Model 2425B50-100J
Preliminary
Xinger Balun
50Ω to 200Ω Balanced
Description
The 2425B50-100J 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.
The 2425B50-100J is ideal for high volume manufacturing and is higher
performance than traditional ceramic, and lumped element baluns. The 2425B50-
100J has an unbalanced port impedance of 50Ω and a 200Ω 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 2425B50-100J is available
on tape and reel for pick and place high volume manufacturing.
