Ultra Low Profile 0805 Balun
50 to 200 Balanced
Description
The   BD0810J50200AHF   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 BD0810J50200AHF is ideal for high volume manufacturing
and is higher performance than traditional ceramic and lumped element baluns. The
BD0810J50200A00 has an unbalanced port impedance of 50& and a 200&
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 BD0810J50200AHF is
available on tape and reel for pick and place high volume manufacturing.
