Abstract :
This paper discusses the construction of solid-state frequency multiplier chains utilized for terahertz receiver applications such as the Herschel Space Observatory. Emphasis is placed on the specific requirements to be met and challenges that were encountered. The availability of high power amplifiers at 100 GHz makes it possible to cascade frequency doublers and triplers with sufficient RF power to pump heterodyne receivers at THz frequencies. The environmental and mechanical constraints are addressed as well as reliability issues.
