1. A system, comprising:
a radio frequency (RF) signal source configured to output an RF signal having a first frequency;
a first controller configured to generate a first data signal encoding instructions, wherein the first data signal is modulated with a carrier signal having a second frequency and the second frequency does not overlap the first frequency;
a first filter coupled to the RF signal source and configured to inhibit transmissions of the first data signal through the first filter and allow transmissions of the RF signal through the first filter, the first filter being configured to couple to a first end of a cable;
a second filter coupled to the first controller and configured to inhibit transmissions of the RF signal through the second filter and allow transmissions of the first data signal through the second filter, the second filter being configured to couple to the first end of the cable;
an impedance matching network configured to couple to a second end of the cable;
a third filter coupled between the second end of the cable and the impedance matching network, wherein the third filter is configured to inhibit transmissions of the first data signal through the third filter and allow transmissions of the RF signal through the third filter; and
a first electrode in a cavity configured to receive a load, wherein the first electrode is coupled to an output of the impedance matching network and configured to radiate electromagnetic energy into the cavity as a result of receiving the RF signal.
