BD25B Quadruple Band 2-Way SMT Power Divider 1700~2500MHz USPCS & PCS, WCDMA & TD-SCDMA, WiBro Device Features Typical Isolation = 23 dB Typical Insertion Loss = 0.5 dB MSL 3 moisture rating Lead-free/RoHS-compliant SOIC-8 Plastic Package With exposed back side ground pad 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.)
