Model B0430J50100A00
Rev E
Ultra Low Profile 0805 Balun
50Ω to 100Ω Balanced
Description
The B0430J50100A00 is a low cost, low profile sub-miniature unbalanced to
balanced transformer designed specifically for differential inputs and output
locations on next generation A to D and D to A Converter IC’s in an easy to use
surface mount package, covering 400 MHz–3000 MHz. The B0430J50100A00 is
ideal for high volume manufacturing and delivers higher performance than traditional
wire wound baluns. The B0430J50100A00 has an unbalanced port impedance of
50and a 100balanced port impedance. This transformation enables single
ended signals to be applied to differential ports. The output ports have equal
amplitude (-3dB) with 180 degree phase differential. The B0430J50100A00 is
available on tape and reel for pick and place high volume manufacturing.
Note that for optimal performance, the B0430J50100A00 should be used with a 10
pF series capacitor on the unbalanced port as shown in p. 2 & 3.

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.
This component requires a 10 pF capacitor to be mounted in front of the unbalanced port (Pin 2) of the balun as
shown in the drawing below for optimum performance. The capacitor should be placed as close as possible to the
balun to minimize transmission line effects as shown in the suggested PCB footprint below.
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.
