Anaren BD2425N100ATI Impedance matched ultra low profile 0404 balun for ti cc2530 chipset Datasheet

Model BD2425N100ATI
Rev A
Impedance Matched Ultra Low profile 0404
Balun for TI CC2530 chipset
(Anaren Application Note Ann-2004)
Description
The BD2425N100ATI is a low cost, low profile sub-miniature unbalanced to
balanced transformer specifically designed for differential inputs and output
locations Texas Instruments CC2530 SoC Solution in an easy to use surface
mount package. The BD2425N100ATI is ideal for high volume
manufacturing and delivers higher performance than traditional ceramic
baluns. This transformation enables single ended signals to be applied to
differential ports on the CC2530. The output ports have equal amplitude (3dB) with 180 degree phase differential. The BD2425N100ATI 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.
