Low diode capacitance is also important to prevent feedthrough. Faster
designs use more than one diode and a second inverted pulse to
compensate for charge delivered through the diode's junction
capacitance. Tektronix did this in their reference level pulse
generators intended for 1 GHz oscilloscope calibration.
Hey David,
would you happen to be able to point to a schematic of such a thing?

Take a look at the schematics for the 7000 series standardizers, the
PG506, and the Type 106 square wave generator.
I can host the documentation to the NBS design if you would like to
see it as well.
