SiGe Transmitter and Receiver Circuits for Emerging Terahertz Applications

Abstract

This paper presents recent developments on transmitter and receiver circuit in advanced SiGe technologies for emerging applications in the sub-millimeter wave region of the electromagnetic spectrum. This includes high-power harmonic oscillators, multiplier chains, and heterodyne I/Q transmitters for terahertz signal generation, as well as direct detectors, heterodyne receivers and Radar transceivers for wide-band signal detection. The circuits are attached to a secondary silicon lens and packaged on low-cost FR4 printed circuit boards.
