General Description

The SKY65374-11 is variable gain Low-Noise Amplifier (LNA) with an active bias and high linearity performance.

The first stage of the device is comprised of an LNA with a bypass switch that is followed by a high linearity driver amplifier, a variable voltage attenuator, and a high linearity power amplifier.

This module architecture provides excellent return loss, low noise, and high linearity performance.
