Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed power source radio frequency power supply mode is adopted, then the power supply is stable and simple to implement, but it cannot be flexibly adjusted and switched, resulting in low anti-interference performance
Solution Approach 1:
The patent implements dynamic power supply adjustment by enabling the radio frequency power amplifier to switch between multiple power supply modes (bypass mode, average power tracking mode, enhanced power tracking mode, and envelope tracking mode) based on real-time operating conditions. This transforms the static fixed power supply into a dynamic adaptive system that can respond to changing interference environments and power consumption requirements.
Solution Approach 2:
The patent changes the power supply parameters (voltage and current characteristics) by selecting different power supply modes. Each mode provides distinct electrical characteristics: bypass mode provides direct connection, APT provides average power tracking, EPT provides enhanced tracking, and ET provides envelope tracking. These parameter changes enable adaptation to different operating conditions while maintaining system stability.
2Power
If high power is used to ensure large power output and improve transmission modulation performance, then transmission performance is improved, but power consumption and heat generation increase
Solution Approach 1:
The patent dynamically adjusts the power supply characteristics to match the actual power requirements of the radio frequency power amplifier. By switching between bypass mode (for high power output) and tracking modes (for reduced power consumption), the system optimizes the balance between power output and energy consumption based on real-time operating conditions.
Solution Approach 2:
The patent changes the power supply voltage and current parameters by selecting different operating modes. The envelope tracking mode provides precise voltage modulation to match the signal envelope, reducing unnecessary power consumption while maintaining required power output. The average power tracking mode adjusts parameters based on average power levels, and enhanced power tracking provides intermediate optimization.
3Reliability
If high power is used to improve transmission modulation performance, then transmission quality is improved, but interference by the power source increases
Solution Approach 1:
The patent dynamically selects power supply modes to minimize interference while maintaining transmission performance. The system monitors operating conditions and switches between bypass mode (for high power requirements) and tracking modes (for reduced interference), enabling adaptive suppression of power source interference during transmission.
Solution Approach 2:
The patent changes power supply parameters through mode selection to reduce interference. The envelope tracking mode provides precise voltage control that minimizes spectral regrowth and adjacent channel leakage, reducing interference. The average power tracking mode adjusts parameters to reduce power source noise, and enhanced power tracking provides optimized parameter control for interference reduction.
