Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tower mounted amplifiers require a large number of filters for each frequency band, leading to increased volume and costs, making them less efficient and more cumbersome for supporting multiple frequency bands.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more frequency bands are processed, then the adaptability of the tower mounted amplifier is improved, but the quantity of filters increases leading to increased volume and costs
Solution Approach 1:
The patent applies universality by designing a single tower mounted amplifier that can process multiple frequency bands (e.g., Band 8, Band 20, Band 28) using a shared filter structure. Instead of requiring separate amplifiers or dedicated filters for each frequency band, the invention enables one amplifier to universally handle multiple bands through configurable filter settings and a shared signal path, thereby reducing the overall quantity of filters and amplifier units needed in the system.
Solution Approach 2:
The patent merges the filter structures for different frequency bands into a single integrated tower mounted amplifier unit. By combining multiple frequency band processing capabilities into one device with shared components (amplifier, power supply, housing), the invention reduces the total volume compared to having separate amplifiers for each band. The filter bank is consolidated within a single device rather than distributed across multiple devices.

3Reliability
If a separate amplifier is used for each frequency band, then the signal processing quality is improved, but the device complexity and quantity of components increases
Solution Approach 1:
The patent applies segmentation by dividing the signal processing path into distinct stages: a filter bank that separates different frequency bands, followed by a shared amplifier. Each frequency band can be filtered independently through specific filter elements in the bank, maintaining signal quality for each band, while the amplification function is shared across all bands. This segmented approach allows quality maintenance without requiring separate complete amplifier units for each band.

The patent applies universality by designing a single tower mounted amplifier that can process multiple frequency bands (e.g., Band 8, Band 20, Band 28) using a shared filter structure. Instead of requiring separate amplifiers or dedicated filters for each frequency band, the invention enables one amplifier to universally handle multiple bands through configurable filter settings and a shared signal path, thereby reducing the overall quantity of filters and amplifier units needed in the system.
