Description

The BD2130J5050AHF is a low profile sub-miniature 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 802.11b+g+n.

The BD2130J5050AHF is ideal for high volume manufacturing and is higher

performance

than

traditional

ceramic

and

lumped

element

baluns.

The

BD2130J5050AHF has an unbalanced port impedance of 50Ω and a 50Ω balanced

port impedance. This transformation enables single ended signals to be applied to

differential ports on modern semiconductors. The output ports have equal amplitude

(-3dB) with 180 degree phase differential. The BD2130J5050AHF is available on

tape and reel for pick and place high volume manufacturing.
