Ultra-wide IF bandwidth — The next frontier for SIS receivers
Edward Tong, Paul Grimes, Jonathan Weintroub, R. Blundell
Abstract
Tucker's theory of quantum mixing can be extended to model distributed series connected SIS mixers, which offer a lower capacitance and a higher dynamic range. These mixers have wider IF bandwidth than single junction mixer. Coupled with the emerging ultra-wide band technologies in low noise amplifier and fast digital signal processing, they open a new frontier of ultra-wide band receivers. We report on the development of the wideband SIS receivers for the Submillimeter Array, designed with Tucker's theory.
