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: A direct current (DC)-DC converter that includes a first switching converter and a multi-stage filter is disclosed. The multi-stage filter includes at least a first inductance (L) capacitance (C) filter and a second LC filter coupled in series between the first switching converter and a DC-DC converter output. The first LC filter has a first LC time constant and the second LC filter has a second LC time constant, which is less than the first LC time constant. The first LC filter includes a first capacitive element having a first self-resonant frequency, which is about equal to a first notch frequency of the multi-stage filter.
