Ultra Low Profile 0805 Balun
50 to 100 Balanced
Description
The B0310J50100AHF 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. The B0310J50100AHF is ideal for high
volume manufacturing and delivers higher performance than traditional wire wound
baluns. The B0310J50100AHF 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
B0310J50100AHF is available on tape and reel for pick and place high volume
manufacturing.
