Model BD2425J5050A00
Rev B
Ultra Low Profile 0805 Balun
50Ω to 50Ω Balanced
Description
The BD2425J5050A00 is a low profile sub-miniature balanced to unbalanced
transformer designed for differential inputs and output locations on next generation
wireless chipsets in an easy to use surface mount package covering 802.11b+g+n.
The BD2425J5050A00 is ideal for high volume manufacturing and is higher
performance than traditional ceramic and lumped element baluns. The
BD2425J5050A00 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 semiconductors. The output ports have equal amplitude
(-3dB) with 180 degree phase differential. The BD2425J5050A00 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.
