Abstract
Tunnel diodes have been made to operate above their resistive cutoff frequency by mounting them in tapered waveguides. The output is apparently due to harmonics of a lower frequency oscillation. The fundamental frequency was detected by means of a probe placed close to the diode. Examination of the diode´s equivalent circuit indicates that it is unlikely that oscillations can occur above the resistive cutoff frequency.
