Abstract
Described herein are systems, devices, and methods for a multi-standard radio switchable multiplexer that is configured to process wireless local area network (WLAN) signals and cellular signals in the same module. A front end module can be configured to support concurrent operation of WLAN signals and cellular signals using switching networks as described herein. In general, the described systems and methods can be configured to concurrently operate different radio systems (e.g., cellular, BLUETOOTH, WLAN, GPS, etc.) without the use of cascaded filters.

A reconfigurable multiplexer comprising:
- a switching network including multi-path operability and connectability to a signal port;
- a first filter implemented between the switching network and a first bi-directional port that is associated with a first radio access network, the first filter configured to pass a first cellular frequency band that corresponds to the first radio access network;
- a second filter implemented between the switching network and a second bi-directional port that is associated with a second radio access network, the second filter configured to pass a wireless local area network frequency band that corresponds to the second radio access network;
- a third filter implemented between the switching network and a third bi-directional port that is associated with a third radio access network, the third filter configured to pass a second cellular frequency band that corresponds to the third radio access network, the wireless local area network frequency band being between the first cellular frequency band and the second cellular frequency band;
- a controller implemented to control the switching network to provide a respective signal path between the signal port and each of either or both of the first bi-directional port and the second bi-directional port, the switching network configured to couple any combination of the first filter, the second filter, and the third filter to the signal port simultaneously.
