Rev D
Ultra Low Profile 0404 Balun
50Ω to 75Ω Balanced
Description
The BD4859N5075A00 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 covering 802.11a Uni-Band II &
III and the Japanese ISM band (4.9 GHz). The BD4859N5075A00 is ideal for high
volume manufacturing and delivers higher performance than traditional ceramic
baluns. The BD4859N5075A00 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 BD4859N5075A00 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
