Abstract
We demonstrate the operation of resonant tunneling diode (RTD) oscillators with high output power (100–200 µW) at frequencies of 430–460 GHz using an offset-fed slot antenna in which the RTD is placed at a certain distance from the center of the slot. The highest output power obtained in this study was 200 µW at 443 GHz for a single RTD with a peak current density of 18 mA/µm2; the RTD was placed 45 µm from the center of a 100-µm-long antenna. Higher output is expected by optimizing the position and mesa area of the RTD and the antenna length.
