Exact Mathematical Derivation for +55 dBm
Step 1: P(mW) = 10^(55 / 10) = 10^(5.50) = 316,227.766 mW
Step 2: P(W) = 316,227.766 mW ÷ 1,000 = 316.228 Watts
Step 3: V_RMS (@ 50Ω) = √(3.162e+2 W × 50 Ω) = 125.7433 V RMS (162.0 dBμV)
Step 2: P(W) = 316,227.766 mW ÷ 1,000 = 316.228 Watts
Step 3: V_RMS (@ 50Ω) = √(3.162e+2 W × 50 Ω) = 125.7433 V RMS (162.0 dBμV)
