Picco, G., Ourednik, P., & Feiginov, M. (2026). Advantages of High-Current-Density Resonant-Tunnelling Diodes at sub-THz Frequencies. In 2025 50th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz) (pp. 1–2). IEEE. https://doi.org/10.1109/IRMMW-THz61557.2025.11319818
We experimentally demonstrate significantly higher radiated power of resonant-tunnelling-diode (RTD) oscillators with high-current-density RTDs at relatively-low sub-THz frequencies compared to RTDs with lower current density. The results confirm our former theoretical analysis and predictions. The demonstration is done with symmetrical-slot-antenna RTD oscillators. However, it confirms a more general trait: RTD oscillators with high-current-density RTDs are not only advantageous at higher frequencies, but they exhibit superior performance also in the low sub-THz frequency range.
