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.
