A balanced, dual-diode varactor frequency doubler for 85-116 GHz is described and its performance compared to that of a single-diode device. The balanced doubler can provide a minimum of 18 mW between 85 and 116 GHz for 190-mW maximum safe input power, while the single-diode doubler using the same diode-type exhibits a minimum output power of 10 mW over the same frequency range for a maximum safe input power of 90 mW. An improved single-diode design using a higher breakdown voltage diode has achieved a minimum output power of 18 mW between 97 and 116 GHz for a maximum safe input power of 150 mW. These devices have been used in cascade with a frequency tripler to implement a 6 x multiplier chain to 310-350 GHz with a minimum output power in this submillimeter band of 0.6 mW.
