Abstract:We report on the design and MBE-growth of heterostructure barrier varactor (HBV) diode materials. The quality and performance of in-house HBV materials are presented. The design methodology and electro-thermal simulations of high power HBV multipliers for signal generation in the frequency range 100 -300 GHz are also presented. Finally, a state-of-the-art tripler efficiency of 21% and a quintupler efficiency of 11% for W-band multipliers have been demonstrated.Index Terms -Heterostructure barrier varactor, Fre… Show more
