VHF Bandpass Lumped Component Filter e mahi ana mai i te 155-245MHz
VHF band pass LC tātari JX-LCF1-155M245M-S20 i hangaia & hangaia e Jingxin. Ko tona auau e hipoki ana i te 155-245MHz me te roopu whakawhiti o 90MHz, me te whakaurunga ngaro iti iho i te 1.5dB, te hokinga mai i runga i te 14dB, te ripple i raro i te 0.4dB, te aukati i runga i te 20dBc@DC-40MHz & 320-480MHz,60dBc@00M-10dBc@00M-10dB . I inehia te 40.4mm x 12mm x 10mm i roto i te rōrahi iti, kei te waatea me nga hononga SMA, pania ki te tae pango mo te wa roa.
I te mea ko te Kaihoahoa tātari LC, he nui ake te ahua o te tātari wae mo te punaha VHF kei roto i te raarangi Jingxin, ka taea e Jingxin te awhina i a koe i nga raru o nga waahanga haahi RF. Mahia kia rite ki te oati, ko nga waahanga RF passive katoa mai i Jingxin he 3 tau te whakamana.
