3A412S

The 3A412S is a low profile balanced to unbalanced transformer designed for push pull amplifiers in an easy to use surface mount package for AMPS and GSM. These compact Xinger® surface mount baluns are ideal for high volume manufacturing and are more reliable and repeatable than traditional baluns. The 3A412S has an unbalanced port impedance of 50? and balanced port impedances of 12.5? to ground with a 25? 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 3A412S is available on tape and reel for pick and place high volume manufacturing.
