HMC382LP3ETR

Overview

The HMC382LP3ETR is a low-noise amplifier (LNA) designed for GPS applications, operating within the 1.7 GHz to 2.2 GHz frequency range. Manufactured by Analog Devices Inc., this surface-mount device features a 16-QFN (3x3 mm) package with an exposed pad. Key electrical specifications include a gain of 17 dB, a noise figure of 1 dB, and a P1dB output power of 16 dBm at a test frequency of 1.8 GHz. It requires a 5 V supply voltage and draws 67 mA of current. The component is RoHS compliant and has reached end-of-life status.

Feature Summary

• Optimized for global positioning system signal amplification
• High linearity performance with 16 dBm output power
• Ultra-low noise figure for sensitive reception
• Compact surface-mount packaging for space-constrained designs

Applications

• GPS receiver front-end stages
• Satellite navigation systems
• GNSS signal processing modules
• Wireless communication base stations

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Analog Devices Inc. Procurement must rely on remaining stock from authorized distributors or secondary market suppliers. Verify part authenticity and condition carefully, as availability is limited. Consider immediate design migration strategies due to discontinuation. Check for alternative package types or direct substitutes if long-term production support is required.

Selection Notes

Select this component only for legacy designs requiring specific 1.7-2.2 GHz LNA characteristics with established board layouts. The 1 dB noise figure and 17 dB gain are critical for maintaining signal integrity in GPS paths. Ensure thermal management accounts for the QFN exposed pad. Evaluate replacement options like the HMC374E if new procurement is necessary, as the HMC382LP3ETR is discontinued.

Part Context

The HMC382LP3ETR belongs to the HMC382 series of RF amplifiers from Analog Devices Inc. It is specifically engineered for low-noise amplification in the L-band frequencies used by satellite navigation systems. The LP3ETR suffix indicates the 16-QFN package and tape-and-reel shipping format. It serves as a critical active element in RF front-ends where sensitivity and linearity are paramount for accurate position data acquisition.

Replacement Considerations

The HMC374E is documented as a similar substitute part number from Analog Devices Inc.
