Vout (no RF Input)

Question

Hello AD team, 
 I am using LTC5507 in my design, and I am using the value of the output voltage when there is no RF input, to detect whether an antenna is connected or not. 
 I would like to understand if the output voltage while no RF input exists, is sensitive to time or temperature, for the same device. 
 In other words, assuming that I measured an output of 250mV today, could this value change over a day/month/year? And in case that the ambient temperature was changed? 
 Please share data if you have. 
 Your quick reply will be very appreciated. Thank you

We do not have long term drift data on LTC5507. However, I do not expect the no RF output voltage to change very much, probably < 50mV. The variation over temperature is minimal:)
