HMC374ETR

Overview

The HMC374ETR is a general-purpose RF amplifier from Analog Devices Inc., designed for operation within the 300 MHz to 3 GHz frequency range. It utilizes GaAs technology and is housed in an SOT-23-6 surface-mount package. The device operates on a supply voltage between 2.75 V and 5.5 V, drawing a typical current of 90 mA. Key electrical specifications include a gain of 15 dB, a noise figure of 1.8 dB, and a P1dB compression point of 22 dBm. The third-order output intercept point (OIP3) is rated at 37 dBm, with an input return loss of 13 dB.

Feature Summary

• Utilizes Gallium Arsenide (GaAs) technology for high-performance RF amplification
• Designed as a cost-effective solution for wide-band medium power applications
• Features low noise characteristics suitable for sensitive receiver front-ends
• Supports single-supply operation within a standard voltage range

Applications

• GPS receiver front-ends
• Wireless local loop systems
• General purpose RF signal chain integration

Procurement Notes

Verify the specific suffix ETR confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the 90 mA supply current aligns with the target system's power budget constraints. Ensure the SOT-23-6 footprint matches the PCB design guidelines provided in the official datasheet. Validate RoHS compliance status against current regulatory requirements for the intended market.

Selection Notes

Select this component when a balance of low noise figure and moderate output power is required in a compact surface-mount package. The 15 dB gain provides sufficient signal boosting for many intermediate frequency stages. Consider the 2.75 V to 5.5 V operating range for compatibility with various logic levels. The 300 MHz to 3 GHz bandwidth covers multiple wireless standards without requiring external filtering adjustments.

Part Context

This part belongs to the HMC374G series of low-noise amplifiers manufactured by Analog Devices Inc. It serves as a fundamental building block in radio frequency integrated circuits. The device is distinct from evaluation boards like the 109258-HMC374, which are used for testing rather than final integration. It represents a mature GaAs technology node optimized for consumer and industrial wireless communications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official cross-reference tools or contact Analog Devices directly for verified alternatives. Ensure any replacement maintains the same SOT-23-6 pinout and thermal characteristics to avoid PCB redesign.
