Abstract

The invention discloses a high-isolation small-sized radial power distributor/synthesizer. The high-isolation small-sized radial power distributor/synthesizer comprises a radial power distributor/synthesizer of an inserted resistor diaphragm and a rectangular waveguide-circular waveguide mode conversion structure, wherein the radial power distributor/synthesizer of the inserted resistor diaphragm comprises an input circular waveguide port, an impedance transformation structure and more than one output rectangular waveguide; the three structures are connected in sequence; the rectangular waveguide-circular waveguide mode conversion structure comprises an input rectangular waveguide, a one-into-four power distribution network, a waveguide expansion transition structure and an output circular waveguide which are connected sequentially. The power distributor/synthesizer can realize power multiplexing, wide band, low loss, small size, easy assembly and power distribution/synchronization of port isolation.

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...
