Convenient Package
The 3W525 is a low profile balanced to unbalanced transformer
designed for push-pull amplifiers in an easy to use surface
mount package for PCS, DCS, . These compact Xinger® surface
mount baluns are ideal for high volume manufacturing and are
more reliable and repeatable than traditional baluns. The
3W525 has an unbalanced port impedance of 50and
balanced port impedances of 25to ground with a 50balance
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 res ult of years of
research and development culminating with a solution so
unique, a patent is pending on the design approach. The 3W525
is available on tape and reel for pick and place high volume
manufacturing.
