ADAR2001 ADC Code from RF Detector conversion table

I'm checking to see what data we have on ADC_Code vs output power and will get back to you once I get some data. - Eamon

Here is some data showing ADC code on the y-axis vs output power and output voltage on the x-axis. Because it's a diode-based detector, you need to plot ADC Code vs Vrms to get a straight line that you can then model as y=mx+c. If you do this, you get nice straight lines. You can also get a straight line plot if you plot ADC Code(logarithmic on the y-axis) vs ADAR2001 output power in dBm.

There is a lot of variance vs frequency. So you will have to calibrate the detector vs freq in addition to vs RF power level.

You will notice that at two frequencies, the RF power range is very low. The measurements were taken by sweeping input power and measuring output power and ADC code. The signal chain from input to output is non linear. So at some frequencies, the output power is close to saturation for all input power levels. This is where the narrow range comes from. However, the data at these frequencies still shows the expected behavior in terms of ADC code vs output power.  

All the best
