Abstract

A planar periodic MESFET based spatial power combiner was designed and fabricated for X-band operation. In this combiner four MESFET devices driving a linear microstrip antenna array are periodically connected to a microstrip transmission line. A large-signal analysis of this combiner and experimental results thereon are presented. An effective radiated power of 484 mW was achieved for this structure at an oscillation frequency of 10.02 GHz with a power combining efficiency of 87%
