Balun Transformers

50Ω to 25Ω 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 50Ω and a balanced port impedances of 25Ω to

ground with 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 (-3 dB) with 180° phase differential.

The 3A525 is available on tape and reel for pick and place high volume

manufacturing.
