GALI-84+

Product Overview

GALI-84+ is a MMIC gain block amplifier from Mini-Circuits. In an RF design it is normally used as a wideband 50 Ω gain stage, so the useful sourcing checks are not only the ordering code but also the operating band, gain behavior, output level, package footprint and bias conditions.

The published device data for the base part identifies DC to 6 GHz operation, with +16.7 dB nominal gain family. In practical BOM replacement, the suffix on GALI-84+ should still be checked for package, reel or screening differences before production use.

Key Features
