This session brings together four papers showcasing sub-THz and THz signal modulation techniques for next-generation communication systems. The first paper introduces attenuator-based vector modulation strategies for phased arrays operating from 200 to 480GHz. The second paper demonstrates a novel photoconductive solid-state plasma evanescent-mode waveguide for sub-THz phase shifting. The third paper presents a compact 8.2mW complementary current-reusing D-band frequency quadrupler implemented in 22nm FDSOI CMOS. Finally, the fourth paper compares wideband low-power H-band frequency doublers, with and without driving stages, also in 22nm FDSOI CMOS, highlighting performance trade-offs. These advances significantly elevate future sub-THz communications.
