GALI-39+

Overview

The GALI-39+ is a surface-mount monolithic microwave integrated circuit (MMIC) linear gain block manufactured by Mini-Circuits. It utilizes Heterojunction Bipolar Transistor (HBT) technology and operates from DC to 7000 MHz with a 50Ω impedance. Key electrical characteristics include a typical gain of 17.7 dB, a noise figure of 2.8 dB, and an output third-order intercept point (OIP3) of 26 dBm. The device supports a maximum input power of 13 dBm CW and requires a 3.5V supply voltage. It is housed in a compact SOT-89 package.

Feature Summary

• Wideband operation covering DC to 7 GHz for versatile frequency coverage
• High linearity performance suitable for demanding signal processing applications
• Low phase noise characteristics enhancing signal integrity
• RoHS compliant construction ensuring environmental safety standards

Applications

• Cellular infrastructure systems including PCS bands
• Wireless local area network (WLAN) equipment
• Test and measurement instrumentation front ends
• Broadband communication transceivers

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to ensure compliance with RoHS directives and lead-free requirements. Confirm that the SOT-89 package dimensions align with your PCB footprint design. Ensure that the operating voltage and biasing conditions match your system power supply specifications before integration.

Selection Notes

Select this component when a wideband, low-noise amplifier is required for frequencies up to 7 GHz. The high OIP3 makes it suitable for linear amplification tasks where signal distortion must be minimized. Consider the SOT-89 package size for space-constrained designs. Verify thermal management capabilities as the device dissipates power during operation.

Part Context

The GALI-39+ belongs to Mini-Circuits' GALI series of monolithic amplifiers. These devices are designed for general-purpose RF and microwave applications requiring reliable performance across broad bandwidths. The series is known for consistent lot-to-lot performance and robust construction using advanced HBT processes.

Replacement Considerations

Consult Mini-Circuits documentation for direct pin-compatible alternatives within the GALI series. Verify that any substitute part matches the DC to 7 GHz frequency range, 17.7 dB gain, and SOT-89 package constraints.
