Penjo ma ji penjoga
1: Ere kaka inyalo ng’e ni ng’ato nyalo ng’eyo kaka ng’ato tiyo maber?
1) Pim ng’ado bura (kaka -1.5dB nyaka -3dB e frekwensi ma diere) ka itiyo gi gino ma ng’ato nyalo ng’ado bura (VNA).
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >25dB e ± 100 mHz).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) e kind band mar kalo mondo oket ler matin ahinya.
Q2: Weche ma pile & dwoko mag RF SAW filta?
A: Wach mar 1: Ketho ma ok ogeno mar keto kata ng’injo mar band mar kalo
Gimomiyo: Impedans ok chalre e kind filta kod impedans mar PCB ma ochung’ne (ma thothne en 50Ω).
Fix: Rang’ kendo loso mbui ma luwore gi gik ma donjo/wuok (kaka, gik ma luwore kata ma wuok) kaka ondik e oboke mar weche.
Wach mar 2: Owuok marach mar Band kata Signal ma Owuok
Gimomiyo: Riwruok mar EMI kowuok e gik ma nyalo chocho gik moko machiegni kata piny ma ok oromo e wi filta ma geng’o filta.
Fix: Ne ni filta ma ni e piny osesolde maber e ndege ma nigi RF motegno ma ni e piny. Ti kod kanyo mag geng'o kendo ipog filta kuom sakiut ma nigi koko (kaka, gigo mamedo teko, saa).
