Detailed Description for BAL-CW1250D3
Product Overview
BAL-CW1250D3 integrates the balanced/unbalanced transformation required in 2.4 GHz to 2.5 GHz signal paths. Its network is customized for CW1250, CW1150, CW1260 and CW1160 transceivers, presenting the stated 50 Ω nominal single-ended input / matched differential output relationship while reducing the number of external RF matching components. Only confirmed frequency, matching, package and application data is included; unavailable numerical limits are omitted.
This device is designed specifically for WLAN transceiver differential ports and avoids the area and tuning spread of a discrete LC matching network. The specified RFIC, package option and recommended PCB geometry are part of the matching solution, so a nearby ST balun code should not be substituted solely because it operates in the same general band.
