The CC1101-CC1190EM 915 MHz reference design contains schematics and layout files for the CC1101-CC1190EM 915 MHz evaluation module. The reference design demonstrates good techniques for CC1101-CC1190 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 an SMA antenna connector designed for a single ended 50 ohm antenna. The RF section has been designed and characterized for operation in the 902-928 MHz frequency band.
