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.
