Balanced

Description

The BD2425N5075AHF is a low cost, low profile sub-miniature unbalanced to

balanced transformer designed for differential inputs and output locations on modern

chipsets in an easy to use surface mount package. The BD2425N5075AHF is

halogen-free, ideal for high volume manufacturing and delivers higher performance

than traditional ceramic baluns. The BD2425N5075AHF has an unbalanced port

impedance of 50Ω and a 75Ω balanced port impedance. This transformation

enables single ended signals to be applied to differential ports on modern integrated

chipsets. The output ports have equal amplitude (-3dB) with 180 degree phase

differential. The BD2425N5075AHF is available on tape and reel for pick and place

high volume manufacturing.
