Patent attributes
A novel RF power amplifier integrated circuit (PA IC), unit cell, and method for amplifying RF signals are disclosed. One embodiment of a PA IC includes at least two linear arrays comprising transistor device units, and at least one linear array comprising capacitors. The transistor device units include source nodes that are jointly coupled to a source bus, and selected gate nodes that are jointly coupled to a gate bus. First electrodes of the capacitors are also jointly coupled to the source bus, and second electrodes of the capacitors are jointly coupled to the gate bus. Each linear array comprising capacitors is disposed between at least two linear arrays comprising transistor device units. In one embodiment, the PA IC includes unit cells. In some embodiments, each unit cell comprises two transistor device units and one or more capacitors. The capacitors are disposed between the transistor device units. The unit cells are disposed in linear arrays so that the transistor device units are disposed in linear arrays and the capacitors are disposed in linear arrays.
