Abstract: One or more example relate, generally, to generating radio frequency (RF) signals. An apparatus may include a signal generator, an amplification stage, and a feedback control loop. The signal generator may generate a pulsed radio frequency (RF) signal at least partially responsive to a digital pulsed waveform defined by one or more commands. The amplification stage may amplify the pulsed RF signal. The feedback control loop may be coupled to the amplification stage to regulate a power level of respective steps of the pulsed RF signal.

Abstract: Radio frequency (RF) generators are disclosed. A RF generator may include a modulator configured to receive an arbitrary waveform and an RF carrier, and generate a pulsed radio frequency (RF). The arbitrary waveform may be generated via an analog signal generator external to the RF generator. Further, the RF generator may include an amplification stage configured to amplify the pulsed RF signal. RF generation systems and methods of generating a pulsed RF signal also disclosed.

Abstract: An apparatus includes an RF power amplifier with a controller and an impedance matching network. The RF power amplifier is configured to drive a load in electrical communication with the RF power amplifier. The impedance matching network is located electrically between the RF power amplifier and the load. The impedance matching network is configured to match an output impedance of the RF power amplifier and an impedance of the load. The impedance matching network includes a set of fixed value impedance matching circuits configured to provide different discrete values. The RF amplifier includes a variable DC power supply powering RF transistors to result in a variable output impedance for the amplifier. The controller selects an impedance matching circuit of the capacitor presets and/or the right setting for the variable DC supply that result in minimum reflected power to match the output impedance of the amplifier to the output load impedance.

Abstract: Radio frequency (RF) generators are disclosed. A RF generator may include an analog signal generator configured to generate a pulsed analog signal responsive to a digital pulsed waveform defined by one or more commands. The RF generator may also include a modulator configured to generate a pulsed radio frequency (RF) signal by modulating an RF carrier using the pulsed analog signal as a modulating signal. Further, the RF generator may include an amplification stage configured to amplify the pulsed RF signal output by the modulator. RF generation systems and methods of generating a pulsed RF signal also disclosed.
