Abstract
Embodiments include an apparatus, system, and method related to a switch circuit. Specifically, embodiments relate to a low noise amplifier (LNA) drain switch circuit that includes a first field effect transistor (FET) where the drain contact of the first FET is coupled with a gate contact of a second FET. The drain contact of the second FET may also be coupled with the gate of the second FET through a resistor. The source contact of the second FET may be coupled with a diode which may be coupled with an LNA.
