Dew Point Calculation and Monitoring Strategy for Condensation Prevention in PA Equipment

PA (Power Amplifier) equipment generates significant heat during high-power operation, making cooling systems essential. However, during cooling, moisture in the air can condense, leading to serious damage to internal circuits. The key strategy to prevent this is dew point calculation and monitoring . In this article, we explain the meaning of the dew point, its application to PA equipment, and how to design a smart monitoring system. The dew point is the temperature at which moisture in the air begins to condense into water droplets. When the cooling surface temperature falls below the dew point, condensation occurs. Therefore, dew point management is vital in PA equipment cooling design.     Why Dew Point Management is Critical for PA Equipment Prevent short circuits from condensation : Protect RF modules and PCB circuits Extend equipment life : Prevent corrosion and insulation degradation Enable precise cooling design : Avoid unnecessary overcoo...
