Hello,
Thank you for contacting NXP support.
The antenna diversity is implemented with two antenna’s which are separated and have offset orientation which allows the transceiver to statistically improve the chance to receive the RF signal outside the dynamic range of the system.
The KW36 has support only for one antenna, on the KW36-FRDM has a PCB F-antenna which can be bypassed to test via SMA connection.
We provide an schematic and design file that can be located on the FRDMKW36. This provide the information on how this is configured in the board.
Please let me know if there is anything else where I can help you.
