1Power
If the power supply voltage output from the tracker circuit is increased to support high power class signals, then the power output capability is improved, but the efficiency of the tracker circuit decreases and excessive heat is generated
Solution Approach 1:
The single tracker circuit and single power amplifier are segmented into multiple tracker circuits (first tracker, second tracker) and multiple power amplifiers (first power amplifier, second power amplifier). This segmentation allows the power supply voltage to be distributed across multiple components, preventing any single tracker from bearing excessive load and maintaining efficiency while achieving high power output capability.
2Power
If the power supply voltage output from the tracker circuit is increased to support high power class signals, then the power output capability is improved, but heat generation increases leading to decreased efficiency
Solution Approach 1:
The system is divided into multiple tracker circuits and power amplifiers, distributing the power generation and heat production across multiple components. This segmentation prevents excessive heat concentration in a single component, allowing for better thermal management while maintaining high power output capability.
