F.m. noise of low-level-operating IMPATT-diode oscillators
Jasper J. Goedbloed · Electronics Letters · 1971
An analytical relationship for the output-spectrum width of a low-level-operating IMPATT-diode oscillator is verified experimentally by measuring relevant diode and circuit quantities as well as the oscillator noise. Good agreement between theory and experiment is found if the spectrum width is assumed to be predominantly due to f.m. noise.
