Rev B
Ultra Low Profile 0404 Balun
50Ω to 50Ω Balanced
Description
The BD2425N5050AHF is a low profile, low impedance sub-miniature
unbalanced to balanced transformer designed for differential inputs and output
locations on modern chipsets targeted at 802.11 b+g, MIMO b+g, Bluetooth, Zigbee,
ULPR and ISM band Applications in an easy to use surface mount package. The
BD2425N5050AHF is ideal for high volume manufacturing and delivers higher
performance than traditional ceramic baluns. The BD2425N5050AHF has an
unbalanced port impedance of 50Ω and a 50Ω balanced port impedance.. The
output ports have equal amplitude (-3dB) with 180 degree phase differential. The
BD2425N5050AHF 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.
