B0225J7575AHF
Rev E
Ultra Low Profile 0805 Balun
75Ω to 75Ω Balanced
Description:
The B0225J7575AHF is a low profile sub-miniature 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 DVB-T, DVB-C and DVB-S broadcast frequencies. The
B0225J7575AHF is ideal for high volume manufacturing and is higher
performance than traditional wire wound and lumped element baluns. The
B0225J7575AHF has an unbalanced port impedance of 75Ω and a 75Ω
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 B0225J7575AHF is available on
tape and reel for pick and place high volume manufacturing.
