| Model BD2425NNRFA00 Rev A Ultra Low Profile 0404 Balun For nRF24L01 and nRF24L01+ (Anaren Application Note Ann-3001) Description The BD2425NnRF is a low cost, low profile sub-miniature unbalanced to balanced transformer designed for differential inputs and output, tuned to provide optimal performance in tandem with the Nordic Semiconductor nRF24L01 and nRF24L01+. The BD2425NnRF is ideal for high volume manufacturing and delivers higher performance than a discrete implementation. The BD2425NnRF has an unbalanced port impedance of 50 and matched balanced port impedance when used in the specified matching network, which is the conjugate match of the nRF24L01 and nRF24L01+ devices. This transformation enables single ended signals to be applied to differential ports on the nRF24L01 and nRF24L01+. The BD2425NnRF 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 3X .011 [0.29] .008 [0.21] 3X .011 [0.29] Plated thru hole to ground .014 [0.36] .020 [0.50] .008 [0.21] 3X Transmission Line .020 [0.50] Circuit Pattern Footprint Pad (s) Solder Resist Dimensions are in Inches [Millimeters] Mounting Footprint USA/Canada: Toll Free: Europe: (315) 432-8909 (800) 411-6596 +44 2392-232392 Available on Tape and Reel for Pick and Place Manufacturing.
