| 摘要 |
A device for control by radiofrequency signals (22) of a domestic electrical appliance powered by an electrical power supply network comprising a first electrical conductor (26) and a second electrical conductor (27) for powering the device (22), a coupler (31), a radiofrequency unit (23) comprising an output and/or an input for the radiofrequency signals (28) which is linked electrically to a point of connection (33) of the coupler (31). The coupler (31) is formed by a printed transmission line (32) on a printed circuit board (29), a first end (34) of the line (32) being linked electrically to the first electrical conductor (26) of the device (22), and a second end (35) of the line (32) being linked electrically to a first reference voltage. And the point of connection (33) of the coupler (31) is disposed between the first and second ends (34, 35) of the printed transmission line (32). |
