<p>For switching of electromagnetic signals of a field of decametre up to centimetre waves, there is designed an electronic relay comprising at least two branches with a common node, each branch (X1, X2) being furnished with a dipole (A) having at least one diode (7) and being connected in series through a series capacitor (2) with a lowpass frequency LC-filter, the series capacitor (2) having a capacity value at least five times higher than a transition capacity of the diode (7). The dipole (A) is further connected to a source of a first control voltage (U¿1?), while a source of a second control voltage (U2) is connected between an input and an earth terminal (5) of the low-frequency LC-filter. The applied network capacity element is connected to the earth terminal (5) and comprise a diode (7) having a threshold frequency lower than the highest switched frequency. Preferably the earth terminal (5) of the low-frequency LC-filter is connected to the ground via a grounding capacitor (6) having a capacity the value of which is at least five times higher than a transition capacity of the diode (7) of the low-frequency LC-filter.</p> |
