Exact Mathematical Derivation for +45 dBm
Step 1: P(mW) = 10^(45 / 10) = 10^(4.50) = 31,622.777 mW
Step 2: P(W) = 31,622.777 mW ÷ 1,000 = 31.623 Watts
Step 3: V_RMS (@ 50Ω) = √(3.162e+1 W × 50 Ω) = 39.7635 V RMS (152.0 dBμV)
Step 2: P(W) = 31,622.777 mW ÷ 1,000 = 31.623 Watts
Step 3: V_RMS (@ 50Ω) = √(3.162e+1 W × 50 Ω) = 39.7635 V RMS (152.0 dBμV)
