Abstract: An electrical inverter system including a first heat sink, a second heat sink and an electrical capacitor, stacked in that order. These three components can be fixed by a fixing means in such a way that they are not displaceable against each other and at least partially lie flat against each other. Furthermore, the system includes a semiconductor power module clamped between the heat sinks, and electrical contact elements electrically connecting the electrical capacitor and the semiconductor power module.

Abstract: A radio-frequency system includes an impedance tuning network having a plurality of selectable impedance states and a first port for coupling to a complex load impedance, a detector coupled to a second port of the impedance tuning network and configured to measure scalar values of reflection coefficients at the second port, and a controller configured to, for a first radio-frequency band, sequentially tune the impedance tuning network to at least three different impedance states in each of which the detector measures a scalar value of a corresponding reflection coefficient at the second port, and estimates a value of the complex load impedance based on the scalar values measured by the detector.

Abstract: An impedance matching network comprises a first and a second signal terminal and a reference potential terminal. The network further comprises a first shunt branch between the first signal terminal and the reference potential terminal, the first shunt branch comprising a variable inductive element and a first capacitive element. The impedance matching network also comprises a second shunt branch between the second signal terminal and the reference potential terminal and comprising a second capacitive element. A series branch between the first signal terminal and the second signal terminal comprises a third capacitive element. Optionally, the first, second, and/or third capacitive element may be implemented as a variable capacitive element. The variable capacitive element comprises a plurality of transistors, wherein a combination of off-capacitances Coff of the transistors provide an overall capacitance of the variable capacitive element as a function of at least two independent transistor control signals.
