1. A device comprising:
an antenna adapted to receive an RF signal comprising modulated data;
a demodulator adapted to demodulate the data from a first portion of the RF signal;
a power recovery unit adapted to convert a second portion of the RF signal to a DC power to power the device; and
a controller adapted to receive the RF signal from the antenna and generate the first and second portions of the RF signal in accordance with a ratio of impedance values of the demodulator and the power recovery unit at the output of the controller.
