Model BD3238N5050AHF
Rev A
Ultra Low Profile 0404 Balun
50Ω to 50Ω Balanced
Description
The BD3238N5050AHF is a low cost, low profile sub-miniature unbalanced to
balanced transformer designed for differential inputs and output locations on modern
chipsets in an easy to use surface mount package covering 3200MHz to 3800MHz.
The BD3238N5050AHF is ideal for high volume manufacturing and delivers higher
performance than traditional ceramic baluns. The BD3238N5050AHF has an
unbalanced port impedance of 50Ω and a 50Ω balanced port impedance. This
transformation enables single ended signals to be applied to differential ports on
modern integrated chipsets. The output ports have equal amplitude (-3dB) with 180
degree phase differential. The BD3238N5050AHF is available on tape and reel for
pick and place high volume manufacturing.

Mounting Configuration:
In order for Xinger surface mount components to work optimally, the proper impedance transmission lines must be
used to connect to the RF ports. If this condition is not satisfied, insertion loss, Isolation and VSWR may not meet
published specifications.
All of the Xinger components are constructed from organic PTFE based composites which possess excellent
electrical and mechanical stability. Xinger components are compliant to a variety of ROHS and Green standards and
ready for Pb-free soldering processes. Pads are Gold plated with a Nickel barrier.
An example of the PCB footprint used in the testing of these parts is shown below. In specific designs, the
transmission line widths need to be adjusted to the unique dielectric coefficients and thicknesses as well as varying
pick and place equipment tolerances.
