V-band and W-band broadband, monolithic distributed frequency multipliers

Broadband V-band and W-band frequency multiplication is reported using soliton propagation on GaAs monolithic nonlinear transmission lines. With 24-dBm input, a doubler attained 17.4-dBm peak output power with at least 52-63.1-GHz 3-dB bandwidth, and a tripler attained 12.8-dBm peak output power with at least 81-108.8-GHz 3-dB bandwidth. These multipliers were fabricated with 3- mu m design rules on GaAs and driven with lower-frequency amplifiers, and are cost-effective sources of high-frequency power.<
