A model of a parallel metallic quantum nanotransistor with a Coulomb-blockage gate in “magic” nanocrystals Au55 and Ag55 with the speed of 1011 Hz having sizes of 100 × 100 × 12 nm3 is suggested and calculated. It is shown that the gate-opening threshold for this model with the source-drain potential of 2.74 V is 0.2 V, and the total current of 2500 elementary single-electron nanotransistors connected in parallel is 2 × 10−5 A, which is comparable with a current in terahertz semiconductor nanotransistors. It is shown that the charge amplification coefficient is K q ∼ 1, while the power amplification coefficient is K w ∼ 13. When using the inductive-capacitive load, a similar nanotransistor could be an element of an integrated circuit—radiation generator with wavelength λ = 3–6 mm and specific power of ∼104 W/cm2 with efficiency of ∼85–90%.
