Description
The B0225J7575A00 is a low profile subꢀminiature balanced to unbalanced
transformer designed for differential inputs and output locations on next generation
wireless chipsets in an easy to use surface mount package covering the DVBꢀT,
DVBꢀC and DVBꢀS broadcast frequencies. The B0225J7575A00 is ideal for high
volume manufacturing and is higher performance than traditional wire wound and
lumped element baluns. The B0225J7575A00 has an unbalanced port impedance of
75ꢀ and a 75ꢀ balanced port impedance. This transformation enables single ended
signals to be applied to differential ports. The output ports have equal amplitude (ꢀ
3dB) with 180 degree phase differential. The B0225J7575A00 is available on tape
and reel for pick and place high volume manufacturing.
