A wireless control device is described that single chip passive wireless control integrated circuit device. The device is coupled to an antenna configured to receive a radio signal and comprises a radio frequency transceiver circuit fabricated on a semiconductor substrate of an integrated circuit device and configured to extract information from the radio signal and a processor fabricated on the semiconductor substrate and configured to receive the information extracted from the radio signal and to respond to a command encoded in the information. A FET fabricated on the substrate operates as a switch and has a gate controlled by the processor. The FET can be configured to transmit an activation current provided to the integrated circuit device to an output of the integrated circuit device. The output may drive an actuator.
