Book excerpt: Millimeter-wave imaging diagnostic instruments developed by Davis Millimeter Research Center (DMRC) have made important contributions to fusion science and have been adopted at major fusion facilities worldwide: Electron cyclotron emission (ECE) imaging is a passive radiometric technique that measures electron temperature fluctuations; and microwave imaging reflectometry (MIR) is an active radar imaging technique that measures electron density fluctuations. These instruments have been comprised with the combination of discrete waveguide components and board-level surface mount components employing quasi-optical coupling in the front-end system. Aim to implement ultra-wideband observation for visualizing the 2-D images of fusion plasma in the old days, the conventional passive down-converting mixer mounted on the printed board antenna with mini lens offers the most reliable method therefore becomes the first generation of above techniques. Such technology has been widely applied and has provided crucial contributions on sawtooth, Alfven eigenmodes, and ELMs. Until recent, existing systems have been installed in several major magnetic confinement devices around the world, such as DIII-D, KSTAR, ASDEX-U, EAST, HL-2A, TEXTOR and J-TEXT. Nowadays, advances in device fabrication and the scaling of feature size have recently extended the maximum operating frequency of integrated circuits considerably in excess of a hundred gigahertz. The groundbreaking improvement on the electronic device, a multi-function instrumentation can be implemented by integrating the entire front-end system on a single chip, which is known as system-on-chip (SoC) technique. In this dissertation, the author will introduce the system from the previous hardware limitations to the system-on-chip advancement for fusion science applications and will deliver the details of the waveguide horn antenna array with single MMIC receiver module. Fusion plasma diagnostics require operation at specific frequencies with >20 GHz bandwidth limiting the usefulness of commercial products. The in-house designed receiver chip offer >30 dB signal amplification over 20 GHz bandwidth with
