Double-resonant-tunneling-diode bridge-less patch-antenna oscillators operating up to 1.09 THz

Resonant tunneling diode oscillators for optical communications

The ability to use resonant tunneling diodes (RTDs) as both transmitters and receivers is an emerging topic, especially with regards to wireless communications. Successful data transmission has been achieved using electronic RTDs with carrier frequencies exceeding 0.3 THz. Specific optical-based RTDs, which act as photodetectors, have been developed by adjusting the device structure to include ...

Modeling and Analysis of Bow-Tie Antenna Integrated Resonant-Tunneling-Diode Relaxation Oscillators for Wireless Radio Applications

We propose a self-complementary bow-tie antenna-integrated resonant-tunneling-diode relaxation oscillator and investigate its oscillation/radiation characteristics. In the investigation, we establish a physics-based equivalent circuit model of the oscillator for taking the all physical phenomena related to the diode and the antenna into consideration simultaneously. In this paper, we report the...

Fabrication of Sub-THz Oscillators Using Resonant Tunneling Diodes Integrated with Slot Antennas

We fabricated sub-THz oscillators using resonant tunneling diodes integrated with slot antennas. Oscillations at 90GHz and 136GHz were obtained for the slot antennas with the lengths of 1mm and 800μm. Theoretical calculation shows that the maximum oscillation frequency up to ~1.2THz is expected in this structure with short antenna.
