Description
STMicroelectronics BAL-CW1250D3 is a balun
(balanced/unbalanced device) designed to
transform a single ended signal to differential
signals in WLAN application.
This BAL-CW1250D3, with low insertion losses in
the bandwidth 2400 MHz to 2500 MHz, has been
customized for CW1250, CW1150, CW1260,
CW1160 transceiver. The differential output
embeds an integrated matching network adapted
to the transceiver.
The BAL-CW1250D3 has been designed using
STMicroelectronics IPD (integrated passive
device) technology on non-conductive glass
substrate to optimize RF performance.
