Patent ID: 6909324

Claim:
A solid state power amplifier device comprising: a first amplifier section having a power amplifier stage connected to at least one solid state amplifier for receiving a first input signal therefrom and for providing output power via an output node; a second amplifier section having a plurality of amplifier lines each having a plurality of solid state amplifiers and connected to a divider, wherein a signal inputted within the divider is divided into a plurality of signals and each one of the plurality of signals is fed to a respective one of the plurality of amplifier lines for providing output power from a respective output node of each of the plurality of amplifier lines, wherein the output power provided by each of the plurality of amplifier lines is less than the output power provided by the power amplifier stage; and a coupler for receiving an input signal and dividing the same into the first and second input signals, wherein the first amplifier section further includes an isolator connected to the power amplifier stage and wherein each of the plurality of amplifier lines further includes an isolator connected in series to the plurality of solid state amplifiers.
