Model BD2130J5050A00
Rev A
Ultra Low Profile 0805 Balun
50Ω to 50Ω Balanced
Description
The BD2130J5050A00 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 BD2130J5050A00 is ideal for high volume manufacturing and is higher
performance than traditional ceramic and lumped element baluns. The
BD2130J5050A00 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 BD2130J5050A00 is available on
tape and reel for pick and place high volume manufacturing.
