CC1121EM 868/915 MHz Reference Design

1 января 2018

The CC1121 868/915MHz EM reference design contains schematics and layout files for the CC1121EM 868/915MHz evaluation module. The reference design demonstrates good techniques for CC1121 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 863 to 870 MHz band (EU) and 902 to 928MHz (US) frequency bands.
