Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional dual band bidirectional amplifiers are constructed from two single band bidirectional amplifiers connected by two power dividers, then signal coverage for two frequency bands is provided, but power loss and gain loss increase significantly
Solution Approach 1:
The patent combines two separate single-band amplifier systems into a single integrated dual-band amplifier architecture. By merging the power amplifier, duplexers, and signal paths into one unified system, the invention eliminates the need for separate power dividers that caused significant power loss. The shared power amplifier and optimized signal routing reduce overall power loss while maintaining dual-band coverage capability.
Solution Approach 2:
The patent implements a universal power amplifier that can operate across multiple frequency bands simultaneously. This multi-functional amplifier replaces the need for separate single-band amplifiers and power dividers, providing both frequency bands through a single device. The universal design reduces component count and eliminates the power loss associated with multiple power division stages.
2Adaptability or versatility
If conventional dual band bidirectional amplifiers use two power dividers to provide signal paths for two frequency bands, then dual band coverage is achieved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple discrete components (two single-band amplifiers, two power dividers, multiple duplexers) into a single integrated dual-band amplifier system. This consolidation reduces device complexity by eliminating redundant components and simplifying the overall architecture while maintaining dual-band operational capability.
Solution Approach 2:
The invention employs universal components that can handle multiple frequency bands, such as a wideband power amplifier and strategically placed duplexers. This multi-functional approach reduces the number of band-specific components needed, thereby reducing device complexity and cost while achieving dual-band coverage.
3Adaptability or versatility
If conventional dual band bidirectional amplifiers connect two single band bidirectional amplifiers with power dividers, then two frequency bands are transmitted and received, but noise increases
Solution Approach 1:
By combining the signal paths into a single integrated system rather than using separate amplifier chains, the patent reduces the number of active components that generate noise. The merged architecture minimizes noise accumulation while maintaining the ability to transmit and receive on two frequency bands simultaneously.
4Adaptability or versatility
If conventional amplifiers use multiple components for dual band operation, then multiple frequency bands are supported, but operating costs increase
Solution Approach 1:
The patent combines multiple amplifier functions into a single power-efficient architecture. By sharing the power amplifier and optimizing the signal path, the system reduces overall power consumption compared to running separate amplifiers for each band, thereby lowering operating costs while supporting multiple frequency bands.
