BD4859N50100AHF Datasheet, PDF (1/5 Pages) Anaren Microwave – Ultra Low Profile 0404 Balun

Model BD4859N50100AHF
Rev C
Ultra Low Profile 0404 Balun
50Ω to 100Ω Balanced
Description
The BD4859N50100AHF is a low cost, low profile sub-miniature unbalanced
to balanced transformer designed for differential inputs and output locations on
modern chipsets in an easy to use surface mount package covering 802.11a Uni-
Band II & III and the Japanese ISM band (4.9 GHz). The BD4859N50100AHF is
ideal for high volume manufacturing and delivers higher performance than traditional
ceramic baluns. The BD4859N50100AHF 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
BD4859N50100AHF is available on tape and reel for pick and place high volume
manufacturing.
