Ɲiningali fɔlɔ: RF SAW ka bandi filtɛri be baara kɛ cogo min na, an be se k’o sɛgɛsɛgɛ cogo di?
A: 1) Ka donni bɔnɛ suma (i n’a fɔ, -1,5dB ka taga se -3dB ɲɔgɔn ma yɔrɔ cɛmancɛ la) n’i be baara kɛ ni Vecteur Réseau Analyseur (VNA) ye.
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >25dB ni ±100MHz yɛlɛmani ye).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) passband kɔnɔ walisa ka miiri dɔɔni dɔɔni.
Ɲiningali 2: Gɛlɛya minw ka teli ka kɛ ani furakɛcogo minw be sɔrɔ RF SAW filtɛri donɲɔgɔnna na?
A: Ɲɛyirali 1nan: Ɲɛyirali fɛ, mɔgɔw tun be ɲɔgɔn minɛ cogo min na, o tun be se ka kɛ wala Passband Ripple
Kuun: Impedansi tɛ bɛn filtɛri ni PCB lamini tagamasiɲɛ/fɛn impedansi cɛ (a ka ca a la 50Ω).
Labɛn: Sɛgɛsɛgɛ ani ka yɛlɛma donyɔrɔ/bɔyɔrɔ ɲɔgɔndan réseau (misali la, seri walima shunt inductors/capacitors) i n’a fɔ a fɔra cogo min na kunnafonisɛbɛn kɔnɔ.
Ɲiningali 2nan: Bandi banbagatɔ walima tagamasiɲɛ bɔli
A sababu: EMI ɲɔgɔndan min be bɔ yɔrɔ gɛrɛfɛ minw be se ka mɔgɔw lafili wala dugukolo min tɛ se ka don filtɛri ka nɛgɛkunbɛnnan na.
Labɛn: A’ y’a lajɛ ni filɛri dugukolo nɛgɛw nɔrɔnin lo ka ɲɛ ni RF dugukolo nɛgɛ barikaman dɔ ye. Aw ka baara kɛ ni fɛnw ye minw be mɔgɔ tanga ani ka filtɛri bɔ yɔrɔ minw na mankan be kɛ (i n’a fɔ, fanga yɛlɛmalanw, lɛrɛw).
