Model BD1631J50100A00
Rev B
Ultra Low Profile 0805 Balun
50Ω to 100Ω Balanced
Description
The BD1631J50100Aoo is a low profile sub-miniature balanced to unbalanced
transformer designed for differential inputs and output locations on next generation
wireless chipsets in an easy to use surface mount package covering 802.11b+g+n,
GSM, DCS, PCS and UMTS. The BD1631J50100Aoo is ideal for high volume
manufacturing and is higher performance than traditional ceramic and lumped
element baluns. The BD1631J50100Aoo 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 semiconductors. The output
ports have equal amplitude (-3dB) with 180 degree phase differential. The
BD1631J50100Aoo is available on tape and reel for pick and place high volume
manufacturing.
