HMC601 Vlogout

Hi all,

I have a question about the function of HMC601 Log Detector.

Actually, I am verifying the function of the detector by checking the following:

1) In detector mode, the Vset pin is connected to the Vlogout pin where the obtained voltage values (0.6 to 2 V) for different Input signal levels (-75 to +5 dBm) are accurate and look like the values in the datasheet.

2) In controller mode, the Vset receives a voltage of 0.9V through a voltage divider. But for different input signals ranging from -75 to 5 dBm, Vlogout ranges from 4.8 to 4.9 V only.

Are the results in controller mode accurate? Since I expected a value for Vlogout equal to that applied to Vset pin.

Thanks for your valuable answer.
