Silicon micromachined waveguide components at 0.75 to 1.1 THz

Description: Silicon micromachined waveguide components operating in the WM-250 (WR-1) waveguide band (0.75 to 1.1 THz) are measured. Through lines are used to characterize the waveguide loss with and without an oxide etch to reduce the surface roughness. A sidewall roughness of 100nm is achieved, enabling a wav...

Silicon micromachined lens antenna for THz integrated heterodyne arrays

Description: In this paper, we present the design, fabrication, and measurements of a lens THz antenna that can be fabricated using conventional photolithography and deep reactive etching processes. The antenna is composed of an extended hemispherical silicon lens and a leaky wave waveguide feed. Both elements a...

Compact duplexing for a 680-GHz radar using a waveguide orthomode transducer

Description: A compact 680-GHz waveguide orthomode transducer (OMT) and circular horn combination has been designed, tested, and characterized in a radar transceiver's duplexer. The duplexing capability is implemented by a hybrid waveguide quasi optical solution, combining a linear polarization OMT and an extern...

Terahertz antennas with silicon micromachined front-end

Description: Increasingly, terahertz systems are being used for multi-pixel receivers for different applications from mapping the star-forming regions of galaxies to stand-off radar imaging. Since microstrip patch antennas are too lossy and corrugated horn antenna arrays are difficult to machine at terahertz fre...

Silicon microlens antenna for multi-pixel THz heterodyne detector arrays

Description: Silicon micromachined RF passive components such as washers, waveguide with 90 degree bends for 325-500 GHz band, and silicon-stacked blocks for W-band (75-110 GHz) GaAs power amplifiers have been designed, microfabricated, and characterized. Based on these results, we have successfully stacked seve...
