HiWe use the HMC733 VCO.
I have a question.
1. The frequency was 9.7 GHz. If we watched it for 1 hour, we could see that it was moved to the left little by little.At 18GHz, the frequency will continue to move to the right.This is the case with the Frequency Drift Rate parameter.The question here is that the frequency stops and shifts little by little. Why does the frequency continue to shift after 2 hours and 3 hours? Could you help me? Thank you.
The frequency of any free running (e.g. not phase locked) signal on a microwave VCO will drift; this is mostly due to temperature. Many of the HMC series VCO's are mounted to an aluminum backer plate…
