Abstract
Front-end architecture having quadplexer for carrier aggregation and MIMO support. In some embodiments, a front-end architecture can include a quadplexer configured to support uplink carrier aggregation with a first antenna. The quadplexer can include a low-band filter, a mid-band filter, a first high-band filter, and a second high-band filter, with each filter having a respective input node, and the quadplexer including a common output node associated with the first antenna. The front-end architecture can further include a triplexer configured to support uplink carrier aggregation with a second antenna. The triplexer can include a mid-band filter, a first high-band filter, and a second high-band filter, with each filter having a respective input node, and the triplexer including a common output node associated with the second antenna.
