Product Description
Typical Performance1
BeRex’s Divider BD25B 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 RoHScompliant with SOIC-8 surface mount package. It can be used without back side ground
soldering. (This may degrade the performance at the high frequency edge.)
