Model B4859A53 Ultra Small Low Profile 0603 Balun to Balanced 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 and a 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. Detailed Electrical Specifications subject to change without notice.
