One option John Larjkin doesn't seem to have explored is using Renesas
HFA3096 five transistor array as basis for his mononstable and level
shifter.
 
It offers three 8GHz NPN parts and two 5.5GHz PNP parts in a single array.

Two of the NPN parts could make up my emitter-coupled monostable, and
the two PNP parts could level shift the output.
 
The Renesas website offers Spice models for both the NPN and the PNP
transistors, which one could plug into an LTSpice simulation, at the
cost of making it look too messy for the more sensitive designers to be
able to look at.

 
I've spent that last four days in hospital with Covid-19 of the colon -
dramatic when it started but tedious thereafter.
 
This thread hasn't gone all that well. John Larkin has ignored the fact
that I was talking about just the 3096. There have been some sensible
comments, but I'm still too sick to try and provide any kind of summing
up of the sensible bits.

OK, we can defer discussing your one-shot circuit until you feel
better. I've had some medical adventures of my own.
 
 

My sympathies to both of you, coincidentally I am just getting back on my
feet after an eight day common cold from hell (was not Covid)
