BD2425NNRF Datasheet, PDF (1/4 Pages) Anaren Microwave – Ultra Low Profile 0404 Balun For nRF24L01 and nRF24L01

Model BD2425NnRF
Rev B
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 50Ω 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.
