AbstractAfter a brief glimpse of the composition of a modern airborne transmitter, a reminder is given of how the choice of a servoed carrier scheme after frequency division on a quartz crystal reference, favoring transmissions at high data speed, has opened up the way to a whole generation of frequency synthesis transmitters covering the 2.1 - 2.7 GHz band in sub-bands of 150 MHz with a pitch of 0.5 MHz. The advantages of frequency synthesis from the quadruple aspect of maintenance, availability “on the shelf”, flexible use in a congested frequency plan and discretion, are then commented on. Finally, in a last section - more theoretical than the previous ones - the technical difficulties which arise from the “spirit” of frequency synthesis are referred to.
