<p>A multi-band filter (10) comprising: an input manifold (12); an output manifold (18); and a plurality of filters (13,14,15,16) connected in parallel between the input manifold (12) and output manifold (18). The filters (13,14,15,16) have a first section proximal to the input manifold which is matched to the input manifold and a second section proximal to the output manifold which is matched to the output manifold.</p> |
