Description

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 XingerÒ 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 50W and balanced port impedances of 25W to ground with a 50W balance between outputs. This eases the matching of the push-pull amplifier's power transistors, which have low impedance levels.The output ports of the 3W525 have equal amplitude (-3dB) with 180 degree phase differential. The XingerÒ 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 3W525 is available on tape and reel for pick and place high volume manufacturing.
