Abstract
A wide bandwidth multiplexer (MUX) is provided that performs carrier aggregation. The MUX combines at least a first LC filter that acts as a low band filter, at least a first composite filter that acts as a middle band filter, and at least one other LC or composite filter that acts as a high band filter. The wide bandwidth MUX has low insertion loss and provides sufficient attenuation at adjacent edges of adjacent pass bands to prevent overlap between adjacent pass bands.
