Description
The 2425B50-50C 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 2425B50-50C is ideal for high volume manufacturing and is higher performance
than traditional ceramic baluns. The 2425B50-50C 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 2425B50-50C is available on tape and reel for pick and place high
volume manufacturing.
