The CC1101EM reference design contains schematics and layout files for the CC1101EM module used in development kits. The reference design demonstrates good techniques for CC1101 decoupling and RF layout. For optimum RF performance, these parts should be copied accurately. This is a 2-layer reference design with a discrete balun and SMA antenna connector designed for a single ended 50 ohm antenna. The RF section is designed for operation in the 315 MHz and 433 MHz frequency bands.
