Model BD2425P50100AHF
REV A
Nano Profile 0404 Balun
50 to 100 Balanced
Description
The BD2425P50100AHF is a low cost, nano 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
BD2425P50100AHF has been developed for placement inside highly integrated,
over moldable packaging solutions where overall module height is of greatest
concern. Ideal for high volume manufacturing and delivers higher performance than
traditional ceramic baluns in a sub 0.5mm height profile. The BD2425P50100AHF
has an unbalanced port impedance of 50& and a 100& 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 BD2425P50100AHF is available on tape and reel
for pick and place high volume manufacturing.
