Personal History :    
He joined the Electrical Communications Laboratories, Nippon Telegraph, and Telephone Corporation (now NTT), Japan in 1974.

 

Since then, he had carried out the research and development of microwave and millimeter-wave GaAs-FET circuits, Si-bipolar and GaAs-FET MIC, MIC and MMIC reliability in space, satellite on-board equipment such as a high power amplifier, a large scale GaAs-FET MMIC switch matrix,  and a Multi-Port-Amplifier (MPA), satellite payload evaluation systems and satellite system analysis.

 

He had also been involved in the design and development of payload systems for fixed and mobile communications services for Japanese commercial and experimental communications satellites, including CS-2, CS-3, ETS-4, ETS-6, and N-STAR satellites.

 

From 1986 to 1994, he was the chief of the research and development for satellite onboard equipment.

 

From 1995 to 1998, he was Director of the Research Planning Department and Chief of the three-dimensional (3D) MMIC Development Project at NTT Wireless Systems Laboratories.

 

From 2001 to 2017, he was a professor at the Department of Electrical and Electronic Engineering, College of Industrial Technology, Nihon University.

 

From April 2017 to March 2020, he was an adjunct professor at the Department of Electrical and Electronic Engineering, College of Engineering Technology, Nihon University.

​

Since April 2017, he has been an adjunct professor at the Graduate School of Electrical and Electronic Engineering, College of Engineering Technology, Nihon University.
