Abstract :
We report a room temperature operation of resonant tunneling diode (RTD) oscillators with high output power of around 400 μW at frequencies of 530-590 GHz, using large-area RTDs and an optimized structure of offset-fed slot antennas. The highest output power obtained in this study was 420 μW at 548 GHz for a single RTD with a peak current density of 24 mA/μm2; the RTD was placed 58 μm apart from the center of a 130-μm-long slot antenna.
