AD9361 Calibration Requirements with Temperature Change

Question asked by gizmoaudio on Jul 2, 2015

We are operating in FDD mode. When there are large temperature changes, which calibrations need to be re-done? The data sheets indicate that Synthesizer cals such as charge pump and VCO cals only need to be done at initialization. If there are large temperature changes, do these need to be re-calibrated? If so, are there any guidelines as to how much temperature change before a cal is required?
