Application
RF filter for WLL (Wireless Local Loop)
Features
SMD filter consisting of coupled resonators with stepped impedances
MgTiO3-CaTiO3 (
r = 21 / TCf =010 ppm/K) with a coating of copper (10
m) and tin (>5
m)
Excellent reflow solderability, no migration effect due to copper/tin metallization
ESD insensitivity and ESD protecting due to filter characteristics
