Description

technical field [0001] The invention relates to the technical field of spatial power combining in microwave and millimeter wave frequency bands, in particular to a miniaturized radial power distribution / combiner with high isolation. Background technique [0002] Today, millimeter wave and submillimeter wave communication technologies are moving from research to practical application. With the increase of operating frequency, the power capacity of semiconductor solid-state devices decreases, and the output power of a single device is difficult to meet the needs of communication electronic systems. People generally use the method of power combining network to realize high-power solid-state power devices. The focus of research on power combining technology is to explore which combining network topology can realize the power combining of large numbers of broadband with maximum efficiency. [0003] Among various power combining network topologies, the radial power splitter / combi...
