Model BD4859N50100A00
Rev D
Ultra Low Profile 0404 Balun
50Ω to 100Ω Balanced
Description
The BD4859N50100A00 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 covering 802.11a Uni-Band II &
III and the Japanese ISM band (4.9 GHz). The BD4859N50100A00 is ideal for high
volume manufacturing and delivers higher performance than traditional ceramic
baluns. The BD4859N50100A00 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 BD4859N50100A00
is available on tape and reel for pick and place high volume manufacturing.
