Xinger Balun

50Ω to 25Ω Balanced

Description

The 3A325 is a low profile balanced to unbalanced transformer designed for push-

pull amplifiers in an easy to use surface mount package for NMT450 and TV

broadcast applications. These compact Xinger® surface mount baluns are ideal for

high volume manufacturing and are more reliable and repeatable than traditional

baluns. The 3A325 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 3A325 is available on tape and reel for pick and place high volume

manufacturing.
