Abstract: A radio frequency (RF) front end module includes an antenna node, a number of RF filtering elements and switching circuitry. Each one of the RF filtering elements is configured to pass RF signals within a filter pass band and attenuate RF signals outside the filter pass band. The switching circuitry is configured to selectively couple one or more of the RF filtering elements to the antenna node such that RF signals in different operating bands received at the antenna node are separately isolated by the RF filtering elements. The RF filtering elements include a shared filtering element, which is switchable such that in a first operating configuration is used to isolate signals within a first operating band and in a second operating configuration is used to isolate signals within a second operating band that is different from the first operating band.
