TX MIMO Power Manager Layout for Independent Amplifier Voltage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices are inefficient in performing uplink carrier aggregation and uplink MIMO transmissions due to the inability to independently power different amplifiers within the same transmitter with different voltages, leading to suboptimal power management.
Innovation Solution
A communication device is configured with separate power managers for low and high band amplifiers in both main and MIMO transmitters, allowing the control system to provide distinct power voltages to each amplifier, enabling efficient power management by optimizing voltage supply based on amplification requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a dedicated power manager powers all amplifiers in the same transmitter simultaneously, then the transmitter structure is simplified, but the ability to independently control power voltage for different amplifiers is lost
Solution Approach 1:
The patent segments the power management function by providing separate power managers for different amplifiers (e.g., first power manager for first amplifier, second power manager for second amplifier). This allows each amplifier to be independently controlled in terms of power supply, enabling adaptive power management where each amplifier can receive appropriate power voltage based on its specific requirements without being constrained by a unified power manager.
Solution Approach 2:
The patent implements local quality by allowing different power voltages to be supplied to different amplifiers based on their specific needs. Each amplifier can receive a power voltage level optimized for its operating conditions, frequency band, and signal requirements, rather than being forced to use a uniform power level across all amplifiers in the transmitter.
2Device complexity
If the same power voltage is supplied to all amplifiers, then the power management system is simpler, but power consumption efficiency deteriorates
Solution Approach 1:
The patent introduces dynamic power management by enabling independent control of power voltages supplied to different amplifiers. Each amplifier's power voltage can be dynamically adjusted based on real-time operating conditions, signal requirements, and frequency bands, allowing the system to optimize power consumption by supplying only the necessary power to each amplifier rather than using a fixed uniform voltage.
Solution Approach 2:
The patent changes the power voltage parameter independently for each amplifier based on its specific requirements. By allowing different power voltage levels to be supplied to different amplifiers simultaneously, the system can optimize power consumption efficiency while maintaining the ability to support various operating modes including carrier aggregation and MIMO transmissions.
3Power
If high power voltage is supplied to all amplifiers simultaneously, then transmission capability is improved, but power consumption increases unnecessarily
Solution Approach 1:
The patent applies partial action by supplying high power voltage only to the specific amplifiers that require it for their current operation, rather than supplying high power to all amplifiers simultaneously. This allows the system to maintain high transmission capability when needed while avoiding unnecessary power consumption in amplifiers that operate at lower power levels, thereby optimizing the balance between transmission performance and energy efficiency.
