Abstract
Apparatus and methods for overload protection of low noise amplifiers (LNAs) are provided herein. In certain configurations, an LNA system includes a switch having an analog control input, an LNA configured to provide amplification to a radio frequency (RF) input signal received from the switch, a detector configured to generate a detection current based on detecting a signal level of the LNA, and an error amplifier configured to amplify the detection current to generate an overload protection signal that controls the analog control input.
