Model B0430J50100A00 Rev D Ultra Low Profile 0805 Balun 50Ω to 100Ω Balanced Description The B0430J50100A00 is a low cost, low profile sub-miniature unbalanced to balanced transformer designed specifically for differential inputs and output locations on next generation A to D and D to A Converter IC’s in an easy to use surface mount package, covering 400 MHz–3000 MHz. The B0430J50100A00 is ideal for high volume manufacturing and delivers higher performance than traditional wire wound baluns. The B0430J50100A00 has an unbalanced port impedance of 50Ω and a 100Ω balanced port impedance. This transformation enables single ended signals to be applied to differential ports. The output ports have equal amplitude (-3dB) with 180 degree phase differential. The B0430J50100A00 is available on tape and reel for pick and place high volume manufacturing. Note that for optimal performance, the B0430J50100A00 should be used with a 10 pF series capacitor on the unbalanced port as shown in p. 2 & 3.

Model B0430J50100A00 Rev D Mounting Configuration: This component requires a 0603 10 pF capacitor to be mounted in front of the unbalanced port (Pin 2) of the balun as shown in the drawing below for optimum performance. The capacitor should be placed as close as possible to the balun to minimize transmission line effects as shown in the suggested PCB footprint below. Note however, that 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. In order for Xinger surface mount components to work optimally, the proper impedance transmission lines must be used to connect to the RF ports. 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 o and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/ C.
