AD9361 Temperature Behavior

Question asked by fischer on Mar 9, 2017

I have following question: Are there any functions inside the AD9361, which change the TX Monitor or TX behavior dependent on the chip temperature?

We use the AD9361 with TX monitor connected to the TX port. When we heat up or cool down the chip in temperature tests, we see a phase and gain change. On the one hand, we see continuous changes, which are logical explainable.  But on the other hand we see 2 jumping gain and phase changes in the temperature range of 85 °C.

 

Is there any compensation or non continuous effect going on in the AD9361, which depends on temperature levels?
