  • Patent number: 9705537
    Abstract: Embodiments of the present disclosure relate to a multi-mode RF system, which is capable of transmitting and receiving RF signals using any of multiple RF communications bands. The multi-mode RF system may integrate RF band specific bandpass filters and low noise amplifiers (LNAs) into a single front-end module, such that each filter and amplifier pair provide selection and gain for at least one RF communications band. Outputs of the LNAs may be combined to provide one or more common signals to a transceiver module, which processes baseband signals associated with the RF communications bands. By integrating the filters and amplifiers into a single module, the filters and amplifiers may be closely coupled to one another, thereby supporting short signal paths between the filters and amplifiers, and having impedances high enough to provide good filter selectivity.
