Cable arrangement for heating system

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;
• 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;
• a direct current (DC) power source configured to output a DC signal;
• and
• a fifth filter, wherein the fifth filter is coupled between the DC power source and the first end of the cable, and the fifth filter is configured to inhibit transmissions of the first data signal and the RF signal through the fifth filter and to allow transmissions of the DC signal to pass through the fifth filter.

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.
