Radio transmission device for the radio transmission of an interrogation signal based on a signal to be amplified

A radio transmission device for the radio transmission of an interrogation signal (SA1, SA2) based on a signal to be amplified (Sa1, Sa2), said interrogation signal (SA1, SA2) comprising a plurality of pulses, said radio transmission device comprising:

• a generator for generating a signal to be amplified (Sa1, Sa2),
• a power amplification chain for amplifying the power of the signal to be amplified (Sa1, Sa2) so as to form an interrogation signal (SA1, SA2),
• an interface module able to generate a trapezoidal signal (Strapez) applied as bias voltage in the power amplification chain so as to transmit each of the pulses of said interrogation signal (SA1, SA2),
• wherein said radio transmission device comprises a selection block for selecting a type of interrogation signal to be transmitted from among at least two different types (Type 1, Type 2) of signals, said generator for generating a signal to be amplified being configured so as to allow transmission of a signal to be amplified (Sa1, Sa2), so as to generate the interrogation signal (SA1, SA2) corresponding to the selected type (Type 1, Type 2) of interrogation signal.
