With exposed back side ground pad

BeRex’s Divider BD23B is designed for PCS,

WCDMA & TD-SCDMA and WiBro band with

low Insertion Loss and Isolation. This chip is

fully passivated for enhanced performance

and reliability and packaged in RoHS-

compliant with SOIC-8 surface mount pack-

age. It can be used without back side ground

soldering. (This may degrade the perform-

ance at the high frequency edge.)
