Model BD2425J5050A00

Rev B

Ultra Low Profile 0805 Balun

50Ω to 50Ω Balanced

Description

The BD2425J5050A00 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 BD2425J5050A00 is ideal for high volume manufacturing and is higher

performance than traditional ceramic and lumped element baluns. The

BD2425J5050A00 has an unbalanced port impedance of 50

Ω 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 BD2425J5050A00 is available on

tape and reel for pick and place high volume manufacturing.
