Spliced Suspended Strip Line for Long RF Path Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspended strip lines with excessively long extension paths suffer from electrical function degradation, increased processing difficulty, and higher transportation and installation costs, limiting their application scenarios due to large length-width ratios and inconsistent line widths.
Innovation Solution
A splicing-type suspended strip line structure is introduced, where the strip line is disconnected into segments with a connector in between, allowing for easier fabrication and assembly, reducing signal loss, and facilitating transportation and mounting by maintaining consistent line widths and impedance matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the suspended strip line is extended to achieve functional requirements, then the signal transmission path is lengthened, but the electrical function degrades and processing difficulty increases
Solution Approach 1:
The suspended strip line is divided into multiple segments that can be separately processed and then spliced together. Each segment maintains manageable dimensions for fabrication while the complete assembled structure achieves the required functional length, preventing electrical function degradation that would occur with a single excessively long strip line.
2Length of moving object
If the suspended strip line is extended to achieve functional requirements, then the signal transmission path is lengthened, but processing difficulty and transportation costs increase
Solution Approach 1:
The strip line is segmented into multiple manageable sections that can be fabricated separately using standard processing techniques, avoiding the need to process a single excessively long component. This segmentation reduces processing difficulty while achieving the required total length through assembly of multiple segments.
Solution Approach 2:
Instead of extending the strip line in a single continuous dimension, the solution uses multiple segments arranged in space that are spliced together. This dimensional approach allows the functional length to be achieved through spatial configuration rather than single-dimension extension, reducing processing complexity.
3Length of moving object
If the suspended strip line is extended to achieve functional requirements, then the signal transmission path is lengthened, but transportation and installation costs increase
Solution Approach 1:
The strip line is divided into multiple transportable segments that can be moved and installed separately, then spliced together on-site. This segmentation reduces transportation costs by avoiding handling of a single long component and simplifies installation through modular assembly, while achieving the required functional length.
4Length of moving object
If the suspended strip line is extended to achieve functional requirements, then the signal transmission path is lengthened, but the length-width ratio increases causing fabrication inconsistency
Solution Approach 1:
The strip line is segmented into multiple sections with moderate length-width ratios that can be fabricated with consistent line widths using standard processes. Each segment maintains manageable dimensions for precise fabrication, and the segments are spliced together to achieve the required total length without compromising line width consistency.
Solution Approach 2:
The solution transitions from a single long strip line to multiple segments arranged in space. This allows the functional length requirement to be met through spatial configuration of multiple segments with consistent, manufacturable dimensions, rather than extending a single segment to excessive length-width ratio.

AI summary
This disclosure relates to a component of a radio frequency functional device. The component can be a suspended strip line or any structure including the suspended strip line, which includes a cavity and a strip line located in the cavity. The strip line includes a signal processing line, a plurality of power branch lines, and a connector. The signal processing line has one end conducted to a signal source and another end electrically connected to the plurality of power branch lines separately. A first power branch line includes a first segment and a second segment that are disconnected from each other. One end of the first segment is electrically connected to the signal processing line. The second segment is located at one end of the first segment away from the signal processing line. The connector is located between the first segment and the second segment, to implement signal transmission between the first segment and the second segment.
