Webb1 jan. 1992 · The oscillations in the ranges 75 - 260 GHz have been experimentally observed. The values of the generated power have been calculated from the amplitudes of the quasiparticle and Shapiro steps on the I-V curve of the detector junctions. The detected power levels higher than 0.1 /2W have been obtained. WebbOrdinary mixers can hardly meet the requirements in terahertz (THz) communications due to the low-power and expensive THz sources. Sensitive harmonic mixers have been widely studied to avoid this problem, owing to the fact that the higher the number of harmonics, the lower the local oscillator (LO) frequency, and the lower the cost.
