ADL5902 Vout calculation

Hi ,

I have doubt in calculating the Vout of ADL5902. I calculated Vout using this formulae (VOUT = VSLOPE × log10(RMS(RFIN)/VZ))

Whereas Vslope=38.3mV, RMS(RFIN)= 223.607 mV(0dBm), Vz=0.8.


For above assumption I expect output voltage  of 2.49V.but I didn’t get proper output value.  If possible can you please explain how to calculate

1)Intercept voltage (Vz) for frequency range of 400MHZ to 6GHZ
