Dr. K Elgaid FIET, SIEEE, is presently leading a high frequency devices and integrated circuits research team using GaN technology. He has >140 publications, presented 5 invited talks in international conferences/workshops in the past 2 years and co-authored a book chapter in “RFIC and MMIC design and technology”; widely regarded as a reference text, translated into Chinese in 2007. He has >20 years’ experience in MMIC technology development operating up to 325GHz, i.e. world leading mHEMT performance (fT/fmax = 440/400 GHz), InP HEMT performance (fT 550GHz), highest reported 300nm T-gate RF GaN on LR Si HEMT (fT/fmax = 55/121 GHz), demonstrated UK only 200GHz MMIC LNA, Ka-Band diode based MMIC mixers/LNA and state of the art MMIC compatible integrated THz antennas technology. He has collaborated with world leading national/international industrial partners (e.g. QinetiQ, BAE Systems, DTC and Keysight).

GaN technology, with its exceptional power output, power added efficiency and low noise performance has the potential to become the mm-wave integrated circuit technology of choice for many applications above 75GHz; providing a step change in performance in 5G telecommunications, sensing (e.g. automotive, security, satellite and medical), EW and radar applications, as well as Terahertz Sources (GaN Schottky diode based).


Dr. Khaled Elgaid FIET, SMIEE. He obtained B.Sc., Evansville USA, M.Sc., Cincinnati USA, and Ph.D., Glasgow UK.

My research interests span the design and realization of compound semiconductor microwave and millimetre-wave integrated circuits using state of the art in-house nanotechnology facilities. These activities utilise different compound semiconductor high-speed electronic devices; including devices fabricated using GaN and GaAs. The group enhances its research activities with further integration including on chip antennas at sub millimeter-wave and terahertz frequencies. My research activities are funded by several government and industrial grants and deliver research in high-speed wireless communications, radar, sensors and systems applications. I have published over 130 papers in my research field area and invited speaker at several international conferences.
