Exact Mathematical Derivation for +46 dBm
Step 1: P(mW) = 10^(46 / 10) = 10^(4.60) = 39,810.717 mW
Step 2: P(W) = 39,810.717 mW ÷ 1,000 = 39.811 Watts
Step 3: V_RMS (@ 50Ω) = √(3.981e+1 W × 50 Ω) = 44.6154 V RMS (153.0 dBμV)
Step 2: P(W) = 39,810.717 mW ÷ 1,000 = 39.811 Watts
Step 3: V_RMS (@ 50Ω) = √(3.981e+1 W × 50 Ω) = 44.6154 V RMS (153.0 dBμV)
