Abstract
A diode network having at least one diode which during operation is located in the path of an HF signal, a predetermined diode voltage being applied to the diode to adjust its operating point, is characterised in that a control device is provided to maintain the diode voltage constant. With the invention it is advantageous that, due to the measurement of the DC voltage acting on the diode itself and influencing the operating point, it is not necessary to provide a low-resistance coupling between a voltage source and the diode, with respect to direct current.
