Do you have a sample circuit for a noise generator that goes an octave or two higher??
Would you be willing to speculate on stripline / SMD construction techniques to go up to or past 1 GHz?? My guess is -- duplicate the schematic with SMDs and use some common microwave transistors like MRF901.

I want to test filters and once again Santa stiffed me on all the fancy test gear I wanted.? It could be my fault as my chimney leads to the boiler.? Anyway, I have an rtl-sdr and an upconverter so all I needed was some clean noise.? Searching lead me to N5ESE's description of using a zener diode.? He references an earlier design by N0SS.? N0SS is now SK and his website is no longer but thanks to I found this
