An electronic circuit comprises a high-pass and a low-pass. The low-pass comprises at least one low-pass series element and a low-pass transverse element. The high-pass comprises at least one high-pass series element and a high-pass transverse element. The low-pass series element and the high-pass transverse element are realised in this context by a common component, and/or the high-pass series element and the low-pass transverse element are realised in this context by a common component.

Switchable frequency diplexer circuit

An electronic switch contains an input terminal, and output terminal and at least one first switch element, which provides a voltage-dependent characteristic. In this context, the first switch element connects the input terminal to the output terminal in a selective manner. The electronic switch further comprises a compensation element, which provides a voltage-dependent characteristic. In this context, the compensation element is arranged in such a manner that it at least partially compensates the frequency-dependent characteristic of the switch element.

Electronic switch with compensation of non-linear distortions

A signal generator including a DDS-signal source that is configured to operate according to the principle of direct digital synthesis (DDS), and a PLL signal synthesizer that is configured to operate according to the principle of phase locked loop (PLL) using an output signal from the DDS-signal source as a reference signal. The DDS-signal source can be connected via a direct connection, without further frequency division or mixing, directly to an output of the signal generator or directly to a level-adjustment device of the signal generator in order to generate a portion of an overall frequency range of an output signal of the signal generator.
