Abstract
This disclosure provides systems, methods, and devices for wireless communication that support low noise amplification of mmWave radio frequency (RF) signals. In a first aspect, a low noise amplifier includes a first stage amplifier; a second stage amplifier; a configurable first stage bypass coupled between a first input and a first output of the first stage amplifier; and a configurable second stage bypass coupled between a second input and a second output of the second stage amplifier. Other aspects and features are also claimed and described.
