Model BD2425N50100AHF
Rev A
Ultra Low Profile 0404 Balun
50ꢀ to 100ꢀ Balanced
Description
The BD2425N50100AHF is a low cost, low profile subꢀminiature unbalanced
to balanced transformer designed for differential inputs and output locations on
modern chipsets in an easy to use surface mount package. The
BD2425N50100AHF is ideal for high volume manufacturing and delivers higher
performance than traditional ceramic baluns. The BD2425N50100AHF has an
unbalanced port impedance of 50ꢀ and a 100ꢀ 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 BD2425N50100AHF is available on tape and reel for
pick and place high volume manufacturing.
