P2110: 915 MHz RF Powerharvester™ Receiver
The Powercast P2110 Powerharvester receiver is an RF energy harvesting device that converts RF to DC. Housed in a compact SMD package, the P2110 receiver provides RF energy harvesting and power management for battery-free, micro-power devices. The P2110 converts RF energy to DC and stores it in a capacitor. When a charge threshold on the capacitor is achieved, the P2110 boosts the voltage to the set output voltage level and enables the voltage output. When the charge on the capacitor declines to the low voltage threshold the voltage output is turned off. A microprocessor can be used to optimize the power usage from the P2110 and obtain other data from the component for improving overall system operation.
