1. A circuit for a fill-level measuring device for fast switching-on of a high-frequency (“
- HF”
) element on a ground port, comprising;
a switching unit with a first ground port;
a high-frequency element with a second ground port that is designed as an HF ground port;
a coupling element; and
an insulation between the first and second ground ports;
wherein the switching unit is connected between the first ground port and the high-frequency element; and
wherein the second ground port is coupled, using an HF technology, by way of the coupling element, to the first ground port.

Abstract
A circuit for a fill-level measuring device is for the fast switching-on of a high-frequency element on a ground port is disclosed. The circuit comprises a switching unit with a circuit mass; a high-frequency element with a high-frequency mass; and a coupling element that couples the two masses together and at the same time insulates them from each other in a direct-current manner. In this way the switching unit can be arranged on the GND port of the HF-element, without influencing the HF characteristics of said HF element.
