The CC1020EMX reference design contains schematics and layout files for the CC1020EMX. The CC1020EMX is designed for easy connection to most MCU evaluation modules for quick and easy application development and testing. The reference design demonstrates good techniques for CC1020 decoupling and RF layout. For optimum RF performance: these parts should be copied accurately. This is a 2-layer reference design with a discreete impedance match network for a single ended 50 ohm SMA antenna connector and an external antenna switch that is used to achieve optimum RF sensitivity. The design contains two different partlists for operation in either the 433 MHz or 868 MHz frequency band.
