BD4859N50150AHF

Model BD4859N50150AHF Rev A Ultra Low Profile 0404 Balun 50Ω to 150Ω Balanced Description The BD4859N50150AHF is a low cost, low profile sub-miniature unbalanced to balanced transformer designed for differential inputs and output locations on modern chipsets in an easy to use surface mount package covering 802.11a UniBand II & III and the Japanese ISM band (4.9 GHz). The BD4859N50150AHF is ideal for high volume manufacturing and delivers higher performance than traditional ceramic baluns. The BD4859N50150AHF has an unbalanced port impedance of 50Ω and a150Ω balanced port impedance. This transformation enables single ended signals to be applied to differential ports on modern integrated chipsets. The output ports have equal amplitude (-3dB) with 180 degree phase differential. The BD4859N50150AHF 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 o and mechanical stability having X and Y thermal coefficient of expansion (CTE) of 17 ppm/ C. 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 With No DC Bias With DC Bias Plated thru hole to ground Plated thru hole to ground 3X .011 [0.28] .008 [0.20] 3X .011 [0.28] .014 [0.36] 3X .011 [0.28] SQ .020 [0.51] 3X Transmission Line .014 [0.36] .008 [0.20] .008 [0.20] .020 [0.51] 3X Transmission Line .020 [0.51] Circuit Pattern Circuit Pattern Footprint Pad (s) Footprint Pad (s) Solder Resist USA/Canada: Toll Free: Europe: Solder Resist Dimensions are in Inches [Millimeters] Mounting Footprint (315) 432-8909 (800) 411-6596 +44 2392-232392 Available on Tape and Reel for Pick and Place Manufacturing.
