  • 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.
