B4859A53 Anaren
Balun Transformer
MFG Part Number: B4859A53
Enlarge Photo
The B4859A53 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 B4859A53 is ideal for high volume manufacturing and is higher performance than traditional ceramic baluns. The B4859A53 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 integrated chipsets. The output ports have equal amplitude (-3dB) with 180 degree phase differential. The B4859A53 is available on tape and reel for pick and place high volume manufacturing.
