Abstract
A multi-mode power management circuit is provided. The multi-mode power management circuit includes an unlicensed band amplifier circuit configured to amplify a radio frequency (RF) signal for transmission in an unlicensed RF band(s). In examples described herein, the unlicensed RF band(s) resides in the 5 GHz RF spectrum and is shared between long-term evolution (LTE) enhanced licensed assisted access (eLAA) and Wi-Fi® connectivity. In addition, the multi-mode power management circuit can also support LTE communication in a licensed RF band(s). The multi-mode power management circuit can be dynamically and flexibly configured to support a variety of eLAA, Wi-Fi®, and LTE communication scenarios (e.g., uplink carrier aggregation) in licensed and/or unlicensed RF band(s) based on such power management schemes as envelope tracking (ET). In this regard, the multi-mode power management circuit can support eLAA, Wi-Fi®, and LTE convergence in a mobile device without compromising power management efficiency and/or increasing footprint.
