Abstract
The present application provides a radio frequency front end circuit, a wireless communication device and a method for coupling signals in support of multiple input and multiple output, and carrier aggregation for multiple frequency bands of operation between one or more transceivers and a plurality of antennas. Each antenna is associated with a respective signal from each of a first frequency band of operation and a second frequency band of operation from the one or more transceivers. The radio frequency front end circuit includes a multi-close front end switch associated with one of the plurality of antennas, where separate terminals of the multi-close front end switch are each respectively associated with the respective signal from each of the first frequency band of operation and the second frequency band of operation corresponding to the associated antenna from the one or more transceivers. The separate terminals of the multi-close front end switch can be simultaneously coupled to a port coupled to the associated antenna via multiple throws within the multi-close front end switch.
