Modular RF Power Amplifier and Combiner for Easy Band Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power amplification apparatuses for television signal transmission systems are integrated, making it impossible to separately exchange or standardize components for power amplification and signal combination, leading to inefficiencies and increased maintenance costs when frequency bands change or components fail.
Innovation Solution
A power amplification apparatus design where the amplification unit and combining unit are detachable through coaxial connectors, allowing for separate manufacturing and easy exchange of components, with the amplification unit containing multiple amplification circuits and the combining unit featuring multiple combiners to handle specific frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If power amplification and signal combination components are integrated in a single apparatus, then the system structure is compact and simple, but the components cannot be separately exchanged or standardized, increasing maintenance costs and downtime when components fail or frequency bands change
Solution Approach 1:
The patent divides the power amplification apparatus into separate functional modules: power amplification units and combining units. Each unit can be independently manufactured, tested, and exchanged. The power amplification unit contains amplification circuits while the combining unit contains combiners, and they are connected through detachable coaxial connectors, enabling modular replacement without affecting the entire system.
2Ease of manufacture
If power amplification and signal combination components are integrated in a single apparatus, then manufacturing is simpler, but standardization across different frequency bands becomes impossible, leading to increased costs when frequency bands change
Solution Approach 1:
The patent designs power amplification units with universal interfaces (coaxial connectors) that can be connected to different combining units supporting various frequency bands. This allows a single power amplification unit to serve multiple frequency band applications by simply changing the combining unit, achieving standardization and multi-functionality without redesigning the entire apparatus.
3Area of stationary object
If all components are housed in a single chassis, then the apparatus is compact, but maintenance requires accessing internal components deep within the chassis, increasing maintenance time and cost
Solution Approach 1:
The patent separates power amplification units and combining units into distinct modular components with detachable connections. This segmentation allows maintenance personnel to easily access and replace specific units by simply disconnecting the coaxial connectors, without needing to open or access the interior of a single large chassis, significantly improving maintenance accessibility.

AI summary
An amplification unit 1 has an output connector 3 for outputting an RF signal output by an amplification circuit 2 for each amplification circuit. The output connectors 3 are disposed so as to be arranged in the horizontal direction. A combining unit 5 has an input connector 6 into which the RF signal output from the output connector 3 of the amplification unit 1 is input for each output connector 3. The input connectors are disposed so as to be arranged in the horizontal direction. The amplification unit 1 and the combining unit 5 are attachable/detachable through the output connectors 3 and the input connectors 6. The surface on which the input connectors are provided of the combining unit 5 is set within the dimension of the surface on which the output connectors are provided of the amplification unit 1.
