Sub-terahertz wireless communication technology at G-band

This work presents a sub-terahertz wireless communication system design that uses a G-band 0.17THz electromagnetic waves. The key components of subharmonic mixer (SHM) with planar Schottky diode and high performance 170GHz MEMS rectangular waveguide filters are demonstrated. The simulated optimum conversion loss of the 170 GHz SHM is 8.35 dB, and the MEMS rectangular waveguide filters have been fabricated and the measured lowest insertion losses are lower than 1.5 dB.
