Balun Transformers  
50to 25Balanced  
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 50and a balanced port impedances of 25to  
ground with 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 (-3 dB) with 180° phase differential.  
The 3A525 is available on tape and reel for pick and place high volume  
manufacturing.
