Ultra Low Profile 0805 Balun
75Ω to 75Ω Balanced
Description
The B0225J7575AHF is a low profile sub-miniature balanced to unbalanced
transformer designed for differential inputs and output locations on next generation
wireless chipsets in an easy to use surface mount package covering the DVB-T,
DVB-C and DVB-S broadcast frequencies. The B0225J7575AHF is ideal for high
volume manufacturing and is higher performance than traditional wire wound and
lumped element baluns. The B0225J7575AHF has an unbalanced port impedance
of 75Ω and a 75Ω balanced 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 B0225J7575AHF 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.
