Aplikasiyɔnw
- Ni baarakɛcogow be daminɛ telefɔniw na ka taga a bila sateliti rada la, High Frequency SAW Filter SF55M8 seri (5,0×5,0 mm CERAMIC SEAM SEAL SMD pake kɔnɔ) ye fɛn jɔnjɔn ye min be se ka tagamasiɲɛw minɛ kumaɲɔgɔnya minan sifa caaman na.
Fɛɛn nafaw
-baarakɛcogo ɲuman
Tariku la, a tun be fanga sɔrɔ sub-3GHz low-frequency band kan k’a sababu kɛ nafa dɔw ye i n’a fɔ a dilancogo nɔgɔman, baarakɛcogo basiginin, ani a bonya fitinin, SAW minɛn ye yɛlɛmanibaw ye baarakɛcogo la kɔsa nin na.
Anti-elekitoromanɛtiki ɲɔgɔndan
A ka sebagaya fɛ ka kuran yɛlɛmaniw bɔ ɲɔgɔn na ka ɲɛ, piezoelektriki yɔrɔ (misali la, kuarzi, litiyɔmu niobati) ka ɲi ka kumaɲɔgɔnya baarakɛcogo ɲumanw ɲini i n’a fɔ 5G basigiyɔrɔw ani -mobiliw ka sisitɛmu minw siginin lo ka kɔn.
dipilomu
O 5050 SF55M8 ka sɛgɛsɛgɛrikɛlan be RoHS/REACH ka sariyaw labato ani a tɛ ni pɔtɔmu ye / Halogɛni tɛ yen.
ɲiningaliw
Ɲiningali fɔlɔ: Danfara jɔnjɔn jumanw lo be filɛri minw be kɛ ni surface acoustique wave (SAW) ye, filɛri minw be kɛ ni LC gansanw ye ani filɛli minw be kɛ ni ceramiki ye, ani mun na SAW filɛri be ta ka caya RF minɛnw na?
A: Ni u ka bɔli -ka -bandi sɔgɔli ye, u ka cogoya nɔgɔman, ani u ka frekansi caman datugu RF bandi kɔnɔ (kɛrɛnkɛrɛnniya la, 1GHz sanfɛ), SAW filtɛriw kɛra sugandiliba ye RF ɲɛfɛ-laban kama k’a sɔrɔ u be bɛn koɲuman ni anti{4}}bandiw ka mobilizasiyɔn ani miniG ka yɛlɛmaniw ye.
Ɲiningali 2nan: Fɛɛn jumɛnw lo be se ka kɛ ka fɛnw mara wagatijan kɔnɔ (SAW) walisa ka baarakɛcogo tiɲɛ?
A: Filtɛri minw be yɛlɛma yɔrɔ la, u fanba be ni pake misɛnninw ye (i n’a fɔ, 0402, 0603 suguw) ani u be se ka sɔgɔsɔgɔ kosɔbɛ ani u be se ka yɛlɛma yɛlɛma ni kuran ye. U maratuma na, u ka kan ka to u ka minan fɔlɔw kɔnɔ wala u ka kan ka to u ka minanw kɔnɔ minw be latanga:
1) Kuran latanga
2)Farikolo latanga: i kana fɛnw ɲɔgɔn lajɛn ka dama tɛmɛ; ka sɔgɔsɔgɔ ani ka gosi bali
3) Jii-fɛn min tɛ jigi
