Product DatasheetP1110 – 915 MHz RF Powerharvester™ ReceiverDESCRIPTIONThe 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.APPLICATIONS• Wireless sensors - Industrial Monitoring - Smart Grid - Structural Health Monitoring - Defense - Building automation - Agriculture - Oil & Gas - Location-aware services Wireless trigger Low power electronics• •FUNCTIONAL BLOCK DIAGRAMFEATURES• • • • • • • • • • High conversion efficiency, >70% Low power consumption Configurable voltage output to support Li-ion and Alkaline battery recharging Operation from 0V to support capacitor charging Received signal strength indicator No external RF components required Internally matched to 50 ohms Wide operating range Operation down to -5 dBm input power Industrial temperature range RoHS CompliantGNDGNDGNDPIN CONFIGURATIONPowerharvester and Powercast are registered trademarks of Powercast Corporation.

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 will decrease as the voltage on the VOUT pin increase due to the fixed amount of power available. The P1110 monitors the voltage on the storage element and turns off VOUT when the element is fully charged. The P1110 does not monitor the charging current because it is typically much less than the maximum charge current of the storage element. When selecting a storage element, the leakage current must be strongly considered. Certain battery chemistries have higher leakage currents than others. It is recommended that the leakage current of the storage element be less than 1% per month. Higher leakage currents will result in using more of the harvested energy to replace the capacity lost due to leakage rather than replenishing the capacity. When no load is attached to the P1110, a minimum of 10uF is required on the VOUT pin. RSSI OPERATION (DOUT, DSET) The RSSI functionality allows the sampling of the received signal to provide an indication of the amount of energy being harvested. When DSET is driven high the harvested DC power will be directed to an internal sense resistor, and the corresponding voltage will be provided to the DOUT pin. The voltage on the DOUT pin can be read after a 20μs settling time. When the RSSI functionality is being used, the harvested DC power is not being stored. If the RSSI functionality is not used, the DOUT and DSET pins should be left as no connects. The DSET pin has an internal pull down. SETTING THE OUTPUT VOLTAGE (VOUT) The maximum voltage from the P1110 is set using the VSET, LI, or ALK pin. The LI pin can be directly connected to ground to set the maximum voltage to 4.2V, or the ALK pin+1 800-963-6538 P a g e |4Rev A –2010/04© 2010 Powercast Corporation, All rights reserved. Product DatasheetP1110 – 915 MHz RF Powerharvester™ Receivercan be directly connected to ground to set the maximum voltage to 3.3V. For custom voltage settings, the VSET pin can be used. Placing a resistor from VSET to ground will adjust the maximum output voltage. The resistor can be calculated using the following equation.R= 12.35M VOUT −MAX − 1.235 The DOUT pin can contain low-level analog voltage signals. If a long trace is connected to this pin, additional filtering capacitance next to the A/D converter may be required. Additional capacitance on this pin will increase the DSET delay time.LAYOUT CONSIDERATIONS When setting the output voltage, the resistor connected to the VSET pin should be as close as possible to the pin. No external capacitance should be added to this pin.The RFIN feed line should be designed as a 50Ω trace and should be as short as possible to minimize feed line losses. The following table provides recommended dimensions for 50Ω feed lines (CPWG) for different circuit board configurations.PCB Side ViewMaterial FR4 (εr = 4.2) FR4 (εr = 4.2)Thickness (H) 62 31Trace Width (S) 50 50Spacing (W) 9 20*All dimensions are in mils. The GND pins on each side of the RFIN pin should be connected to the PCB ground plane through a via located next to the pads under the receiver.Rev A –2010/04© 2010 Powercast Corporation, All rights reserved. +1 800-963-6538 P a g e |5Product DatasheetP1110 – 915 MHz RF Powerharvester™ ReceiverTYPICAL PERFORMANCE GRAPHSPowerharvester Efficiency vs. RFIN (dBm)TA = 25°C, unless otherwise noted.Powerharvester Efficiency vs. RFIN (mW)Powerharvester Efficiency vs. FrequencyPowerharvester Efficiency vs. FrequencyRev A –2010/04© 2010 Powercast Corporation, All rights reserved. +1 800-963-6538 P a g e |6Product DatasheetP1110 – 915 MHz RF Powerharvester™ ReceiverTYPICAL PERFORMANCE GRAPHSReceived Signal Strength Indicator vs. RFIN (dBm)TA = 25°C, unless otherwise noted.Received Signal Strength Indicator vs. RFIN (mW)Charge Current vs. RFIN (dBm)Charge Current vs. RFIN (mW)Rev A –2010/04© 2010 Powercast Corporation +1 800-963-6538 P a g e |7Product DatasheetP1110 – 915 MHz RF Powerharvester™ ReceiverTYPICAL APPLICATION CIRCUITPower Receiving AntennaVOUT RFINCommunication AntennaP1110 MicroprocessorDSET GND ALK DOUTRadio moduleSensorsRev A –2010/04© 2010 Powercast Corporation +1 800-963-6538 P a g e |8Product DatasheetP1110 – 915 MHz RF Powerharvester™ ReceiverMECHANICAL SPECIFICATIONSRev A –2010/04© 2010 Powercast Corporation, all rights reserved. +1 800-963-6538 P a g e |9Product DatasheetP1110 – 915 MHz RF Powerharvester™ ReceiverIMPORTANT NOTICEInformation furnished by Powercast Corporation (Powercast) is believed to be accurate and reliable.
