Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional assembly of a low-noise block converter and a filter for satellite antenna systems experiences interference due to insufficient closeness between components and a long ground signal path, leading to signal loss during transmission.
Innovation Solution
A connecting component with a conductive sleeve part and core, threaded for engagement between the low-noise block converter and filter, serves as both a grounding medium and a shorter ground path, ensuring closeness and reducing signal loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screws are used to fasten the low-noise block converter to the filter, then the components are connected, but the components are not close enough together causing external interference
Solution Approach 1:
The patent merges the fastening function and the grounding function into a single integrated connecting component. The threaded sleeve serves both to mechanically secure the low-noise block converter to the filter and to provide a continuous grounding path, eliminating the need for separate screws and reducing the number of connection points where interference could occur.
Solution Approach 2:
The connecting component performs multiple functions simultaneously: it acts as a mechanical fastener (threaded engagement), an electrical ground path (conductive material), and a spacing element (sleeve structure). This multi-functionality resolves the contradiction by providing both secure connection and interference protection through a single component design.
2Reliability
If conventional connecting components with dielectric layers are used, then signal transmission is enabled, but the ground signal path becomes too long causing signal loss
Solution Approach 1:
The patent extracts the dielectric layer from the connecting component, eliminating it entirely. By removing the insulating material that forced the ground signal to take a long path through external screws and mounting structures, the ground signal can now travel directly through the conductive threaded sleeve, significantly shortening the ground path and reducing signal loss.
Solution Approach 2:
The threaded sleeve acts as an intermediary grounding element that provides a direct conductive path between the low-noise block converter and the filter. This intermediary structure replaces the long external ground path with a short internal ground path through the connecting component itself, reducing signal loss while maintaining electrical isolation where needed.

AI summary
An assembly of a low-noise block converter and a filter for a satellite antenna includes a low-noise block converter, a filter, and a connecting component. The low-noise block converter includes an output circuit, and the filter includes a filtering circuit. The connecting component includes a sleeve part for engaging threadedly the low-noise block converter and the filter, and a core extending through the sleeve part and interconnecting electrically the output circuit and the filtering circuit. By virtue of the sleeve part of the connecting component, connection between the low-noise block converter and the filter can be reinforced to reduce interference. The sleeve part can also serve as a ground circuit between the low-noise block converter and the filter so as to shorten a ground path, thereby reducing signal loss.
