Classification: CPC H | IPC H

Claim 16:
17. A method of operating a power amplifier, the method comprising:
amplifying, with a main amplifier, a first portion of a received signal;
providing a first output from the main amplifier to a first impedance inverter;
receiving, at a first combining node, a first signal from the first impedance inverter;
amplifying, with a first peaking amplifier arranged in parallel with the main amplifier, a second portion of the received signal;
receiving, at the first combining node, a second signal from the first peaking amplifier, with the first peaking amplifier being directly connected to the first combining node;
providing a first combined signal from the first combining node to a second impedance inverter;
providing an output signal from the second impedance inverter to a second combining node;
amplifying, with a second peaking amplifier arranged in parallel with the first peaking amplifier, a third portion of the received signal;
providing an output from the second peaking amplifier to a third impedance inverter;
receiving, at the second combining node, a third signal from the third impedance inverter; and
outputting, by the main amplifier, an amount of maximum power or current that differs by at least 20% from an amount of maximum power or current output by the first peaking amplifier and outputting, by the main amplifier, the amount of maximum power or current that differs by at least 20% from an amount of maximum power or current output by the second peaking amplifier.
