PAE / PDISS / TJ计算器

    步骤1：计算器件的功耗（Pdiss）

    如果已经知道你的Pdiss,  请在虚线下方输入。

    Inputs
    • Supply: Volts
    • Current: mA
    • Pin:
    • Pout:
    Outputs
    • DC Power: Watts
    • Gain: dB
    • Drain/Collector Efficiency: %
    • Power Added Efficiency: %
    • Power Dissipated In Device (Pdiss): Watts
    已经知道Pdiss值? Power Dissipated In Device (Pdiss): Watts

    步骤2：计算最大结温

    Inputs
    • Maximum Case (Tbase) Temperature: °C
    • Rth Junction To Case: °C/Watt

    注意:

    测量值会因应用和测量方法不同而有所不同。 最准确的数据可在产品数据手册中查找。

     

    Outputs
    • Max Junction Temperature: °C

    Formulas Used

    • DC Watts = Supply V × Current / 1000
    • Gain (dB) = Pout dBm - Pin dBm
    • Pin Watts = (10^(Pin dBm / 10)) / 1000
    • Pout Watts = (10^(Pout dBm / 10)) / 1000
    • Drain/Collector Efficiency % = (Pout Watts / DC Watts) × 100
    • PAE % (Low Gain < 25dBm) = (Pout Watts - Pin Watts) x 100 / (DC Watts)
    • Pdiss Watts = DC Watts + Pin Watts - Pout Watts
    • Temperature Change °C = Rth Junction to Case × Pdiss Watts
    • Max. Junction Temperature at max. Case Temp = Temp Change °C + max. Case Temp°C
    • Note: Tbase = interface between part and PC board/heatsink.
