Abstract
Apparatus and methods for low noise amplifiers (LNAs) are provided herein. In certain configurations, an LNA includes a mode control circuit that operates the LNA in one of a plurality of modes including a gain mode and a bypass mode, a gain circuit electrically connected between an input terminal and an output terminal and operable to amplify a radio frequency signal received from the input terminal in the gain mode, and a bypass circuit electrically connected between the input terminal and the output terminal and operable to bypass the gain circuit in the bypass mode. The bypass circuit includes a balun that provides a first amount of compensation for a difference in phase delay between the bypass circuit and the gain circuit, and the LNA further includes a phase compensation circuit operable to provide a second amount of compensation for the difference in phase delay.
