Abstract :
A tuner-less heterostructure barrier varactor (HBV) frequency tripler has been designed, fabricated, and tested. A conversion efficiency of 7.2% and output power of 6.5 mW were measured at 270 GHz with 90 mW of input power. The performance of this tuner-less HBV tripler is comparable with other HBV frequency multipliers reported in the literature that utilize mechanical tuners to optimize their performance
