Broadband V-band and W-band frequency multiplication is reported using soliton propagation on a GaAs monolithic device. With 24-dBm input, a doubler attained 17.4-dBm peak output power with at least a 52-63.1-GHz, 3-dB bandwidth, and a tripler attained 12.8-dBm peak output power with at least a 81-108.8-GHz, 3-dB bandwidth. These multipliers, fabricated with 3- mu m design rules on GaAs and driven by lower-frequency amplifiers. have applications as cost-effective sources in millimeter-wave systems.
