Regarding nRF51822 Range Extend

[Nazmus Sakib]

Hi All.

For my project I need a very long range BLE Communication. Don't know if its possible to get a range close to 1 Mile LoS. But my goal is to meet max possible range.

I made a custom Board using nRF51822 and with good RF tuning I have achieved close to 200 Feet LoS range using Chip Antenna. Now I like to have your advise regarding implementing RF Power Amp to get a max possible range.

Ca anyone share a such reference design of nRF51822 with PA implementation? Or any good PA chips?

Thanks in advance.

Awaiting for your revert.

Regards.
