Model BD2425N5075A50
Rev A
Ultra Low Profile 0404 Balun
50Ω to 75Ω Balanced
Description
The BD2425N5075A50 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 BD2425N5075A50 is ideal
for high volume manufacturing and delivers higher performance than traditional
ceramic baluns. The BD2425N5075A50 has an unbalanced port impedance of 50Ω
and a 75Ω 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
BD2425N5075A50 is available on tape and reel for pick and place high volume
manufacturing.
