Ultra Low Profile 1608 Balun
50 to 50 Balanced
Description
The BD0205F5050AHF is a low profile sub-miniature balanced to unbalanced
transformer designed for differential input locations on data conversion devices such
as A to D and D to A converters. In an easy to use surface mount package covering
75 MHz to 1000 MHz and with CMRR performances over 2x that of the incumbent
wire wound products, this transformer is optimized to offer improved SFDR
management during operation of the data converter device. The BD0205F5050AHF
is ideal for high volume manufacturing and is higher performance and smaller form
factor than traditional wire wound transformers. The BD0205F5050AHF has an
unbalanced port impedance of 50 and a 50 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 BD0205F5050AHF is available on tape and reel for
pick and place high volume manufacturing.
