Model 3W512
Rev. B
Balun
50 to 12.5 Balanced
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 Xinger® surface 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 50Ω and balanced port impedances of
12.5Ω to ground with a 25Ω 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 3W512 is
available on tape and reel for pick and place high volume manufacturing.
