Ultra Low Profile 0805 Balun
50Ω to 150Ω Balanced
Description
The BD0810J50150AHF 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 frequency. The BD0810J50150AHF is ideal for high volume manufacturing
and is higher performance than traditional ceramic, and lumped element baluns. The
BD0810J50150AHF has an unbalanced port impedance of 50Ω and a 150Ω
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 BD0810J50150A00 is
available on tape and reel for pick and place high volume manufacturing.
