RF wireless power transmitted by the PowerSpot transmitter is received by two receiver sticks with LEDs. The TX91503 PowerSpot transmitter broadcasts an RF signal in the unlicensed 915 MHz industrial, scientific […]
How do you make an RF energy harvester even better?
For Powercast, whose Powerharvester receiver (PCC110) has been deployed in industrial and commercial systems for seven years, today’s answer is reduce the footprint and volume. The company’s new PCC114 receiver chip’s footprint (1 x 0.6 x 0.3 mm) is seven times smaller than the PCC110 (2 x 2.1 x 0.9 mm) and has 20 times […]
