At 2.6 GHz the relationship between input voltage and output voltage is as follows.

Vrms = (Gain x Vin) + Intercept

where Gain = 2.04 and Intercept = 0.015 V (from 2.6 GHz spec table)

If you want an equation that relates the ADL5511's output voltage to input power in dBm, you get

Pin (dBm) = 10 log( (1000/50) x sqr((Vrms-Intercept)/Slope) )

where 50 is the characteristic impedance.

It is important to note the the specified slope and intercept numbers above are typical and will vary from device to device. This means that each device should be calibrated to establish the exact value for its slope and intercept.
