nRF51822 certified baluns

[Cliff Hirsch]

Exactly what baluns are known to work with the nRF51822. I believe there is the STMicro balun and am uncertain about the status of the Johansen balun. Is there a list of preferred baluns?

Hello,

Currently, only the ST baluns are certified/recommended for the nRF51822. For the nRF51822 QFN package, the BAL-NRF01D3 should be used. For the nRF51822 WLCSP package, the BAL-NRF02D3 should be used.

Edit: There are now more baluns that can be used:

• QFN: Johanson Technology 2450BM14E0003
• WLCSP: Cyntec TBL-14-11-245-LR

The list of the baluns to be used can be found on the nRF51822 webpage --> "Development tools and software" tab

Hi,

which disadvantages would I expect when using the BAL-NRF02D3 with the nRF51822 QFN?

Thanks, Omar
