BROADBAND NOISE SOURCE

noise generatorSearching the web for broadband noise sources (for use in noise figure measurements) I came across this implementation which utilized a BFR92 transistor. My final result was promising with the source having an ENR in the order of 25dB at 2m and 70cm. Its output was audible up to 10.368GHz (using my 3cm transverter, a video can be found here). A calibration against another calibrated noise source is needed now!
