Manifold-coupled switched filter bank implementing filters with embedded switches

A switched filter bank with 2^N states for an N channel system is designed, fabricated, and tested. The design implements input and output manifold-coupled multiplexers with tunable filters. The bandwidth associated with a channel filter can be added or removed by actuating switches placed within the filter itself. This type of tuning allows for the switching of channel filters without affecting the other filters connected to the manifold. The concept is demonstrated using coplanar waveguide filters and diplexers.
