Abstract:
1. An RF power amplifier comprising: (a) a controller, a driver amplifier, a splitter, a final stage, and a combiner coupled together to function as the RF power amplifier; (b) a motherboard printed circuit board (PCB), the motherboard PCB including electrical components for at least the splitter; (c) a heat sink defining a base of the RF power amplifier, wherein the heat sink includes at least two grooves formed therein, wherein the electrical components of the splitter and electrical components of the controller fit within one or more of the grooves; (d) wherein the heat sink serves as an EMI shield for RF and spurious emissions, and wherein the heat sink dissipates heat from the electrical components of the splitter and the electrical components of the controller; and (e) a power rail to distribute a DC voltage to the final stage, wherein a power rail groove of the heat sink shields the power rail.
