GALI-S66+

Overview

The GALI-S66+ is a monolithic RF amplifier from Mini-Circuits, designed for wideband applications spanning DC to 3 GHz. It features a typical noise figure of 2.7 dB and offers high dynamic range with repeatable performance across production lots. The device is internally matched to 50 Ohms impedance, ensuring efficient signal transfer without external matching networks. Encased in a SOT-89 package with an exposed metal bottom, it provides excellent heat dissipation capabilities. Powered by a 3.5V supply, this low-noise linear amplifier is suitable for demanding RF environments requiring stable gain and minimal signal degradation.
