Applications
RF filter for DECT standard (Digital Enhanced Cordless Telecommunications)
Features
SMD filter consisting of coupled resonators with stepped impedances
(NdBa)TiO3 (εr = 88/TCf = 0 ±10 ppm/K) with a coating of copper (10
μm)
and tin (>5
μm)
Excellent reflow solderability, no migration effect due to copper/tin metallization
