Model BD1722J5050A00 Rev A Ultra Low Profile 0805 Balun 50 to 50 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 50 and a 50 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. Detailed Electrical Specifications: Specifications subject to change without notice.

If this condition is not satisfied, insertion loss, Isolation and VSWR may not meet published specifications. All of the Xinger components are constructed from ceramic filled PTFE composites which possess excellent electrical and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/oC. An example of the PCB footprint used in the testing of these parts is shown below. An example of a DC-biased footprint is also shown below. In specific designs, the transmission line widths need to be adjusted to the unique dielectric coefficients and thicknesses as well as varying pick and place equipment tolerances.
