The CC1125 169MHz EM reference design contains schematics and layout files for the CC1125EM 169MHz evaluation module. The reference design demonstrates good techniques for CC1125 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 for operation in the 169.4 to 169.6 MHz frequency band.
