GALI-21+

Product Overview

GALI-21+ is a Mini-Circuits RF gain block or connectorized amplifier module from Mini-Circuits. In an RF design it is normally used as a 50 Ω gain stage for RF lab, production or embedded wireless boards, 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.

For this model, the key application data to verify are: Mini-Circuits catalog RF range is model-specific; GALI/ERA/MAR gain blocks are typically wideband 50 Ω MMICs, while ZX/ZHL/ZFL are connectorized modules; nominal gain, P1dB, IP3 and noise figure are published on the exact Mini-Circuits model page/PDF; and single DC bias; connectorized modules specify voltage/current on datasheet. Because RF amplifier parts are layout- and matching-sensitive, GALI-21+ should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
