Patent ID: 7512387

Claim:
A method of controlling an output power supplied to a load from a radio frequency amplifier system, the method comprising: allocating a total output power from the amplifier system between a first portion supplied to the load and a second portion supplied to a dissipative element; determining a value representing a forward power supplied from the amplifier system to the load or determining a value representing a reflected power reflected from the load; determining a first control value based a predetermined forward power value and the value representing the forward power or based on a predetermined reflected power value and the value representing the reflected power; determining a value representing a power supplied to the dissipative element; determining a second control value based on a predetermined dissipated power value and the value representing the power supplied to the dissipative element; controlling an amplifying member of the amplifier system that supplies power to the load based on one of the control values; and controlling a current supply that supplies an output current to the amplifying member based on one of the control values.
