Abstract :
We have designed, fabricated and characterized a heterostructure barrier varactor based monolithic tripler at 97 GHz. The original InP host substrate is used as the microstrip waveguide. Measurement results show efficiencies of almost 20% and a maximum output power of 85 mW. Initial comparison with hybrid (flip-chip) solutions imply that the monolithic approach has superior performance.
