Problems solved by technology

However, this tapered ridge configuration reduces the power capability of the power splitter / combiner
In addition, according to the requirements of impedance matching, the radial curve gradient ridge array must be connected to the standard coaxial inner conductor through a certain length of rectangular coaxial inner conductor, which will make the volume of the entire power distribution / combiner larger and increase the design the complexity
At the same time, this gradual structure requires high machining accuracy, making it difficult to realize the process.

Description

technical field [0001] The invention belongs to the field of microwave / millimeter wave passive devices, and in particular relates to a broadband radial waveguide power distribution / combiner with a cycloid-like transition structure. Background technique [0002] As one of the core modules in a millimeter-wave communication system, the solid-state power amplifier's power output level and operating bandwidth determine the overall communication system performance. The output power of single-chip microwave solid-state chips is limited, and it is difficult to achieve high-power output requirements. In order to meet the high-power output requirements of application systems, the usual technical approach is to use power synthesis technology to synthesize the output power of multiple solid-state chips. [0003] The technical solutions of microwave and millimeter-wave power combining usually include: planar power distribution / combination technology, space power combining technology and...
