Abstract :
The single-sideband FM noise characteristics of IMPATT diode oscillators for D-band frequencies have been measured by means of a direct-detection system with a high-Q quasi-optical resonator. For an n-type silicon single-drift IMPATT diode a ¿frms of 11 Hz/¿Hz and a noise measure of 37 dB at 137.5 GHz and 26 mW output power was determined.
