Abstract
A radar level gauge system comprising power management circuitry for regulating operating power to be used by a microwave unit and a processing circuitry of the radar level gauge system. The power management circuitry comprises a DC-DC converter having an input terminal connected to the interface, an output terminal connected to the microwave unit and the processing circuitry, and a reference terminal connected to an electrical reference point, wherein a first voltage level at the input terminal and a second voltage level at the output terminal relates to a reference voltage level at the electrical reference point. The power management circuitry further comprises an energy storage capacitor connected between the input and output terminals of the DC-DC converter. According to this design, the capacitance of the power management circuitry gets reduced due to that the capacitance is originating from a series capacitance.
