Claim 5:
6. An RF generator comprising:
an excitation amplifier circuit configured to generate an RF signal;
a first power amplifier circuit and a second power amplifier circuit configured to amplify power of the RF signal generated by the excitation amplifier circuit;
a combiner to which outputs of the first and second power amplifier circuits are input; and
a control circuit,
wherein the combiner is the Wilkinson-type combiner of claim 1,
each of the outputs of the first and second power amplifier circuits is input to a corresponding one of the first input terminal and the second input terminal, and
the control circuit receives the control signal from the determination circuit to block input of the RF signals to the first and second input terminals.
