Xinger Balun  
50to 25Balanced  
Description  
The 3A425 is a low profile balanced to unbalanced transformer designed for push-  
pull amplifiers in an easy to use surface mount package covering GSM, D-AMPS  
and NMT900 applications. These compact Xinger® surface mount baluns are ideal  
for high volume manufacturing and are more reliable and repeatable than traditional  
baluns. The 3A425 has an unbalanced port impedance of 50Ω and balanced port  
impedances of 25Ω to ground with a 50Ω balance 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 3A425 is available on tape and reel for pick and place high volume  
manufacturing.
