Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional cavity resonator devices are used, then they can handle high power applications, but they have limitations in achieving high coupling strength for RF signals
Solution Approach 1:
The coupling element is divided into multiple coupling arms (first coupling arm and second coupling arm) that connect the base section to the top section. This segmentation allows each arm to contribute to the overall coupling strength, enabling high coupling capability while maintaining high power handling through the distributed structure of multiple arms rather than a single concentrated element
Solution Approach 2:
The coupling element introduces a rotational degree of freedom around the longitudinal axis, adding a dimensional aspect to the coupling mechanism. By rotating the coupling element, the coupling strength can be adjusted without affecting the power handling capability, thus resolving the contradiction between achieving high coupling strength and maintaining power handling capability
