Aplikasiyɔnw
- O yɔrɔ la, LOT ani WiFi SAW Filter F11-SFF11 Series be baara kɛ ni IoT ka daaw ye, so kɔnɔ minan hakilimanw, WiFi siraw, izini ka nɛgɛjuruw ani mobili ka telematiki sisitɛmuw.
Fɛɛn nafaw
A ka ɲi ka bɔ-ka -Bandi banna
A be tagamasiɲɛw bɔ ɲɔgɔn na ani k’u filtɛri kɛ, ka tagamasiɲɛw bali ka don gɛrɛfɛ ani tagamasiɲɛ wɛrɛw la minw tɛ nɛgɛjuru ye walisa ka kunnafoniw jɛnsɛn cogo saniyanin na ani cogo lafiyaman na ISM ani WiFi yɔrɔw la minw fanin be mɔgɔw la.
Donni dɔgɔya ni dilan cogo nɔgɔman ye
A be tagamasiɲɛw fanga dɔgɔya dɔɔni dɔɔni k’a sɔrɔ a be ultra-small form factor mara, min b’a to mɔgɔw be se ka sensitivite ɲuman sɔrɔ ani ka fanga sɔrɔ yɔrɔ-IoT ani telefɔniw dilancogo la.

O yɔrɔ la, a be se ka kɛ ko a be RoHS/REACH ka sariyaw labato, a be ni pɔtɔmu ye ani a tɛ ni halojɛni ye.
Ɲiningali
Ɲiningali: LOT ani WiFi SAW filtɛri F11-SFF11 ka baarakɛcogo nafa jɔnjɔnw ye jumanw ye?
A: 1) A be out-of-band banni ɲuman di walisa ka tagamasiɲɛ minw be gɛrɛfɛ, u ka ɲɔgɔn sɔsɔli bɔ yen.
2) A be ni yɛlɛmani dɔgɔman ye kosɔbɛ, min b’a to tagamasiɲɛw ka tilenninya be sabati ani k’a to mɔgɔw be se k’u yɛrɛ minɛ.
3) A ka bonya n’a ka baarakɛcogo basiginin be nɔgɔya don sɛrɛkiliw dilanni na yɔrɔ-IoT ani WiFi baarakɛcogow la.
Ɲiningali: Mun lo ka kan ka jateminɛ LOT ni WiFi SAW Filter F11 dilanni wagati la?
A: Ɲɛyirali 1nan: Donni tununi min ma lawuli
Kuun: Impedansi tɛ bɛn filtɛri ni circuit lamini cɛ.
Labɛn: A’ y’a lajɛ ni donyɔrɔ ni bɔyɔrɔ (misali la, 50Ω) be bɛn ɲɔgɔn ma ka ɲɛ walisa ka baara kɛ ka ɲɛ.
Ɲɛyirali 2nan: Filtɛri ka baarakɛcogo dɔgɔyara
A sababu: PCB labɛncogo jugu be parazitiw ka sebagaya wala induktansi don.
Labɛn: I ka tugu labɛncogo ladilikanw kɔ, RF tagamasiɲɛw ka surunya ani ka baara kɛ ni dugukolo kan awiyɔn ye min be to ka yɛlɛma.
Tagasogow: lot ani wifi ye filɛri f11, Sinuwa lot ani wifi ye filɛri f11 dilanbagaw, feerekɛlaw
