Problems solved by technology
The power divider / combiner of the planar circuit has the advantages of small size and low cost, but the loss is relatively large; the power combiner based on the waveguide is characterized by extremely small loss, but the volume is often large
In addition, the bandwidth of ordinary waveguide E-plane or H-plane splitters is often limited, usually only 10% to 20% of the center frequency, and the application range is limited.

Description
technical field [0001] The invention relates to the technical fields of electromagnetic field, mechanical processing and micro-encapsulation, in particular to a low-loss waveguide structure suitable for waveguide power synthesis and distribution. Background technique [0002] In the field of microwave technology, microwave power amplifier is an indispensable component, and the most important indicators of microwave power amplifier are output power, efficiency and gain. In recent years, solid-state microwave power devices have developed rapidly, gradually replacing the bulky traveling wave tube amplifiers in the past. Semiconductor solid-state microwave devices have the characteristics of small size, light weight, and high stability. However, the biggest disadvantage of solid-state devices is that the output power is relatively low. In order to Obtaining high-power microwaves often requires the use of power synthesis. [0003] There are many ways of power combining, mainly W...
