Rev A
Ultra Low Profile 0404 Balun
for TI transceiver CC2500
50Ω to 127+j34Ω Balanced
(Anaren Application Note Ann-2003)
Description
The BD2425N50ATI is a low cost, low profile sub-miniature unbalanced to
balanced transformer designed for differential inputs and output locations on modern
chipsets in an easy to use surface mount package. The BD2425N50ATI is ideal for
high volume manufacturing and delivers higher performance than traditional ceramic
baluns. The BD2425N50ATI has an unbalanced port impedance of 50Ω and 127+
j34Ω balanced port impedance. This transformation enables single ended signals to
be applied to differential ports on modern integrated chipsets. The output ports have
equal amplitude (-3dB) with 180 degree phase differential. The BD2425N50ATI is
available on tape and reel for pick and place high volume manufacturing.
