Ultra Low Profile 0404 Balun

to 100

Balanced

Description

The BD3150N50100AHF 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 the MMDS and

the low end of the UWB frequency range. The BD3150N50100AHF is ideal for high

volume manufacturing and delivers higher performance than traditional ceramic

baluns. The BD3150N50100AHF 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 BD3150N50100AHF

is available on tape and reel for pick and place high volume manufacturing.
