    Abstract: Circuitry includes an input node, an output node, acoustic filtering circuitry, an inductive element, and a capacitor. The acoustic filtering circuitry includes an acoustic filtering input node and an acoustic filtering output node. The inductive element is coupled in series with the acoustic filtering circuitry between the input node and the output node such that the inductive element is coupled between the input node and the acoustic filtering input node and the acoustic filtering output node is coupled to the output node. The capacitor is coupled in parallel with the acoustic filtering circuitry and the inductive element between the input node and the output node. Providing the inductive element in series with the acoustic filtering circuitry and the capacitor in parallel with the acoustic filtering circuitry and the inductive element provides a highly selective notch filter response between the input node and the output node with high attenuation.

    Abstract: RF front end circuitry includes at least three antennas, RF filtering circuitry, antenna switching circuitry coupled between the antennas and the RF filtering circuitry, and transceiver circuitry coupled to the RF filtering circuitry. The RF front end circuitry may support at least five carrier aggregation configurations between eight different operating bands. Two of the antennas are configured to operate at mid/high-band frequencies, while one of the antennas is configured only to operate at high-band frequencies. The third antenna along with the arrangement of filters in the RF filtering circuitry is used to support at least two additional configurations over those achievable by conventional RF front end circuitry.
