RevA
Ultra Low Profile Halogen Free
0404 Balun
50Ω to 100Ω Balanced
Description
The BD0810N50100AHF is one of the world’s smallest and highest
performance, halogen free, low profile sub-miniature unbalanced to balanced
transformer targeted at the 900MHz ISM bands as well as the low band WCDMA /
GSM markets and designed specifically for differential inputs and output locations
on modern chipsets in an easy to use surface mount package. The
BD0810N50100AHF is ideal for high volume manufacturing and delivers higher
performance than traditional ceramic baluns. The BD0810N50100AHF has an
unbalanced port impedance of 50Ω and 100Ω balanced port impedance. The
balanced ports have equal amplitude (-3dB) with 180 degree phase differential. The
BD0810N50100AHF is available on tape and reel for pick and place high volume
manufacturing.
IMPORTANT: This balun must be used with a capacitor across the differential ports
as shown on Page 4 to optimize the performance.

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. Note that the BD0810N50100AHF
requires a 0201 size 1.6 pF capacitor across the differential (balanced) lines as shown in the diagram below for
the specific case of a 5 mil thick Polyamide substrate. This value may need to be adjusted slightly for different
substrate thicknesses and dielectric constants.
For 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.
