Center Overview

The mission of the Center for High-Frequency Electronics and Circuits for Communication Systems (CHECCS) is to develop innovative and multidisciplinary solutions to address technical challenges in the increasingly complex area of advanced electronics and circuits for communications systems. CHECCS develops different levels of integrated components, subsystems, and multiscale systems for current and future high-frequency communication systems. CHECCS strives to accelerate technology transfer of research into commercially viable products, stimulate spinoffs and startup companies, and enable the growth of local industries.

High-frequency communication systems have penetrated almost all aspects of our daily life, with applications including autonomous cars, personalized medicine, monitored health care, agricultural sensing, and merchandise inventory systems. The scope of CHECCS’ work includes materials, electronics, devices, circuits, radiation, and their applications.

CHECCS conducts research in radio frequency (RF) communication devices, circuits, and systems. Its work in advanced telecommunications includes 5G and future systems, sensors, drones, high-resolution imaging, and up to terahertz (THz) frequency technology. The RF/microwave/mm-wave industry encompasses a wide range of companies and government facilities engaged in the synthesis, processing, and applications of electronic devices and circuits. Applications include defense systems, personalized medicine and monitored health care, agricultural sensing, and merchandise inventory.

CHECCS aims to satisfy the national need for qualified U.S. engineers and scientists who have deep knowledge of various technically challenging areas supporting high-frequency communications. The center educates students in these advanced topics and equips them with skills that are in high demand to prepare them for careers serving the commercial or defense sectors, national research labs, or academia.
