Resonant Tunneling Diodes for Sub-Terahertz and Terahertz Oscillators

Autor: Naomichi Kishimoto, Safumi Suzuki, Masahiro Asada

Publikováno v: Japanese Journal of Applied Physics. 47:4375-4384

Resonant tunneling diodes (RTDs) have the potential for use as compact and coherent terahertz (THz) sources operating at room temperature. In this paper, sub-THz and THz oscillators with RTDs integrated on planar circuits are described. Fundamental o

We report experimental and theoretical work on the dependence of oscillation frequency and output power on the offset of a feeding point and the aperture width of a slot antenna in sub-terahertz (THz) and THz resonant tunneling diode (RTD) oscillator

Sub-THz Resonant Tunneling Diode Oscillators With Offset-Fed Slot Antenna

Autor: Masahiro Asada, Naomichi Kishimoto, K. Hanashima, Safumi Suzuki

Publikováno v: 2007 IEEE 19th International Conference on Indium Phosphide & Related Materials.

We obtained sub-THz oscillation from resonant tunneling diode (RTD) oscillators with offset-fed slot antennas. The oscillation frequency without offset is about 350 GHz, whereas it increases to about 420-440 GHz with offset of 15 mum (60%) from the a

Frequency Increase of Resonant Tunneling Diode Oscillators in Sub-THz and THz Range Using Thick Spacer Layers

Autor: Naomichi Kishimoto, Atsushi Teranishi, Safumi Suzuki, Masahiro Asada

Publikováno v: Applied Physics Express. 1:042003

We obtained frequency increase of resonant tunneling diode (RTD) oscillators using thick spacer layers at the collector in sub-terahertz range. This is attributed to reduction of parasitic capacitance due to the increase of spacer layer thickness. Th
