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.
FEATURES
• 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 Compliant
APPLICATIONS
• Wireless sensors
- Industrial Monitoring
- Smart Grid
- Structural Health Monitoring
- Defense
- Building automation
- Agriculture
- Oil & Gas
- Location-aware services
• Wireless trigger
• Low power electronics

Product Datasheet
P1110 – 915 MHz RF Powerharvester™ Receiver
can 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
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 View
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.

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.
