Junction Temperature

P_{diss} = \frac{P_{out}}{Efficiency} - P_{out}

P_{diss} = P_{dc} - P_{out}

Δ T = R_{th} \cdot P_{diss}

P_{mW} = 10^{(\frac{P_{dBm}}{10})}

T_{j} = T_{case} + Δ T

Calculation of R_th

P_{diss} = \frac{P_{out}}{Efficiency} - P_{out}

P_{diss} = P_{dc} - P_{out}

R_{th} = \frac{Δ T}{P_{diss}}

Δ T = T_{j} - T_{case}

Min Efficiency at Max T_j

Δ T = T_{max} - T_{case}

max P_{diss} = \frac{Δ T}{R_{th}}

P_{dc} = P_{diss} + P_{out}

min Efficiency = \frac{P_{out}}{P_{dc}}

Thermal Efficiency

PAE = \frac{P_{out}}{(P_{in DC} + P_{in RF})}

Drain Eff = \frac{P_{out}}{P_{in DC}}

Efficiency = PAE + Drain Eff
