Model BD2425J50100AHF
Rev C
Ultra Low Profile 0805 Balun
50Ω to 100Ω Balanced
Description
The BD2425J50100AHF 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 BD2425J50100AHF is ideal for high volume manufacturing and
is higher performance than traditional ceramic and lumped element baluns. The
BD2425J50100AHF has an unbalanced port impedance of 50Ω and a 100Ω
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 BD2425J50100AHF 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 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. 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.
