A RF power transistor is configured so that it can be divided up into 2 or more parts. Typically the transistors are made up of a large number of cells (smaller transistors) that are all connected in parallel. This configuration keeps the input side of the device separated into parts that can be biased and or RF driven separately. This allows part of the device to be biased off which results in better efficiency when the transistor is backed off for linear operation.
