Are you looking for the antennas with one SMA connector pr. antenna or is it the radio with switch and SMA?

In that case it's probably easiest to just use a nRF52833-DK and an external 1 to 4 switch with SMA connectors.

Hi ketiljo,

how to connect the RF port between nrf52833-DK and our external antenna array.

We found there is a RF connector J1 but is for measuring RF signal by spectrum.

Can we also use this port to connect to our antenna board? how can we disconnect the external NFC and another on board antenna?

Can suggest any such sf switch compatible for nrf52833-DK?

Regards

Switch, maybe use 3x HMC849

Hi ketiljo,

Thank you for the information, 

Actually we need 4 SMA cannection from RF switch board to connect to 4 ports of the tester to measure RF performance.

What about the flashing procedure for board and firmware to enable direct test mode to support AOA and AOD.
