1. An electro-optical mixer (4) having an electrical output, the electro-optical mixer comprising:
a photodiode for converting an incident optical signal,
a first terminal,
a second terminal,
wherein a first voltage supply can be connected to the first terminal, and a second voltage supply can be connected to the second terminal, or a first power supply can be connected to the first terminal, and a second power supply can be connected to the second terminal,
a terminal for a small-signal ground potential for the first voltage supply and the second voltage supply,
a first partial matching network which is arranged on an anode side of the photodiode, wherein a portion of the first partial matching network is switchably connectable to the second terminal for the second voltage supply, and wherein another portion of the first partial matching network is switchably connectable to the terminal for the small-signal ground potential,
a second partial matching network which is arranged on a cathode side of the photodiode, wherein a portion of the second partial matching network (Z1) is switchably connectable to the first terminal for the first voltage supply, and wherein another portion of the second partial matching network is switchably connectable to the terminal for the small-signal ground potential,
wherein elements of the first partial matching network and the second partial matching network feature an inductive and/or a resistive character and/or a capacitive character,
a first capacitive element which is arranged on the cathode side of the photodiode,
a second capacitive element which is arranged on the anode side of the photodiode,
wherein a first decoupling element and a second decoupling element feature an inductive and/or a resistive character and/or a capacitive character,
wherein an electrical output signal is provided during operation between sides of the first decoupling element and the second decoupling element facing away from the photodiode.
