Model BD1722N5050AHF
Rev A
Ultra Low Profile 0404 Balun
50Ω to 50Ω Balanced
Description
The BD1722N5050AHF is a low profile, low impedance sub-miniature
unbalanced to balanced transformer targeted at the GSM, CDMA, WCDMA and
UMTS designed for differential inputs and output locations on modern chipsets in an
easy to use surface mount package. The BD1722N5050AHF is ideal for high
volume manufacturing and delivers higher performance than traditional ceramic
baluns. The BD1722N5050AHF 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 BD1722N5050AHF 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. 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.
