​

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 engaged in the design and development of payload systems of Japanese commercial and experimental communications satellites, such as CS-2, CS-3, ETS-4, ETS-6, and N-STAR for fixed and mobile communications services.

 

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

 

From 1995 to 1998, he was an executive manager of the Research Planning Department and also a project leader of three-dimensional MMIC development 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 a specially-appointed professor at Nihon University.

​

Since April 2020, he has been a part-time lecturer at Nihon University (graduate course).
