Rev E
Ultra Low Profile 0404 Balun
50Ω to 75Ω Balanced
Description
The BD2425N5075A00 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 BD2425N5075A00 is ideal
for high volume manufacturing and delivers higher performance than traditional
ceramic baluns. The BD2425N5075A00 has an unbalanced port impedance of 50Ω
and a 75Ω 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
BD2425N5075A00 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
and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/oC.
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.
