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-

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.)
