CC85XX-CC2590EM reference design contains schematics and layout files for the CC85XX-CC2590EM module used in the PurePath Wireless CC85xxDK Development Kit. The reference design demonstrates good techniques for CC85XX-CC2590 decoupling and RF layout. For optimum RF performance: these parts should be copied accurately. This is a 4-layer reference design with a discrete balun and two antenna options: Either an SMA antenna connector designed for a single ended 50 ohm antenna or an inverted-F antenna (selectable by moving 0ohm resistor). The RF section is designed for operation in the 2.4GHz frequency band.
