Overview

Description

The F1200 low-noise digital IF variable gain amplifiers (VGA) featuring FlatNoise™ technology is ideal for commercial radio systems with very high SNR requirements. Its extremely low distortion makes the device very flexible, while the 200Ω differential input and output impedances allow it to integrate seamlessly into the signal path.
