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 com biner and experimental results thereon are presented. An effective rad iated power of 484 mW was achieved for this structure at an oscillatio n frequency of 10.02 GHz with a power combining efficiency of 87%.
