abstract: In this report, the reception of a signal avoiding undesired amplitude modulations of the received power is yielded by optimising the sequence of on–off pulses controlling the RF switches. More specifically, the ‘switch-on instants’ (i.e., the time-instants when the switches commute from the open to the short circuit state) are suitably optimised to keep constant as much as possible the maximum directivity throughout the modulation period while generating an average pattern with prescribed sidelobes and mainbeam width at the working frequency.
