DEVICE REPRESENTING ELECTRIC RADIO SIGNAL TRANSMITTER AND/OR RECEIVER Russian patent published in 2013 - IPC H01Q1/00 

FIELD: electrical engineering.

SUBSTANCE: radiofrequency device controlling the means for feeding of at least one electric load and containing a radiofrequency unit representing a radiofrequency signal transmitter and/or receiver and connected to the feeding AC mains via the first wire. The radiofrequency unit contains a radiofrequency output and/or input, connected to the first terminal of the circuit via a HF connection; the radiofrequency device settings; the setting circuit is connected, via the second terminal, to the second wire and, via the third terminal,-to the electric ground (GND) of the radiofrequency unit and is equipped with a means for locking conductivity of radiofrequency signals via the first wire between the second terminal and the third terminal and alternating current (I-ACT) passing between the second terminal and the third terminal, flowing within the first wire and feeding the said electric load.

EFFECT: ensuring protection against parasitic overvoltage transmitted by the feeding mains.
