Abstract :
We report on the design and performance of a fix-tuned ×2×3×3 frequency multiplier chain that covers 1.55-1.75THz. The chain is nominally pumped with 100mW at W-band. At 120K the measured output power is larger than 4μW across the band with a peak power of 100μW at 1.665THz. A similar chain operated at room temperature produced a peak power of 21μW. These power levels now make it possible to deploy multipixel heterodyne imaging arrays in this frequency range.
