Model BD2327N50100AHF
Rev D
Ultra Low Profile 0404 Balun
50Ω to 100Ω Balanced
The BD2327N50100AHF 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
BD2327N50100AHF is ideal for high volume manufacturing and delivers higher
performance than traditional ceramic baluns. The BD2327N50100AHF has an
unbalanced port impedance of 50Ω and a 100Ω 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 BD2327N50100AHF is available on tape and reel for
pick and place high volume manufacturing.
