Model BD4859N50100AHF
Rev B
Ultra Low Profile 0404 Balun
50Ω to 100Ω Balanced
Description
The BD4859N50100AHF 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 UniBand II & III and the Japanese ISM band (4.9 GHz). The BD4859N50100AHF is
ideal for high volume manufacturing and delivers higher performance than traditional
ceramic baluns. The BD4859N50100AHF 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 integrated chipsets. The
output ports have equal amplitude (-3dB) with 180 degree phase differential. The
BD4859N50100AHF 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.
