HMC287MS8E

Overview

The HMC287MS8E is a low-cost Low Noise Amplifier (LNA) designed for Bluetooth and WLAN applications operating within the 2.3GHz to 2.5GHz frequency range. It provides 21dB of gain with a typical noise figure of 2.5dB and an output P1dB of 3dBm. The device functions as a variable gain LNA, offering 30dB of gain control via 0 to 3V analog voltages. It operates from a single positive +3V supply with a current consumption of 9mA. The component is housed in an 8-MSOP surface-mount package.

Feature Summary

• Variable gain capability controlled by 0 to 3V analog voltage inputs
• Optimized for Bluetooth and WLAN signal chain integration
• Single positive +3V power supply operation

Applications

• Bluetooth receiver front-end stages
• WLAN receiver front-end amplification
• Low noise amplification in 2.4GHz ISM band systems

Procurement Notes

This component is officially listed as obsolete by Analog Devices Inc. Verification of availability should focus on remaining stock or authorized distributors rather than new production orders. Confirm the specific suffix MS8E matches the required pinout and electrical specifications before procurement. Cross-reference datasheet revisions to ensure compatibility with existing designs.

Selection Notes

Select this part when a cost-effective, low-noise solution is required for 2.4GHz wireless protocols. The integrated variable gain feature allows for dynamic range adjustment without external components. Ensure the design accommodates the 8-MSOP footprint and the 3V supply constraint. Verify that the 2.5dB noise figure meets system sensitivity requirements.

Part Context

The HMC287 series represents Analog Devices' MMIC solutions for wireless connectivity. This specific model targets the crowded 2.4GHz spectrum used by common short-range communication standards. It serves as a building block for RF receivers, providing necessary signal conditioning before downconversion or digitization.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the part is obsolete, engineers must evaluate alternative LNAs with similar gain, noise figure, and package dimensions.
