www.DataSheet.in Product Datasheet P1110 – 915 MHz RF Powerharvester™ Receiver DESCRIPTION The Powercast P1110 Powerharvester receiver is an RF energy harvesting device that converts RF to DC. Housed in a compact SMD package, the P1110 receiver provides RF energy harvesting and power management for battery and capacitor recharging. The P1110 converts RF energy to DC and provides the energy to the attached storage element. When an adjustable voltage threshold on the storage element is achieved, the P1110 automatically disables charging. A microprocessor can be used to obtain data from the component for improving overall system operation.

Any standard or custom 50Ω antenna may be used with the receiver. The P1110 has been optimized for operation in the 902-928MHz band but will operate outside this band with reduced efficiency. Contact Powercast for custom frequency requirements. The RF input must be isolated from ground. For antennas that are a DC short, a high-Q DC blocking capacitor should be added in series with the antenna. STORAGE SELECTION (VOUT) The P1110 is designed to charge an external storage element including batteries and capacitors. The output voltage from the P1110 will be set by the voltage of the storage element with a maximum set by the VSET, LI, or ALK pin. The P1110 will produce a charging current that will be dependent on the RF input power. The voltage on this pin can vary from 0V to 4.2V. The charging current for a fixed input RF power wi.
