Model BD1722N5050AHF
Rev A
Ultra Low Profile 0404 Balun
50 to 50 Balanced
Description
The BD1722N5050AHF is a low profile, low impedance sub-miniature
unbalanced to balanced transformer targeted at the GSM, CDMA, WCDMA and
UMTS designed for differential inputs and output locations on modern chipsets in an
easy to use surface mount package. The BD1722N5050AHF is ideal for high
volume manufacturing and delivers higher performance than traditional ceramic
baluns. The BD1722N5050AHF has an unbalanced port impedance of 50& and a
50& balanced port impedance. The output ports have equal amplitude (-3dB) with
180 degree phase differential. The BD1722N5050AHF is available on tape and reel
for pick and place high volume manufacturing.
