Scientific paper

This paper describes the design and construction of a filterbank of novel design which uses sections of coaxial transmission line as filter elements. This filterbank is a lower cost alternative to standard (solid-state) filterbank designs, and is appropriate in situations where large total bandwidths are required, as is the case for submillimeter observations of extragalactic objects.
