Antenna Selection

[Jeff Finkelstein]

We plan on use the ST BAL-NRF01D3 balun for a PCB with both an nRF51822 and a nRF51922 on the same PCB separated by about 4 inches.

Should we use the PCB antenna as on the reference Dongle OR Development board OR should we think about a chip antenna for best performance?

On the nRF51822 webpage under the "downloads" tab in the "reference layout" section you can find the schematics with the balun: nRF51822 Reference Layout Files with STMicroelectronics BAL-NRF01D3 .
