Abstract :
Experimental results on the noise behaviour of a double barrier resonant tunnelling (DBRT) diode are presented. The measurement method had been developed from a standard noise figure meter calibration procedure. Measurements were performed on a stabilised DBRT diode, mounted in a reflection amplifier configuration. The actual circulator in the setup is represented by an ideal circulator and two error networks. Noise figure and noise measure of a DBRT diode at 1 and 1.5 GHz are reported. The bias voltage range includes two positive-conductance regions as well as the intermediate negative-conductance region. In the active region of a 20 mu m mesa diameter DBRT diode, the lowest noise measure observed was 5.5.
