Abstract
An arrangement and method for radio-frequency (RF) high power generation which compensate for a failed power amplifier module includes at least one power combiner having RF inputs and at least one RF output, and at least two power amplifier modules electrically connected to a respective input by at least one transmission line, and at least one RF switch formed by the at least one transmission line with a complex load electrically connected to the at least one RF switch.

An arrangement for radio-frequency (RF) high power generation, comprising:
- at least one power combiner having RF inputs and at least one RF output;
- at least two power amplifier modules electrically connected to a respective input by at least one transmission line comprising at least one externally controlled RF switch;
- a complex load electrically connected to the at least one externally controlled RF switch at a respective output of the at least two power amplifier modules;
- and
- a control unit configured to at least one of (i) detect a failure of a power amplifier module and (ii) control the at least one externally controlled RF switch.
A method for radio-frequency (RF) high power generation, the method comprising:
- detecting failure of at least one power amplifier module of at least two power amplifier modules electrically connected to a respective input of at least one power combiner, the at least two power amplifier modules being respectively and electrically connected to the at least one power combiner by at least one transmission line comprising at least one RF switch;
- and
- switching the at least one RF switch of the at least one power amplifier module which has failed to a mode without electrical connection of the at least one power combiner input to the at least one power amplifier module which has failed and with electrical connection of the at least one power combiner input to a complex load electrically connected to the at least one externally controlled RF switch at a respective output of the at least two power amplifier modules.
