Model 3W512  
Rev. B  
Balun  
50to 12.5Balanced  
Description  
The 3W512 is a low profile balanced to unbalanced transformer designed for push-  
pull amplifiers in an easy to use surface mount package for PCS, DCS, and UMTS.  
These compact Xingersurface mount baluns are ideal for high volume  
manufacturing and are more reliable and repeatable than traditional baluns. The  
3W512 has an unbalanced port impedance of 50and balanced port impedances of  
12.5to ground with a 25balance between outputs. This eases the matching of  
the push-pull amplifier’s power transistors, which have low impedance levels. The  
output ports have equal amplitude (-3dB) with 180 degree phase differential. The  
Xinger  
balun is a result of years of research and development culminating with a  
solution so unique, a patent is pending on the design approach. The 3W512 is  
available on tape and reel for pick and place high volume manufacturing.
