Nano Profile 0404 Balun
50Ω to 75Ω Balanced
Description
The BD2425P5075AHF is a low cost, nano 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 BD2425P5075AHF
has been developed for placement inside highly integrated, over moldable
packaging solutions where overall module height is of greatest concern. Ideal for
high volume manufacturing and delivers higher performance than traditional ceramic
baluns in a sub 0.5mm height profile. The BD2425P5075AHF 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 BD2425P5075AHF 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/
o
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.
