Hi Jack,
The RF settling time to 0.1dB of final RF settled value on the HMC7992 was measured to be ~320ns.This measurement was made in a 50 Ohm system using our evaluation board employing 50 Ohm RF traces. After this time, the RF signal holds steady.
I would like to review certain application details. Please check your inbox for further communication.
Thanks,
HK.
