Abstract (en)
[origin: WO0115334A1] The invention relates to a device for coupling a high-frequency transmission signal (uHF) into a low voltage network (L1, N). An output amplifier (202) is provided. A differential mode voltage (uDiff) which is produced at a summing point (209) and represents an input voltage is supplied to the output amplifier between the transmission signal (uHF) and the feedback signal (urück). A network (206) is switched downstream in relation to the output amplifier (202) for adapting to the network impedance (ZL). Means (208) for detecting a voltage (umess) that is proportional to the network output current (iM) are arranged at the output of the network (206). The detected voltage (umess) is supplied to a controller module (207). The output signal of said controller module (207) is the feedback signal (urück).
