Abstract
Provided is a generator including a power amplifier, at least one sampler, an RF output, a signal generator, a controller including a digital control portion and an analogue control portion, an analogue feedback path between the at least one sampler and the controller enabling an analogue signal representation of a signal to be provided to the controller, and a digital feedback path between the at least one sampler and the controller enabling a digital signal representation of the signal to be provided to the controller. The controller is configured to adjust the RF signal at the RF output from a first state into a second state based on the analogue signal representation and/or the digital signal representation.
Claims23
A method for operating a generator, comprising:
- generating, using an RF power stage, an RF output signal based on an RF input signal generated by a signal generator;
- sampling, using at least one sampler, a radio frequency (RF) signal at an output of the RE power stage;
- generating a digital signal representation of the signal from the at least one sampler and providing the digital signal representation to a controller via a digital feedback path between the at least one sampler and the controller;
- generating an analogue signal representation of the signal from the at least one sampler and providing the analogue signal representation to the controller via an analogue feedback path between the at least one sampler and the controller, wherein one or both of a digital control portion and an analogue control portion of the controller are configured to control at least the RF power stage and/or the signal generator;
- and
- adjusting, using the controller, the RF output signal from a first state into a second state based on the analogue signal representation and/or the digital signal representation, wherein the at least one sampler provides:
- (i) a forward RF signal and a reflected RF signal, or
- (ii) a voltage si current signal,
- to the analogue feedback path and/or the digital feedback path.
