CC85XX-CC2590 Antenna Diversity Reference Design contains schematics and layout files for the CC85XX-CC2590EM module which can be used with the PurePath Wireless CC85XXDK Development Kit. The reference design demonstrates good techniques for CC85XX-CC2590 decoupling and RF layout, including antenna switch and two SMA connectors for antenna diversity operation. This is supported in PurePath Wireless firmware version FW1.3.0 and higher available here. For optimum RF performance, decoupling and RF layout should be copied accurately. This is a 4-layer reference design, and the RF section is designed for operation in the 2.4GHz frequency band.
