Abstract
Resonant tunneling diodes, which have the highest operating frequencies among solid‐state oscillating devices at millimeter and submillimeter wave frequencies, generate spurious low‐frequency oscillations easily. As a method of suppressing spurious oscillation of negative resistance devices, the oscillation devices may be connected in series. In this paper, this approach is applied to resonant tunneling diodes. If two diodes are connected in series, no spurious oscillation is observed in the oscillation output spectrum. The effect of suppression of spurious oscillation is experimentally confirmed. Further, from the output characteristic, it is found that the devices are useful as low‐noise high‐ frequency amplifiers and frequency multipliers. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 84(12): 17–25, 2001
