Model 3A525
Rev. A
Balun Transformers 50 to 25 Balanced
Description
The 3A525 is a low profile balanced to unbalanced transformer in an easy to use surface mount package covering Japanese PDC, DCS and PCS receive push-pull amplifier and mixer applications. The 3A525 has an unbalanced impedance of 50 and a balanced port impedances of 25 to ground with 50 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 (-3 dB) with 180° phase differential. The 3A525 is available on tape and reel for pick and place high volume manufacturing.
