 Lead-free/RoHS-compliant SOIC-8 Plastic Package
With exposed back side ground pad
Product Description
BeRex’s Divider BD09B is designed for Cellu-
lar & GSM band with low Insertion Loss and
Isolation. This chip is fully passivated for en-
hanced performance and reliability and
packaged in RoHS-compliant with SOIC-8
surface mount package.
It can be used without back side ground sol-
dering. (This may degrade the performance
at the high frequency edge.)
