Model BD4859L50150A00
Rev C
Ultra Small Low Profile 0603 Balun
50Ω to 150Ω Balanced
Description
The BD4859L50150A00 is an ultra-small low profile 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 802.11a Uni-
Band II and Uni-Band III and the Japanese ISM band (4.9GHz). The
BD4859L50150A00 is ideal for high volume manufacturing and is higher
performance than traditional ceramic baluns. The BD4859L50150A00 has an
unbalanced port impedance of 50Ω and a 150Ω 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 BD4859L50150A00 is available on tape and reel for
pick and place high volume manufacturing.
