Resonant Tunneling Diode Oscillator Source for Terahertz Applications

Resonant tunneling diode (RTD) is the fastest solid-state electronic device with the highest reported frequency at 1.92 THz [1]. RTD-based THz sources have many promising applications such as ultrafast wireless communications, THz imaging, etc. To date, the main limitation of RTD technology is the low output power. Here we report the series of nearly/over one half mW output power RTD oscillator. The frequencies range from 125 GHz to 308 GHz and the preliminary wireless communication measurement result demonstrates data rate up to 7Gbps
