Switch protected low noise amplifiers (LNAs) are disclosed herein. In certain embodiments, a switch protected LNA includes an antenna terminal for receiving a radio frequency (RF) signal, an LNA for amplifying the RF signal, a first input inductor, a second input inductor, an inductor bypass switch connected in parallel to the second input inductor, and a shunt protection switch. The first input inductor is electrically connected between the antenna terminal and the second input inductor, while the second input inductor is electrically connected between the first input inductor and the shunt protection switch. The inductor bypass switch is turned on and the shunt protection switch is turned off in a receive mode, while the inductor bypass switch is turned off and the shunt protection switch is turned on in a transmit mode.
