Ultra Low Profile 0805 Balun
50Ω to 200Ω Balanced
Description
The BD2425J50200AHF 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 GSM
frequencies. The BD2425J50200AHF is ideal for high volume manufacturing and is
higher performance than traditional ceramic and lumped element baluns. The
BD2425J50200AHF has an unbalanced port impedance of 50Ω and a 200Ω
balanced port impedance. This transformation enables single ended signals to be
applied to differential ports on modern semiconductors. The output ports have equal
amplitude (-3dB) with 180 degree phase differential. The BD2425J50200AHF is
available on tape and reel for pick and place high volume manufacturing.
