The EN2223 from Energous Corporation is an RF-to-DC Wireless Power Receiver. It has been optimized for wireless charging applications where small implementation sizes and increased spatial freedom provide advantages over coil-based charging solutions. This receiver consists of matching networks (across all the ports), antennas, an RF-to-DC converter, and a clamper. It completely eliminates connectors or charging contacts, thereby resulting in a simplified charging process. This power receiver is available in a fully-sealed waterproof surface-mount package and is ideal for industrial IoT, automotive, health and safety, IoT and retail, defense and public safety, and consumer applications.
