So with the actual (most recent) NRF51822-QFAA shall we use BALF-NRF01D3 and not BAL-NRF01D3 ?

Dear all,

We will release the BALF-NRF01D3 to work with nRF51822-QFAA build code G0 and nRF51822-QFAB build code B0. Samples are available and mass production will start week 13.

Best Regards Richard

The ST balun, BAL-NRF01D3, will work only (world wide) with the build code C or older of the QFN packet. As of today, ST doesn't have an alternative for build code D. The balun can be used with build code D of Korean teleregulative approval isn't required.

The CSP uses another balun, the BAL-NRF02D3.

For the QFN version of the nRF51 series, a discrete balun is the standard solution. But this will not be suitable for the CSP as it's simply too large. That's why you'll find only the discrete balun for the QFN even if there are other options available.
