Abstract

Tiled filters are disclosed. A filter includes an n×m array of sub-filters, where n is a number of sub-filters in parallel and m is a number of sub-filters in series. n and m are non-zero positive integers and at least one of n and m is greater than one. All of the nm sub-filters are bandpass filters with substantially the same passbands.
