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.
Claims14
A filter comprising:
- an n×m array of sub-filters, where;
- n is a number of sub-filters in parallel,
- m is a number of sub-filters in series,
- n and m are non-zero positive integers,
- at least one of n and m is greater than one, and
- all of the nm sub-filters are bandpass filters with substantially the same pass-bands;
- and
- a filter input connected to inputs of n sub-filters of the nm sub-filters,
- wherein an input of each of the n sub-filters is approximately matched to nZs, where Zs is a system source impedance.
