Model BD1722J5050A00
Rev A
Ultra Low Profile 0805 Balun
50Ω to 50Ω Balanced
Description
The BD1722J5050A00 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, PCS,
DCS and UMTS frequencies. The BD1722J5050A00 is ideal for high volume
manufacturing and is higher performance than traditional ceramic, and lumped
element baluns. The BD1722J5050A00 has an unbalanced port impedance of 50Ω
and a 50Ω 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
BD1722J5050A00 is available on tape and reel for pick and place high volume
manufacturing.
