Product Description
BeRex’s Divider BD19B is designed for PCS,
WCDMA & TD-SCDMA band with low Inser-
tion Loss and Isolation. This chip is fully pas-
sivated for enhanced performance and reli-
ability 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.)
*All specifications apply to the following test conditions,
1. Device performance _ measured on BeRex E/B at 25
°C, 50ohm system.
2. Insertion Loss: Above 3.0dB.
3. Back side ground _ soldered.
