Abstract (en)
[origin: EP1406349A2] The device has a passive part with output connections connected to amplifier stage input connections and reduced internal impedance if a defined reception level is exceeded. The amplifier input stage amplifying element's high impedance control port has a HF connection to the passive part. An electronic element reduces the reception level in a transfer network whose linearising input admittance is lower when the HF input signal is attenuated. The device consists of a passive part (1) whose output connections are connected to the input connections of an amplifier stage (21) and its internal impedance is reduced when a defined reception level is exceeded. The amplifier-input stage contains a 3-pole amplifying element (2) whose high impedance control port (15) has a high frequency connection to the first connection of the passive part. The amplifier has an electronic element (32) for reducing the reception level in a transfer network (31), whose linearising input admittance (7') is lower when the high frequency input signal is attenuated.
