    Abstract: Circuits and methods for an LNA that enable selection of a first mode providing high gain with wide output impedance matching, and a second mode providing wideband output impedance matching with improved NF and linearity at moderate gain. Some embodiments allow multiple intermediate modes to enable selection of gain versus linearity and NF. One embodiment includes a matching network having an input terminal configured to be coupled to an amplified-signal terminal of an amplification core, and an output terminal, the matching network including a first inductor coupled between the input terminal and a first node; a second inductor coupled to the first node; a boosted amplification branch coupled between the input terminal and the output terminal; and a non-amplification branch coupled between the first node and the output terminal; wherein the boosted amplification branch is enabled in a first mode, and the non-amplification branch is enabled in a second mode.

    Abstract: Methods and devices addressing design of wideband LNAs with gain modes are disclosed. The disclosed teachings can be used to reconfigure RF receiver front-end to operate in various applications imposing stringent and conflicting requirements. Wideband and narrowband input and output matching with gain modes using a combination of the same hardware and a switching network are also disclosed. The described methods and devices also address carrier aggregation requirements and provide solutions that can be used both in single-mode and split-mode operations.

    Abstract: A front end module having reduced number of low noise amplifier (LNAs) for receiving various combinations of contiguous aggregation (CA) signals and non-CA signals having different combinations of signals aggregated therein. The FECC can include a broadband LNA and/or a band-switching LNA having at least two modes of operation. An input switch directs a received signal to one of several banks of filters. LNA switches direct the signals from the output of filters within a selected filter bank to particular LNAs. LNAs may be connected by LNA switches to filters in more than one filter bank. The proper mode of operation is selected for the band switching LNA based on the particular frequencies present in the received signal and the filters selected.
