Rev A
Ultra Low Profile 1608 Balun
50 to 200 Balanced
Description
The B0205F50200AHF is a low profile sub-miniature balanced to unbalanced
transformer designed for differential input locations on data conversion devices (A to
D converters). In an easy to use surface mount package covering 200 MHz to 500
MHz and superior CMRR performance, this transformer is optimized to offer
improved SFDR management during operation of the data converter device. The
B0205F50200AHF is ideal for high volume manufacturing and is higher performance
and   smaller   form   factor   than   traditional   wire   wound   transformers.   The
B0205F50200AHF has an unbalanced port impedance of 50 and a 200 balanced
port impedance. This transformation enables single ended signals to be applied to
differential ports on the data converter devices. The output ports have equal
amplitude (-3dB) with 180 degree phase differential. The B0205F50200AHF is
available on tape and reel for pick and place high volume manufacturing.
