A high-frequency switching assembly having a first switching state and a second switching state includes a transmitter and a switch assembly. The transmitter includes a primary side and a secondary side having a first secondary side terminal and a second secondary side terminal and is configured to transmit an HF input signal applied to its primary side to its secondary side by means of inductive coupling. The switch assembly is configured to apply, in one state, a first reference potential to the first secondary side terminal. Further, the switch assembly is implemented to apply, in another state, a second reference potential to the second secondary side terminal. |

1. A high-frequency switching assembly comprising a first switching state and a second switching state, comprising:
a transmitter comprising a primary side and a secondary side, the secondary side comprising a first secondary side terminal and a second secondary side terminal, wherein the transmitter is configured to transmit a HF input signal applied to a primary side to a secondary side by an inductive coupling; and a switch assembly configured to apply, in the first switching state, a first reference potential to the first secondary side terminal, such that, in the first switching state, a first transmitter output signal is tapped at the second secondary side terminal, which is based on the HF input signal applied to the primary side of the transmitter, and to apply, in the second switching state, a second reference potential to the second secondary side terminal, such that, in the second switching state, a second transmitter output signal is tapped at the first secondary side terminal, which is based on the HF input signal applied to the primary side of the transmitter; wherein the switch assembly comprises a first switch configured to apply, in the first switching state, the first reference potential to the first secondary side terminal, and a second switch configured to apply, in the second switching state, the second reference potential to the second secondary side terminal; wherein control terminals of the first switch and the second switch are coupled to a reference potential change-over switch, wherein the reference potential change-over switch is configured to provide, in the first switching state, a third reference potential or the second reference potential at the control terminals of the first switch and the second switch and to provide, in the second switching state, the first reference potential at the control terminals of the first switch and the second switch such that, in the first switching state, the first switch is in a conductive state to apply the first reference potential to the first secondary side terminal, and such that, in the second switching state, the second switch is in the conductive state to apply the second reference potential to the second secondary side terminal; wherein the reference potential change-over switch comprises an inverter configured to provide either the first reference potential or the second reference potential at the control inputs of the first switch and the second switch in dependence on a control signal applied to an input of the reference potential change-over switch. |
