Claim 0:
1. A radio frequency (RF) power amplifier device package, comprising:
a substrate;
a first die, comprising a plurality of transistor cells, attached to the substrate at a bottom surface of the first die and comprising top gate or drain contacts on 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 at least one respective bottom gate or drain contact on the bottom surface of the first die by at least one respective conductive via structure that extends therebetween; and
an integrated interconnect structure on the first die opposite the substrate, the integrated interconnect structure comprising a first contact pad on the top gate contact or the top drain contact of the first die, and at least one second contact pad connected to a package lead, a contact of a second die, impedance matching circuitry, and/or harmonic termination circuitry.
