Rf generator for generating a modulated frequency or an inter-modulated frequency

A radio frequency (RF) generator comprising:

• a first oscillator configured to generate a first RF signal;
• a second oscillator configured to generate a second RF signal;
• a first circuit coupled to the first oscillator to receive the first RF signal, wherein the first circuit is configured to apply a gain to the first RF signal to output a first adjusted RF signal;
• a second circuit coupled to the second oscillator to receive the second RF signal, wherein the second circuit is configured to apply a gain to the second RF signal to output a second adjusted RF signal;
• a combiner coupled to the first circuit to receive the first adjusted RF signal from the first circuit, wherein the combiner is coupled to the second circuit to receive the second adjusted RF signal from the second circuit, wherein the combiner is configured to add the first adjusted RF signal with the second adjusted RF signal to output a combined RF signal.

A method comprising:

• generating a first radio frequency (RF) signal;
• generating a second RF signal;
• applying a gain to the first RF signal to output a first adjusted RF signal;
• applying a gain to the second RF signal to output a second adjusted RF signal;
• and
• multiplying the first adjusted RF signal with the second adjusted RF signal to output a combined RF signal.

A method comprising:

• generating a first RF signal;
• generating a second RF signal;
• applying a gain to the first RF signal to output a first adjusted RF signal;
• applying a gain to the second RF signal to output a second adjusted RF signal;
• adding the first adjusted RF signal with the second adjusted RF signal to output a combined RF signal.
