Abstract: A radio frequency (RF) switch semiconductor die and an RF supporting structure are disclosed. The RF switch semiconductor die is attached to the RF supporting structure. The RF switch semiconductor die has a first edge and a second edge, which may be opposite from the first edge. The RF supporting structure has a group of alpha supporting structure connection nodes, which is adjacent to the first edge; a group of beta supporting structure connection nodes, which is adjacent to the second edge; and an alpha AC grounding supporting structure connection node, which is adjacent to the second edge. When the group of alpha supporting structure connection nodes and the alpha AC grounding supporting structure connection node are active, the group of beta supporting structure connection nodes are inactive.

Abstract: Circuitry, which includes a direct current (DC)-DC converter having a first switching power supply is disclosed. The first switching power supply includes a first switching converter, an energy storage element, a first inductive element, which is coupled between the first switching converter and the energy storage element, and a first snubber circuit, which is coupled across the first inductive element. The first switching power supply receives and converts a DC power supply signal to provide a first switching power supply output signal based on a setpoint.
