Ultra Low Profile 0404 Balun
50Ω to 50Ω Balanced
Description
The BD1416N5050A00 is a low profile sub-miniature unbalanced to balanced
transformer designed for differential inputs and output locations on modern chipsets
specifically in the GPS, GLONASS, WiMAX 1.5 (legacy TDM) and US DVB-H space
and in an easy to use surface mount package. The BD1416N5050A00 is ideal for
high volume manufacturing and delivers higher performance than traditional ceramic
baluns. The BD1416N5050A00 has an unbalanced port impedance of 50Ω and a
50Ω 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 BD1416N5050A00 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/
o
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.
