GALI-74+

Overview

The GALI-74+ is a surface-mount monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates from DC to 1 GHz with a nominal gain of 21.8 dB and a noise figure of 2.7 dB. The device features an input return loss of 21 dB, a P1dB compression point of 18.3 dBm, and an output IP3 of 33 dBm. It requires a supply voltage of 4.8 V at 80 mA current draw. Packaged in a SOT-89-4 housing, it is designed for high dynamic range performance in RF applications.

Feature Summary

• Wideband operation covering DC to 1 GHz frequency range
• High dynamic range capabilities with low noise figure
• Repeatable lot-to-lot performance characteristics
• Surface-mount SOT-89-4 package design

Applications

• Cellular infrastructure systems
• Wireless communication networks
• Industrial automation controls

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Mini-Circuits or authorized distributors before procurement. Ensure the SOT-89-4 footprint matches your PCB layout requirements. Confirm that the 4.8 V supply voltage aligns with your system power architecture. Request official test data sheets to validate gain and noise parameters for your specific frequency band.

Selection Notes

Select this component when a wideband DC-to-1 GHz amplifier with moderate gain and low noise is required. The SOT-89-4 package suits space-constrained designs needing surface-mount integration. Consider the 18.3 dBm P1dB limit for linearity requirements. Evaluate the 2.7 dB noise figure against system sensitivity needs. Verify thermal management capabilities within the enclosed housing for continuous operation.

Part Context

The GALI-74+ belongs to the GALI series of low-noise amplifiers from Mini-Circuits. This series focuses on providing consistent performance across broad frequency ranges using InGaP technology. The component serves as a fundamental building block for RF signal conditioning in modern wireless systems.

Replacement Considerations

Consult Mini-Circuits documentation for direct cross-references. Generic substitutes may not match the specific 21.8 dB gain or 2.7 dB noise figure specifications.
