Abstract (in Japanese) (See Japanese page) 
(in English) We have developed a solid-state power amplifier (SSPA) for X-band marine radar systems employing new gallium nitride high electron mobility transistors (GaN HEMTs) of over 120W. The developed SSPA achieved the peak output power exceeding 400W, in combination of four GaN HEMTs, under pulse operation at 9.4GHz. The SSPA is small with the dimensions of 187×140×48 mm3, which enables reduction of the size of marine radar units. This result is part of R&D for improving the frequency utilization efficiency, which is a contract research from the ministry of internal affairs and communications.
