Model BD1222J50200AHF
Rev A
Ultra Low Profile 0805 Balun
50Ω to 200Ω Balanced
Description
The BD1222J50200AHF 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
DCS, PCS, UMTS and CDMA frequencies. The BD1222J50200AHF is ideal for high
volume manufacturing and is higher performance than traditional ceramic and
lumped element baluns. The BD1222J50200AHF has an unbalanced port
impedance of 50 and a 200 balanced port impedance. This transformation
enables single ended signals to be applied to differential ports on modern
semiconductors. The output ports have equal amplitude (-3dB) with 180 degree
phase differential. The BD1222J50200AHF 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.
