Naqshadeeye filter RF,
Xidhiidhiyayaasha VHF Bandpass Filter N oo ka shaqeeya 140-175MHz, Khasaaraha Gelida Hoose ee Mugga Yar
Filterka VHF Bandpass JX-LPF1-140M175M-40NMF waa hal nooc oo ka mid ah qaybaha RF dadban ee loogu talagalay & ay soo saartay iibka Jingxin, kaas oo si gaar ah u leh astaamo galinta hoose oo ka yar 0.2dB mug yar, oo lagu qiyaasay kaliya 59mm x 39.5mm x 28mm.
Inta jeer ee shaandhada ka gudubka Band waxay dabooshaa 140-175Mhz oo leh xadhkaha baaska ee 35MHz, kaas oo ka hoos shaqeeya awooda 150W. Shaandheeyaha bandpass ee VHF waxaa lagu soo saaray isku xirayaasha N lab iyo N dheddig, laakiin kuwa kale loogu wareejin karo iyadoo loo eegayo baahida. Iyada oo rinjiyeynta midab cawl ah, nooca shaandhada bandpass-ka noocan oo kale ah waxay ku adkeysan kartaa garoonka muddo dheer.
