The publication Test & Measurement World recently mentioned the 2.4 GHz Signal Source Kits developed by radio amateur and AMSAT-UK member David Bowman G0MRF.
The article says:
“Most simple DIY comb generators seem to run out of steam about 1 GHz. I recently ran into David Bowman’s 2.4 GHz circuit and measured an upper usable range of about 6 GHz. While greatly attenuated above 3 GHz, this circuit should still be valuable for measuring semi-anechoic chambers in the GHz ranges.”
