A cascode power cell for a power amplifier circuit includes a radio frequency signal input node, a radio frequency signal output node, and a plurality of sub-cells each including a first transistor having a collector coupled to the radio frequency signal output node, each of the plurality of sub-cells further including a second transistor having a collector coupled to an emitter of the first transistor at a connection node, and a base coupled to the radio frequency signal input node, the connection nodes for each of the plurality of sub-cells being electrically isolated from one another.
