Type: EFSD२२२२F२२२
EFSD२२२२J२२२
SAW Devices(SAW Duplexers)
SAW Duplexer for Cellular Telephone which incorporates
highly-precise interdigited electrodes achieves low
insertion loss, high selectivity. And unique electrode
material achieves high power durability thus the
duplexer has wide applications to antenna duplexer
circuits for cellular telephones.
Features
Stable against severe conditions of vibration and
shock thanks to the unique monolithic construction of
the filter
Low insertion loss and excellent selectivity
Contributes to circuit simplification and adjustment free
Saves the hight on PC board
Recommended Applications
The antenna duplexer for cellular telephone
