HMC471MS8GTR

Overview

The HMC471MS8GTR is a dual-channel SiGe HBT MMIC gain block amplifier from Analog Devices Inc., designed for surface-mount applications. It operates across a frequency range of DC to 5 GHz, making it suitable for WLAN and broadband RF systems. The device provides a typical gain of 21 dB with a P1dB compression point of 19 dBm and a noise figure of 4 dB. It requires a supply voltage between 6V and 12V and draws approximately 80 mA of current. Packaged in an 8-MSOP-EP format, this component integrates high-performance amplification in a compact form factor.

Feature Summary

• Dual-channel monolithic microwave integrated circuit (MMIC) architecture utilizing Silicon Germanium heterojunction bipolar transistor (SiGe HBT) technology
• Broadband operational capability covering direct current up to 5 gigahertz for versatile signal chain integration
• High linearity performance characterized by a 19 dBm output power at the 1 dB compression point

Applications

• Wireless Local Area Network (WLAN) infrastructure and client devices
• Broadband radio frequency signal distribution systems
• Test and measurement equipment requiring wideband amplification

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration distinct from the standard tube variant. Confirm the manufacturer status as discontinued or limited availability through official Analog Devices channels prior to finalizing procurement plans. Ensure compatibility with the specified 8-MSOP-EP thermal pad requirements during assembly.

Selection Notes

Select this component when dual independent amplification paths are required within a single package footprint. Consider the 6V to 12V supply requirement against available system voltages. Evaluate the 80 mA current consumption against total power budget constraints. Verify that the 21 dB gain and 4 dB noise figure meet the specific link budget requirements for the intended application frequency range.

Part Context

This part belongs to the HMC471 family of dual-channel SiGe HBT MMICs. It serves as a surface-mount alternative to larger discrete amplifier solutions. The MSOP-EP package provides enhanced thermal dissipation capabilities compared to standard plastic packages, supporting reliable operation in dense PCB layouts common in modern wireless communication hardware.

Replacement Considerations

Check Analog Devices documentation for direct pin-compatible replacements or updated series members. Verify if the non-trailing version HMC471MS8G is available in preferred packaging formats. Cross-reference specifications for any newer generation amplifiers offering improved noise figures or lower power consumption while maintaining the same footprint.
