EVK30940 RF Evaluation Board - 868 MHz

The AEM30940 evaluation board is a printed circuit board (PCB) featuring all the needed components to operate the AEM30940 integrated circuit (IC). Please refer to the datasheet for all the useful details about the AEM30940 (Document DS AEM30940).

The AEM30940 evaluation board allows users to test the e-peas IC and analyze its performances in a laboratory-like setting. It includes two matching networks and rectifiers for a 50 Ω single-ended antenna. It allows easy connections to the RF energy harvester, the storage element and the low-voltage and high-voltage loads. It also provides all the configuration access to set the device in configuration modes described in the datasheet. The MPPT ratio is fixed at 50 % to optimize the rectifier efficiency. The control and status signals are available on standard pin headers, allowing users to wire for any usage scenario and evaluate the relevant performance.

The AEM30940 evaluation board is a plug and play, intuitive and efficient tool for making the appropriate decisions (component selection, operating modes) for the design of a highly efficient radio frequency powered subsystem in your target application. There are two designs of the AEM30940 evaluation board for RF harvesting. One is for the 868 MHz band and another for the 915 MHz band.
