Abstract
A radio transmission device for the radio transmission of an interrogation signal based on a signal to be amplified is provided. This method comprises a generator for generating a signal to be amplified, and a selection block for selecting a type of interrogation signal to be transmitted from among at least two different types of signals. The generator for generating a signal to be amplified is configured so as to allow transmission of the signal to be amplified so as to generate the interrogation signal corresponding to the selected type of interrogation signal.

A radio transmission device for the radio transmission of an interrogation signal based on a signal to be amplified, said interrogation signal comprising a plurality of pulses, said radio transmission device comprising:
- a generator for generating the signal to be amplified, said generator comprising a pre-distortion device for pre-distorting the pulses of the signal to be amplified on a carrier frequency;
- a single power amplification chain for amplifying the power of the signal to be amplified so as to form the interrogation signal;
- an interface module able to generate a trapezoidal signal applied as bias voltage in the power amplification chain so as to transmit each of the plurality of pulses of the interrogation signal;
- wherein said radio transmission device comprises a selection block for selecting an interrogation signal type from among at least two different interrogation signal types, said generator for generating the signal to be amplified being configured so as to allow transmission of the signal to be amplified, so as to generate the interrogation signal corresponding to the selected interrogation signal type.
A method for the radio transmission of an interrogation signal based on a signal to be amplified in a radio transmission device comprising a single amplification chain, the interrogation signal comprising a plurality of pulses, said method comprising:
- a step of generating the signal to be amplified, and to apply a pre-distortion to pulses of the signal to be amplified;
- a step of amplifying the power of the signal to be amplified so as to form the interrogation signal;
- a step of generating a trapezoidal signal applied as bias voltage during the power amplification step so as to transmit each of the pulses of the interrogation signal;
- wherein said radio transmission method comprises:
- a step of selecting an interrogation signal type from among at least two different interrogation signal types, the step of amplifying the power of the signal to be amplified being configured so as to allow transmission of the signal to be amplified so as to generate the interrogation signal corresponding to the selected interrogation signal type.
