And how does it vary with temperature?
Below is the HMC849ALP4CE group delay plot generated from the de-embedded s-parameter data taken at +25C only.
Average group delay over a frequency range from 100MHz to 6GHz is about 70ps .
The group delay variation over full temperature range from -40C to +85C is less than +/-5ps based on the over temperature measurement data that includes the board losses as well.
