka molumo o monyane, e fumaneha ka lihokelo tsa SMA, tse pentiloeng ka 'mala o motšo bakeng sa bophelo bo bolelele.
Joalo ka moetsi oa sefahla sa LC, mofuta o joalo oa filthara ea likarolo tsa VHF o fumaneha lethathamong la Jingxin, Jingxin e ka u thusa bothateng bofe kapa bofe ba likarolo tsa RF tse sa sebetseng. Etsa joalo ka ts'episo, likarolo tsohle tsa RF tse tsoang ho Jingxin li na le waranti ea lilemo tse 3.
