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.
