A compact energy harvesting system that converts RF/microwave signals to DC voltages between 4.2V...5.3V for mobile phone charging applications.
This RFD199A-PCB is a compact energy harvesting system converts RF/microwave signals to DC voltages between 4.2V...5.3V for mobile phone charging applications. The RF199A-PCB can convert 10MHz to 2.5GHz signals to a regulated DC output voltage that may be pulsed in low power conditions or continuous in high power conditions. The design consists of an RF-DC converter and a power management system that switches the DC output (VOUT) on when the internal voltage of the RF-DC converter and storage capacitor reaches 5.3V. The DC output (VOUT) switches off when the RF-DC converter voltage and storage capacitor voltage falls below 4.2V. When connected to an antenna, the module can extract power from wireless sources and produce an intermittent or continuous DC output voltage depending upon how much power is available. The VOUT lines are isolated so these modules may be tied together in parallel to improve output current for high power charging applications such as smartphones.
