This multifrequency device () is configured to be connected via at least two conductors () to an electricity supply grid (). This device comprises: at least one radiofrequency module () comprising at least one first and one second input/output port (), which ports are able to emit and/or receive radiofrequency signals at two different frequencies; and at least two matching circuits () that are configured to block the propagation of radiofrequency signals propagating over the conductors, each matching circuit comprising a plurality of terminals. One terminal () of each matching circuit is connected to the first conductor or to the second conductor. One terminal () of each matching circuit is connected to the first input/output port or to the second input/output port of the radiofrequency module. This device also comprises decoupling means (C, C) that are configured to stop the propagation of electrical supply signals between the conductors and between at least one conductor and an input/output port of the radiofrequency module.

Multifrequency device, controlling and/or monitoring device, associated multifrequency system and piece of home-automation equipment

And the point of connection () of the coupler () is disposed between the first and second ends () of the printed transmission line ().

Device for control by radiofrequency signals of a domestic electrical appliance, associated domestic electrical appliance and home automation installation comprising such an appliance

Radiofrequency device ('&#x2033;) controlling means for supplying at least one electrical load (&#x2032;) and comprising a radiofrequency unit () of radiofrequency signals transmitter and/or receiver type and connected by a first conductor () to the AC mains (), wherein the radiofrequency unit comprises a radiofrequency signal output and/or input () connected by an HF link () to a first terminal () of a tuning circuit (&#x2032;) of the radiofrequency device, this tuning circuit being:

Device of radioelectric signals transmitter and/or receiver type

A drive device with radiofrequency control includes a motor, a radiofrequency receiver for receiving radiofrequency signals and for controlling the motor. Electrical conductors provide power for both the motor and the radiofrequency circuit. The antenna is connected to the radiofrequency receiver and is non-galvanically electrically coupled one of the conductors at radiofrequencies. The control circuit receives radiofrequency signals directly through the antenna or via radiofrequency coupling from one of the power supply conductors. The device has increased ability to receive radiofrequency signals independent of its environment.
