Abstract: An electrical circuit for providing an output signal based on a first input signal and a second input signal has: a mixer which is configured to receive and mix the first and second input signals in order to generate a mixer output signal and to switch on or off based on the first input signal, wherein a DC signal component of the mixer output signal depends on whether the mixer is switched on or off; and a downstream circuit which is configured to switch on or off based on the DC signal component of the mixer output signal and to provide the output signal based on the mixer output signal.

Abstract: A radio-frequency device comprises a semiconductor package, which comprises a radio-frequency chip and a radio-frequency antenna. The semiconductor package is designed to be mechanically and electrically connected to a circuit board via at least one connecting element of the semiconductor package, with one surface of the semiconductor package facing the circuit board. The radio-frequency device also comprises a waveguide structure oriented in a direction parallel to the surface of the semiconductor package, the radio-frequency antenna being designed for at least one of the following: to emit radiation into the waveguide structure in the direction parallel to the surface of the semiconductor package, or to receive signals via the waveguide structure in the direction parallel to the surface of the semiconductor package.
