This session presents advanced frequency multiplication techniques for signal generation from 100 to 310GHz in CMOS and SiGe technologies. The papers demonstrate phase-aligned harmonic recombination, coupled-line-based output matching, amplifier–multiplier chains, and coherent power combining to enhance efficiency, output power, bandwidth, and harmonic suppression. Reported results include up to 16dBm output power, +26.5dBm EIRP, and >70dBc harmonic rejection. Together, these works illustrate scalable circuit strategies for high-purity, high-power D-band and sub-THz transmitters suitable for emerging communication and sensing applications.
