Claim 7:
8. A method for processing a substrate in a processing chamber, comprising:
amplifying, using an amplifier comprising at least one of a gallium nitride (GaN) transistor or a gallium arsenide (GaAs) transistor, a power level of an input signal received from a power source;
outputting an amplified signal to a substrate support disposed in a processing volume of the processing volume to heat a substrate;
supplying a coolant to a cooling plate disposed on the amplifier to cool the amplifier during operation, wherein supplying the coolant comprises circulating the coolant through a plurality of cooling channels configured to allow the coolant to flow within the cooling plate; and
controlling flow of the coolant through the plurality of cooling channels using a controller in communication with the amplifier.
