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: Disclosed herein is an edge-type lighting device which is configured such that when a light guide plate thermally expands, a light source is prevented from being pressed. In the lighting device according to the present invention, a light guide plate (2) is slidably supported so that the light guide plate (2) can expand in the planar direction, and a light source (3) disposed on an edge of the light guide plate (2) is movably supported in the same direction. A light-guide-plate stopper (4b) is disposed at a position facing an edge (2A) of the light guide plate (2) to prevent the light guide plate (2) from expanding excessively. Thus, the light source (3) can be prevented from being pressed toward a frame member (4).

Abstract: The present invention relates to an edge-type lighting device using an LED light source which has high light-emitting efficiency regardless of thermal expansion of a light guide plate. An LED light source (3) is disposed on an edge of a light guide plate (2) so as to be movable in the normal line direction (±n) of the edge (2c) of the light guide plate. A slide member (7) is slidably disposed on the rear surface of the LED light source. A spring (8) is disposed in a frame member (4) on the rear surface of the slide member. Thus, the LED light source can always be pressed toward the edge of the light guide plate regardless of the thermal expansion of the light guide plate. Because the spring has a simple structure, the lighting device can be compact compared to the case where a coil spring is used.
