Classification: CPC H  Y | IPC H

Claim 10:
11. 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 has a second frequency;
a first filter coupled to the RF signal source, wherein the first filter is a low pass filter having a cutoff frequency between the first frequency and the second frequency, the first filter being configured to couple to a first end of a cable;
a second filter coupled to the first controller, wherein the second filter is a high pass filter having a cutoff frequency between the first frequency and the second frequency, the second filter being configured to couple to the first end of the cable;
an impedance matching network including an input, the input of the impedance matching network being configured to couple to a second end of the cable; 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;
a second controller coupled to the second end of the cable and configured to modify an impedance transformation performed by the impedance matching network based on the instructions; and
a fourth filter coupled between the second end of the cable and the second controller, wherein the fourth filter is a high pass filter having a cutoff frequency between the first frequency and the second frequency.
