Abstract:
A generator device for generating radio frequency electric signals, delivering at least two separate signals having different frequencies in the form of signals delivered by different primary sources and amplified with a predetermined gain, characterized in that it comprises, in addition to said primary sources (2), on the one hand, a combining circuit (3), combining, without intermodulation, the signal or signals delivered by the primary sources (2), on the other hand, by a single channel wideband power amplifier (4) having a pass band adapted to the different frequencies (F) of the signals present in the combined signal from the combining circuit (3) and, finally, by a multi-channel selection and routing unit (5) with parallel structure, of which each channel delivers at the output an amplified signal (S) at a frequency (F) characteristic of the one of the primary sources (2) and comprises a filter circuit (6) adjusted to be passing for one of the different characteristic frequencies (F) of the different primary sources (2), an impedance adaptation circuit (7) and a rejection circuit (8) for frequencies other than the passing frequency of the filter circuit (6) of the selected channel.
