Profile

In 1976, Prof. Honjo joined NEC Corporation, Kawasaki, Japan. He has been involved in the research and development of GaAs FET high-power amplifiers, ultra-broadband amplifiers, oscillators, mixers and MMIC technology. He has also been involved in device and circuit technology developments for microwave and millimeter-wave HBT’s, 10-40Gbps fiber optic communication systems, microwave Si power MOSFET. From 1987-1993, he was Manager, Research of Micro-electronics Research Labs, NEC, and from 1993-1999, he was Senior Manager of Opto-electronics Research Labs, NEC.

He moved to the University of Electro-Communications in 2001 as a professor at Information and Communications Engineering Department. At the university, he has established ultra-high efficiency class-F and class-R GaN HEMT amplifier design method, where more than 4th order higher harmonic frequencies can be taken into account under the existence of parasitic reactive elements. Also he has developed ultra-broadband active and passive components for UWB applications such as planar self-complementary antennas, HBT MMIC amplifiers with active balun, broad-side coupled four-line band pass filters with designed frequency notch. He has also been developing a co-simulation technique of electromagnetism and semiconductor device physics for microwave/millimeter wave devices and high-efficiency microwave rectifiers as a time reversed dual of high-efficiency power amplifiers.

Prof. Honjo is a Fellow of the IEEE and a Fellow of the IEICE. He received the 1983 IEEE MTT-S Microwave Prize for a proposal of novel circuit topology for ultra-broadband amplifiers, and he also received the 1988 IEEE MTT-S Microwave Prize again for a proposal of novel circuit synthesis method for frequency division and its PLL applications. He received the 1999 IEICE Electronics Award for development of microwave and digital HBTs, and 1980 IEICE Young Engineer Award for development of high power GaAsFET internal matching circuits . From 1988-1992, and from 1999-2003, he served as a TPC member for MTT-S microwave and millimeter-wave monolithic circuit symposium and IMS, respectively. From 1998 to 2003, he had served as an elected AdCom member of IEEE MTT-S. He served as a Chairman of MTT-S Transnational Committee for 5 years.

Prof. Honjo has 121 peer-reviewed journal publications, 128 international conference proceedings papers, 394 domestic conference presentations, has written 22 books/book chapters. He holds 99 Japanese patents and 19 US patents, 3 European patents, and 3 Chinese patents. Prof. Honjo has graduated 8 PhD students and 37 Master course students.
