Abstract
Front-end architecture having split diplexers for carrier aggregation and MIMO support. In some embodiments, a multiplexing architecture can include an assembly of filters configured to support carrier aggregation with one or more antennas. The assembly of filters can include a first diplexer configured to support a mid-band and a first high-band. The assembly of filters can further include a second diplexer configured to support the mid-band and a second high-band. The multiplexing architecture can further include a switch assembly implemented between the assembly of filters and respective one or more nodes associated with the one or more antennas.
Claims20
A multiplexing architecture comprising:
- an assembly of filters including a first multiplexer that includes a mid-band filter configured to support a mid-band and a first high-band filter configured to support a first high-band, and a second diplexer multiplexer that includes a mid-band filter configured to support the mid-band and a second high-band filter configured to support a second high-band, each of the first and second high-band filters configured to support a respective frequency range that is smaller than a frequency range associated with a high-band filter of a single multiplexer that supports both of the first high-band and the second high-band;
- and
- a switch assembly implemented between the assembly of filters and one or more antenna nodes.
A packaged module for wireless applications, comprising:
- a packaging substrate configured to receive a plurality of components;
- and
- a multiplexing circuit implemented on the packaging substrate, and including an assembly of filters including a first multiplexer that includes a mid-band filter configured to support a mid-band and a first high-band filter configured to support a first high-band, and a second diplexer multiplexer that includes a mid-band filter configured to support the mid-band and a second high-band filter configured to support a second high-band, each of the first and second high-band filters configured to support a respective frequency range that is smaller than a frequency range associated with a high-band filter of a single multiplexer that supports both of the first high-band and the second high-band, the multiplexing circuit further including a switch assembly implemented between the assembly of filters and one or more antenna nodes.
A wireless device comprising:
- a transceiver;
- a plurality of antennas each configured to support either or both of transmit and receive operations;
- and
- a multiplexing architecture implemented between the transceiver and the plurality of antennas, and including an assembly of filters including a first multiplexer that includes a mid-band filter configured to support a mid-band and a first high-band filter configured to support a first high-band, and a second diplexer multiplexer that includes a mid-band filter configured to support the mid-band and a second high-band filter configured to support a second high-band, each of the first and second high-band filters configured to support a respective frequency range that is smaller than a frequency range associated with a high-band filter of a single multiplexer that supports both of the first high-band and the second high-band, the multiplexing circuit further including a switch assembly implemented between the assembly of filters and one or more of the plurality of antennas.
