Model BD2425N50200AHF
Rev A
Ultra Low Profile 0404 Balun
50 to 200 Balanced
Description
The BD2425N50200AHF 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. The
BD2425N50200AHF is ideal for high volume manufacturing and delivers higher
performance than traditional ceramic baluns. The BD2425N50200AHF has an
unbalanced port impedance of 50Ω and a 200Ω 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 BD2425N50200AHF 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 ceramic filled PTFE composites which possess excellent electrical
o
and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/ C.
An example of the PCB footprint used in the testing of these parts is shown below. An example of a DC-biased
footprint is also 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
