Classification: CPC H | IPC H

Claim 13:
14. A radio frequency (RF) power amplifier device package, comprising:
a substrate; and
a first die, comprising a plurality of transistor cells, attached to the substrate at a source contact on a bottom surface of the first die and comprising top gate and drain contacts at a top surface of the first die opposite the bottom surface, wherein the top and bottom surfaces are external surfaces of the first die, and at least one of the top gate or drain contacts is electrically connected to a respective bottom gate or drain contact on the bottom surface by a respective conductive via structure that extends therebetween, and
wherein the top gate contact or the top drain contact is connected to one of impedance matching circuitry or harmonic termination circuitry at the top surface of the first die, and wherein the respective bottom gate or drain contact is connected to another of the impedance matching circuitry or harmonic termination circuitry at the bottom surface of the first die.
