Abstract: Leadless power amplifier (PA) packages having topside termination interposer (TTI) arrangements, and associated fabrication methods, are disclosed. Embodiments of the leadless PA package include a base flange, a first set of interposer mount pads, a first RF power die, a package body. The first RF power die is attached to a die mount surface of the base flange and electrically interconnected with the first set of interposer mount pads. The TTI arrangement is electrically coupled to the first set of interposer mount pads and projects therefrom in the package height direction. The package body encloses the first RF power die and having a package topside surface opposite the lower flange surface. Topside input/output terminals of the PA package are accessible from the package topside surface and are electrically interconnected with the first RF power die through the TTI arrangement and the first set of interposer mount pads.

Abstract: Leadless power amplifier (PA) packages and methods for fabricating leadless PA packages having topside terminations are disclosed. In embodiments, the method includes providing electrically-conductive pillar supports and a base flange. At least a first radio frequency (RF) power die is attached to a die mount surface of the base flange and electrically interconnected with the pillar supports. Pillar contacts are further provided, with the pillar contacts electrically coupled to the pillar supports and projecting therefrom in a package height direction. The first RF power die is enclosed in a package body, which at least partially defines a package topside surface opposite a lower surface of the base flange. Topside input/out terminals are formed, which are accessible from the package topside surface and which are electrically interconnected with the first RF power die through the pillar contacts and the pillar supports.

Abstract: Embodiments of Doherty Power Amplifier (PA) and other PA packages are provided, as are systems including PA packages. In embodiments, the PA package includes a package body having a longitudinal axis, a first group of input-side leads projecting from a first side of the package body and having an intra-group lead spacing, and a first group of output-side leads projecting from a second side of the package body and also having the intra-group lead spacing. A first carrier input lead projects from the first package body side and is spaced from the first group of input-side leads by an input-side isolation gap, which has a width exceeding the intra-group lead spacing. Similarly, a first carrier output lead projects from the second package body side, is laterally aligned with the first carrier input lead, and is separated from the first group of output-side leads by an output-side isolation gap.
