e-peas EVK30940 868MHz Evaluation Board
e-peas EVK30940 868MHz Evaluation Board is a complete reference circuit based on the AEM30940 RF energy harvesting IC. The AEM30940 is an integrated Ambient Energy Manager (AEM) that can extract DC power from a piezo generator, a microturbine generator, or any other high-frequency RF input. The device simultaneously stores energy in a rechargeable element and supplies the system with two independent regulated voltages.
The EVK30940 868MHz evaluation board allows users to demonstrate the features of the AEM30940 and analyze performances in a laboratory-like setting. This board includes two matching networks and rectifiers for a 50Ω single-ended antenna. The EVK30940 allows for easy connection to the RF energy harvester, the storage element, and the low-voltage and high-voltage loads. 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 EVK30940 evaluation board is a plug-and-play tool powered by piezo or microturbine energy harvesting in the target application. This board is available in 76mm x 49mm dimensions.
