Abstract
Power amplifiers such as multi-path power amplifiers, systems employing such amplifiers, and methods of implementing amplifiers and amplifier systems are disclosed herein. In one example embodiment, a multi-path power amplifier includes a first semiconductor die with an integrated first transistor having a first source-to-drain pitch, and a second semiconductor die with an integrated second transistor having a second source-to-drain pitch, where the second source-to-drain pitch is smaller than the first source-to-drain pitch by at least 30 percent. In another example embodiment, a Doherty amplifier system includes a first semiconductor die with a first physical die area to total gate periphery ratio, and a second semiconductor die with a second physical die area to total gate periphery ratio, where the second physical die area to total gate periphery ratio is smaller than the first physical die area to total gate periphery ratio by at least 30 percent.
