HMC799 Overdrive Recovery Time

When evaluating the HMC799 TIA on a custom PCB (not AD Eval PCB) I have been observing
overdrive recovery times of ~30ns at the output when the input is overdriven by
a 20mA pulse. Is this what would be expected? The trace on page 11 of the data
sheet suggests overdrive recovery times significantly less than 30ns. Our
application requires overdrive recovery times of no more than a few ns.
