A nine-MESFET two-dimensional power-combining array employing an extended resonance technique

Abstract

A spatial power combining circuit that forms a single resonant structure from many active devices is introduced. A large-signal analysis of this power combiner was performed. Based on these results, a two- and a nine-MESFET two-dimensional combiner driving two- and nine-patch antenna elements, respectively, were designed and fabricated. Measured results are presented. An effective radiated power of 6.06 W at 7.33 GHz was obtained from the nine-MESFET combiner.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
