WIRELESS CONTROL DEVICE

摘要

A wireless control device may include an antenna and a power harvester configured to generate power for the device from a radio frequency signal incident on the antenna. The device may further include an upconverter stage comprising a first port to receive a control signal to be upconverted and a second port to receive the incident radio frequency signal and to output the upconverted control signal at upper and lower sideband frequencies. The antenna may be coupled to the second port.
