GALI-29+

Overview

The GALI-29+ is a wideband monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates from 0 Hz to 7 GHz and delivers a typical gain of 12.5 dB with a noise figure of 6 dB. The device requires a supply voltage of 3.6 V and draws 40 mA of current. Key performance metrics include a P1dB compression point of 11.5 dBm and an OIP3 of 25.5 dBm. Enclosed in a compact SOT-89 surface-mount package, it utilizes InGaP technology for consistent lot-to-lot performance.

Feature Summary

• Wideband operation covering DC to 7 GHz
• High dynamic range capabilities
• Repeatable performance across production lots
• Compact SOT-89 surface-mount packaging

Applications

• Cellular infrastructure amplification
• PCS band signal processing
• General-purpose RF gain stages
• Broadband communication systems

Procurement Notes

Verify the specific suffix designation when ordering, as variations may exist within the product line. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement. Ensure that the SOT-89 footprint matches your PCB layout requirements. Cross-reference the latest datasheet revision to confirm electrical parameters match your design specifications.

Selection Notes

Select the GALI-29+ for applications requiring broad frequency coverage up to 7 GHz with moderate gain. Its low noise figure makes it suitable for front-end stages where signal integrity is critical. Consider the SOT-89 package size for space-constrained designs. Evaluate the 12.5 dB gain against system link budget requirements to determine if additional amplification stages are necessary.

Part Context

The GALI-29+ belongs to the GALI series of wideband MMIC amplifiers from Mini-Circuits. This series includes variants such as the GALI-19+, GALI-39+, and GALI-49+, which offer different gain levels and frequency characteristics. These components share similar packaging technologies and are designed for high-volume manufacturing consistency.

Replacement Considerations

Direct substitutes within the same family include the GALI-19+, GALI-39+, and GALI-49+. When replacing, verify that the gain and frequency response of the alternative part meet the original design requirements. Ensure the SOT-89 pinout compatibility remains unchanged between the original and substitute components.
