This paper presents an innovative topology of an ultra-broadband BPSK modulator. This novel architecture consists of a specific distributed amplifier and absorptive switches, providing amplitude flatness and low phase imbalance over the 0.5 - 18 GHz frequency bandwidth. Experimental results validate the performance of such a modulator over more than a frequency decade.
