CC1125EM 868MHz ETSI Cat 1 Reference Design


Design files


The CC1125EM 868MHz ETSI Cat 1 reference design contains schematics and layout files for the CC1125EM 868MHz ETSI Cat 1 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 869.2-869.25 MHz frequency band and targets to meet compliance with ETSI Cat 1.
